Abstract:
Rigid polyurethane foam (RPUF) used for imitation wood is typically prepared by using 1-dichloro-1-fluoroethane (HCFC-141b) as a blowing agent. However, this chemical is a hydrofluorocarbon which severely causes ozone depletion to the atmosphere. In this study, a more environmental-friendly RPUF was prepared by using distilled water and cyclopentane (CP) as alternative blowing agent. Several properties of the prepared RPUF were investigated and measured such as density (kg/m3), surface hardness (Durometer, type D), and glass transition temperature (°C) using differential scanning calorimeter (DSC). It was found that when the amount of blowing agents decreased, the foam density was increased as well as the surface hardness. The developed RPUF with CP co-blown has higher surface hardness and glass transition temperature compare to pure water-blown RPUF at the same density (353 kg/m3). And the new RPUF produced has a good potential to substitute for a conventional RPUF.

Abstract:
Glass blowing to create bottles with specific thickness distribution profiles requires several experimental iterations. Such iterations are expensive and increase the time to market. The use of simulation pretends to decrease the amount of prototypes by doing virtual validation of glass blowing molds. To feed simulations with realistic physical values, a gob drop test has been designed. This test provides valuable experience on the use of the software and validates heat transfer, viscosity and other physical parameters. Gob drop test was chosen for the possibility to record the test with infrared thermal cameras. Gob obtained similar shapes when dropped on a cast iron plate for both central and side sections with longer cooling of about 25°C. Such technique allowed the user to gain experience on the use of software and obtain valuable physical parameters for future glass blowing optimization.

Abstract:
Production of glass bottles requires blowing of the glass after entrance of a gob of molten glass in the blank mould. The final shape of the bottle is highly dependent on the viscosity of the glass, the blow-pressure and the temperature distribution in the glass and the mould and simulation of this complicated process enables optimization of the process conditions. During simulation of blowing of the glass, the mesh has to be adapted due to the extreme deformations of the mesh. To reduce the user-time and to be able to run this kind of analyses automatically based on an arbitrary base-geometry, a completely automated remeshing/rezoning procedure is set-up. Using the automated remeshing capability, simulations of the glass bottle forming process have successfully been performed, enabling for example optimization of process settings.

Abstract:
My work centers around the fact that I am a glassblower working with glass objects within a glasstradition. My BFA project from 2009 entitled ”the bastards have landed” was my first attempt atmapping out what that ultimately meant to me as a practitioner in a contemporary craft context. Theresult of that project was a discovery of my making as a way of using tradition to tell stories aboutitself. My conclusion was that by using the traditional objects as symbols I had a channel throughwhich I could communicate. Glass is a material who´s domains are closely connected to a domesticand consumeristic environment. It is put in a position where we react to its appearance with ourbody memory while also carries different social and material values depending on its appearance.When entering the master program at Konstfack University of Art Craft and Design, my idea wasthat over the next coming two years my focus would lie in the exploration and research of thesemechanisms as well as my own position as a maker and practitioner within these mechanisms.Craft, design and making are subjects that are constantly being talked about and analyzed from anumber of perspectives. There are philosophers, sociologists, historians and art historians constantlynegotiating what the field of craft is dealing with. This is something that I over the years have foundas something quite disturbing in some cases. This leaves me in a situation where I am no longerdefining my own practice. And when I am to define my practice I always do it through the ideas ofpeople from ”outside” my own position. There are many good writers from variousdisciplines writing about craft and making that I have had great use of and input from but I feel thatthere is a big lack of craft practitioners who are defining their discipline from their own standpoint.This situation is to me a bit outdated.So as mentioned above I have entered the master program with an idea to find out how to deal withveiled subjects such as tacit knowledge and material culture in order to try to transform them into acommunicative body of knowledge. My work during the past three semesters have been spread outover a number of different projects dealing with these subjects both based on objects as well asforming a discussion together with my master group.The main cause in this thesis is as always in my case to shed light on and to formulate questionsand hopefully answers around my own practice and its related subjects.The main reason for this is that craft and making as a tool for knowledge production is a cloudedsubject but according to me it holds a lot of potential. Not only for understanding questions outsidethe field but also to unveil and strengthen the practice itself.

Abstract:
Tacit knowledge is argued to be a crucial resource to organizations’ competitive advantage. The majority of research on tacit knowledge is oriented towards the conversion of tacit knowledge into explicit knowledge, thus assuming that all knowledge can be made explicit and captured in formal ways. These approaches overlook the intangible nature of tacit knowledge by overestimating that explicit knowledge.  This study takes a human centered approach with the aim to examine the factors that are necessary for an environment that works with tacit knowledge. A theoretical framework derived from the literature review and served as guidance for the data collection and analysis. Hermeneutics is the underlying philosophy that guides this study. The study is qualitative study conducted in the glass blowing in Sweden, respectively in two sites Pukeberg and Transjö Hytta. Participants of the study were masters and apprentices from these two settings. Data collection methods included literature studies, documents, participant observation, informal interviews and semi-structured interviews. Results from the analysis show the significance of several social factors that need to be present in an environment that involves tacit knowledge. These factors appeared to be related to each other. Data analysis indicated that not all factors are equally important, thus they have been classified into primary and secondary factors.

Abstract:
My engagement with making is a metaphor that contains the interior landscapes of my mind. I continue to explore it by comparing and contrasting exterior and interior, investigating surface and depth, covering and exposing, and taking apart and putting together. I work to translate my individual experiences and emotions into a tangible form. The visual dialogues that I engage in with my work explore a range of aspects that are inherent and specific to my Japanese cultural heritage. It often springs from my daily encounters with the subtle nuances and observable oddities of living in the “West”. These experiences have added to my self-awareness, and my sense of identity. I’ve always been fascinated by the visual phenomenon that occurs when light is transmitted, reflected, and/or refracted on/in/and through glass materials. I integrate these observable optical phenomena into personal narratives; by using “the-perceptional-shifts” that only the quality of glass it-self can generate, I transform my emotions into concrete materiality. The body of work that has developed over the past two years focuses on integrating my experiences, emotions and feelings, distance and time, and memories of and longing for my twin sister. I marry new technology with old, and attempting to bring the sensitivity of craft to new methods of making. Embedded in this work is my passion for life, materials, and making.

Pour prévoir et mettre au point la mise en forme d'articles volumiques en verre, les modèles éléments finis et les simulations numériques sont développées pour trois grands procédés : le pressage, le fluage et le soufflage. Par une formulation thermomécanique découplée, les modèles tiennent compte de l'écoulement newtonien du verre en présence des conditions de contact fortement évolutives au cours de la mise en forme ; la convection avec l'air et la conduction avec les outils sont estimes, soit par un modèle éléments finis en formulation implicite, soit de manière originale par un calcul analytique de la distribution de température limite à l'épaisseur de l'article en verre. Ces modèles sont utilisés avec succès pour une analyse de sensibilité des trois procédés aux paramètres géométriques et processus, en vue de leur optimisation et de leur validation, lors de la fabrication d'articles type issus des catalogues de fabricants verriers. Enfin, en s'appuyant sur le savoir-faire et les relevés expérimentaux, ces modèles numériques permettent la recherche de solutions adaptées, lors de la fabrication de deux articles de référence dans des situations extrêmes de formage.

Abstract:
La miniaturisation des systèmes d'imagerie présente aujourd'hui un fort potentiel dans plusieurs domaines, dont le développement de nouveaux dispositifs biomédicaux. Les exigences associées concernant l'imagerie demandent un effort substantiel dans le développement de composants optiques de haute qualité. Un meilleur contrôle de la propagation de la lumière ou de ses caractéristiques dans de tels systèmes est également important. Les composants doivent donc, par exemple, contenir les aberrations optiques pouvant affecter la résolution, la mise en œuvre de composants optiques dont le profil de phase continu est bien contrôlé est une voie intéressante. Ces composants devraient, de plus, être réalisés à partir de matériaux robustes en vue de leur assemblage au sein de dispositifs miniatures. Ce manuscrit de thèse de doctorat porte donc sur la conception et la fabrication parallèle de tels micro-composants optiques réfractifs réalisés en verre. Dans ce but, deux technologies ont été étudiées et optimisées, la lithographie à niveaux de gris et un procédé de soufflage de verre. En exemple, des microaxicons en verre ont été fabriqués et la génération de faisceaux de Bessel démontrée. Ce type de faisceau est caractérisé par une longue distance de propagation non-diffractive le long de l'axe optique, suivie d'une forme de faisceaux creux, qui les rend très utiles dans de nombreux domaines. Ces travaux de thèse ont été soutenus par le projet SMYLE (Small Systems for a Better Life) et le conseil Régional de Franche-Comté
Miniaturization of imaging systems shows nowadays a strong potential for many applications, in particular, e. g., for novel biomedical devices. Related imaging specifications require a substantial effort onto the development of high quality microoptical components. better control of light propagation and features in such system sis also of particular interest. Components should then e.g. contain optical aberrations in order to reach high resolutions. In purpose of searching higher diffraction efficiencies or resolutions, optical components with well-controlled continuous phase profiles are sought. In addition, they also should be made of robust materials to handle their further assembly into miniaturized devices. Consequently, the manuscript focuses on the design and the parallel fabrication of such microoptical components made of glass. To that end, two technologies have been studied and optimized, namely gray-scale lithography and glass-blowing processes. As an example, glass-based microaxicons have been fabricated and Bessel beams generation has been demonstrated. This type of beam exhibits a long non-diffractive propagation distance along the optical axis followed by a dark hollow shape which makes them useful in many different applications. This work has been supported by the SMYLE (Smart Systems for a Better Life) European project and the Ranche-Comté Regional Council

Abstract:
Embedding screenprinted transfers is one of several processes that can be used by artists as a means of expression to decorate blown glass forms. When screenprinted transfers are embedded into layers of glass and inflated, the imagery can be affected by a number of factors that limit the process. These limitations can include stretching and distortion of imagery, loss of density resulting in faded imagery and loss of clarity and detail of the imagery. Compatibility issues can also result in the artwork cracking. These limitations can result in the artworks being deemed unfit for their purpose, particularly when created for exhibition. This research addressed these limitations through the development of seven print inspired glass processes that alleviated or improved the limitations and provided alternative decorative processes to the use of printed transfers. This was achieved using a multi-method practice led research methodology approached from the perspective of a professional glass artist. To substantiate the research, several bodies of artwork were produced that developed and demonstrated the practicality and creative potential of the creative print inspired glass processes and extended the repertoire of visual effects that can be achieved when decorating blown glass forms. Throughout the research the print inspired glass processes were assessed for decorative qualities as well as the practicality of each process. To contribute to the limited technical knowledge currently available on the process of combining glass and print for the decoration of blown glass forms, the contextual review consolidated existing information. Technical guides relating to the seven print inspired glassmaking processes were formulated as part of the research.

Abstract:
Use of supercritical fluids (SCFs), particularly supercritical carbon dioxide, as alternative solvents in polymer synthesis and processing is a rapidly growing research area with successful industrial applications (McCoy, 1999). In some cases, the need for alternative solvents is based on environmental concerns, with regulations mandating replacement solvents. An environmentally mandated example is the 1995 ban of the use of chlorofluorocarbons (CFCs) as physical blowing agents in the manufacture of polymeric foams after CFCs were classified as class-I-ozone-depleting substances (ODPs). Among the alternative blowing agents are gases like CO2 and N2 and refrigerants such as 1,1-difluoroethane (R152a) and 1,1,1,2-tetrafluoroethane (R134a). Under the foaming conditions, at temperatures above the glass transition temperature of a polymer, and at pressures required for flow of highly viscous polymer melts, these alternative blowing agents are frequently supercritical. When polymers are formed into final products by various melt-processing techniques, such as extrusion, injection molding, blow molding, foaming, and spin-coating, extremely high melt viscosity presents a major difficulty. A common method to moderate the processing conditions is to add a liquid solvent or plasticizer to the melt. Solvents and plasticizers lower the glass transition temperature, Tg, of the polymer so that the polymer can be made to flow at lower pressures and temperatures. Replacing liquid solvents with SCFs presents unique processing advantages. Higher diffusivity and lower viscosity of SCFs, compared with liquid solvents, increase rates of dissolution and mixing. The properties of polymer–SCF solutions are tunable via pressure or temperature changes, thus allowing efficient downstream separations. Most importantly, dissolution of an SCF produces very large reductions in melt viscosity compared with a liquid solvent dissolved in the melt. Whether the interest in using SCFs in polymer synthesis and processing is driven by environmental concerns or processing advantages, it is important to understand the rheological behavior of polymer–SCF mixtures. In this chapter, we describe rheological measurements of polymer melts containing dissolved gases for two polymers, polydimethylsiloxane (PDMS) swollen with CO2 at 50 °C and 80 °C and polystyrene (PS) swollen with CO2, R152a, and R134a at 150 °C and 175 °C.

Abstract:
Hundreds of fragmentary glass cups preserve labeled representations of the empire’s leading sports stars, especially charioteers and gladiators. This mold-blown glassware illustrates how imagery common on popular terracotta plaques and lamps was adapted for upright translucent vessel walls. Comparing scenes reveals an important difference: whereas chariots are shown racing around the track’s monument-filled dividing line, gladiators compete without any indication of setting. When the cups are glimpsed at a utilitarian angle (45 degrees), they represent the events as they appeared from inclined stands and conjure the visual experience of spectacular entertainment. Most examples have been documented in the northwest provinces; in funerary, religious, and domestic contexts; and in places that did necessarily possess sports venues. Previously considered tools of Romanization or mementoes brought home from games, they were more likely commodities that found success in a competitive market for tableware by offering virtual experiences of the games in miniature.

Abstract:
Industrial glass blowing is an essential stage of manufacturing glass containers, i.e. bottles or jars. An initial glass preform is brought into a mould and subsequently blown into the mould shape. Over the last few decades, a wide range of numerical models for forward glass blow process simulation have been developed. A considerable challenge is the inverse problem: to determine an optimal preform from the desired container shape. A simulation model for blowing glass containers based on finite element methods has previously been developed [1, 2]. This model uses level set methods to track the glass-air interfaces. In previous work of the authors [3] a numerical method was introduced for optimising the shape of the preform. The optimisation method aims at minimising the error in the level set representing the inner container surface. The objective of this paper is to analyse the inverse problem by means of an analytical approximation of the flow problem and to improve the performance of the optimisation method previously introduced. In particular an initial guess of the preform for the iterative optimisation algorithm is constructed from the approximate solution of the inverse problem. The main goals of this work are the analysis of the inverse problem and the development of the optimisation method in consideration of the application to containers of industrial relevance.

Abstract:
Industrial glass blowing is an essential stage of manufacturing hollow glass containers, e.g. bottles, jars. A glass preform is brought into a mould and inflated with compressed air until it reaches the mould shape. A simulation model for blowing glass containers based on finite element methods, which adopts a level set method to track the glass-air interfaces, has previously been developed [1–3]. A considerable challenge in glass blowing is the inverse problem: to determine an optimal preform from the desired container shape. In previous work of the authors [4, 5] a numerical method was introduced for optimising the shape of the preform. The optimisation method described the shape of the preform by parametric curves, e.g. Bezier-curves or splines, and employed a modified Levenberg-Marquardt algorithm to find the optimal positions of the control points of the curves. A combined finite difference and Broyden method was used to compute the Jacobian of the residual with respect to changes in the positions of the control points. The objective of this paper is to perform an error analysis of the optimisation method previously introduced and to improve its accuracy and performance. The improved optimisation method is applied to modelled containers of industrial relevance, which shows its usefulness for practical applications.

Abstract:
In glass container manufacturing (e.g. production of glass bottles and jars) an important process step is the blowing of the final product. This process is fast and is characterized by large deformations and the interaction of a hot glass fluid that gets into contact with a colder metal, the mould. The objective of this paper is to create a robust finite element model to be used for industrial purposes that accurately captures the blowing step of glass containers. The model should be able to correctly represent the flow of glass and the energy exchange during the process. For tracking the geometry of the deforming inner and outer interface of glass, level set technique is applied on structured and unstructured fixed mesh. At each time step the coupled problem of flow and energy exchange is solved by the model. Here the flow problem is only solved for the domain enclosed by the mould, whereas in the energy calculations, the mould domain is also taken into account in the computations. For all the calculations the material parameters (like viscosity) are based on the glass position, i.e. the position of the level sets. The velocity distribution, as found from this solution procedure, is then used to update the two level sets by means of solving a convection equation. A re-initialization algorithm is applied after each time step in order to let the level sets re-attain the property of being a signed distance function. The model is validated by several examples focusing on both the overall behavior (such as conservation of mass and energy) and the local behavior of the flow (such as glass-mould contact) and temperature distributions for different mesh size, time step, level set settings and material parameters.

Abstract:
Industrial glass blowing is an essential stage of manufacturing glass containers, i.e. bottles or jars. An initial glass preform is brought into a mould and subsequently blown into the mould shape. Over the last few decades, a wide range of numerical models for forward glass blow process simulation have been developed. A considerable challenge is the inverse problem: to determine an optimal preform from the desired container shape. A simulation model for blowing glass containers based on finite element methods has previously been developed [1, 2]. This model uses level set methods to track the glass-air interfaces. The model described in a previous paper of the authors showed how to perform the forward computation of a final bottle from the given initial preform without using optimisation. This paper introduces a method to optimise the shape of the preform combined with the existing simulation model. In particular, the new optimisation method presented aims at minimising the error in the level set representing the glass-air interfaces of the desired container. The number of parameters used for the optimisation is restricted to a number of control points for describing the interfaces of the preform by parametric curves, from which the preform level set function can be reconstructed. Numerical applications used for the preform optimisation method presented are the blowing of an axi-symmetrical ellipsoidal container and an axi-symmetrical jar.

Abstract:
In glass container manufacturing (e.g. production of glass bottles and jars) an important process step is the blowing of the final product. This process is fast and is characterized by large deformations and the interaction of a hot glass fluid that gets into contact with a colder metal, the mould. The objective of this paper is to extend and further develop our finite element model [1] to be used for industrial purposes. To achieve this both steps of the forming of glass containers, namely blow-blow needs to be simulated and tested against real industrial problems. The model should be able to correctly represent the flow of glass, the energy exchange during the process and provide the final thickness of the final product. For tracking the geometry of the deforming inner and outer interface of glass, the level set technique is applied on a fixed mesh. At each time step the coupled problem of flow and energy exchange is solved by the model. Here the flow problem is only solved for the domain enclosed by the mould, whereas in the energy calculations, the mould domain is also taken into account. A non uniform temperature distribution is considered for the blowing of the preform. For all the calculations the material parameters (like viscosity) are based on the glass position, i.e. the position of the level sets. The velocity distribution, as found from this solution procedure, is then used to update the two level sets by means of solving a convection equation. A fast marching re-initialization algorithm is applied after each time step in order to let the level sets re-attain the property of being a signed distance function. The model is validated by several examples focusing on both the overall behavior (such as conservation of mass and energy) and the local behavior of the flow (such as glass-mould contact) and temperature distributions.
