Amanda Simmons

Specialism: Drop Out Techniques

Amanda makes kilnformed glass objects, playing with gravity in the kiln. Manipulating mass, heat, colour and time, she creates complex, elusive work that has intense colour and pattern which reacts to the light it is placed in. She uses opaque glass powders to construct her work because of its varying translucency as the form elongates in the kiln, then finishes the pieces using many coldworking processes. Amanda graduated from Central St Martin’s School of Art & Design in London with a Postgraduate Certificate in Glass & Architecture, before relocating to Dumfries & Galloway, Scotland. She has exhibited in many high profile national and international exhibitions.

In 2008 Bob moved his studio to Salt Spring Island, British Columbia where he makes glass art and writes e-books on his signature techniques. Bob is a popular guest instructor on the international kilnformed glass scene.

Here are some of the internationally renowned artists that have previously taught in the Warm Glass studio:


Alicia Lomné

Specialism: Pâte de Verre

Alicia Lomné works with the glass kilncasting technique of Pâte de Verre; literally translated from French it means 'paste of glass'. The process includes creating a model, making a mould, placing thin layers of powdered or fritted glass within the mould, and then firing the piece in a kiln. Alicia works primarily with open faced moulds and is most compelled by the exact colour placement and sculptural possibilities that Pâte de Verre offers. Alicia has dedicated the past twelve years to exploring techniques in Pâte de Verre. She shows her extraordinary work in galleries across the U.S. and has taught Pâte de Verre workshops around the world.

Deborah Horrell (1953-2018)

Specialism: Pâte de Verre

Deborah Horrell (1953-2018). Deborah received her MFA from the University of Washington in 1979. After working as a ceramist for many years, she explored wood and bronze. Horrell then began investigating glass at the Pilchuck Glass School during a residency in 1994. A residency at the Bullseye Factory followed in 1996, permanently redirecting the trajectory of her career. Her work was shown in museums and galleries nationally and internationally. Working with the Pâte de Verre process, she created beautiful objects which play with the balance of strength and fragility. Sadly, Deborah lost her six-year battle with cancer in August 2018. Her passing is a huge loss to the artistic community. She was a truly inspirational artist to learn from.


Jane Bruce

Jane exhibits her work internationally, it can be found in many major museum collections worldwide, including those of the Victoria and Albert Museum. Jane has taught extensively in the US as well as in Canada, Europe and Australia.

Jeremy Lepisto

Specialism: Flameworked Beads

After graduating with a BA in Fine Art from Alfred University (Alfred, New York USA) in 1997, he made his way to Portland (Oregon, USA) and was hired to be the Production Manager Apprentice at the Bullseye Glass Company. This role allowed him to work in every facet of the Bullseye factory’s glass production areas as well as with any visiting artists who came to work at the factory. In addition, he was engaged to teach classes and research new glass chemistry and processes; this experience formed the basis of his glass kilnforming knowledge. In 2001 he left Bullseye and started an independent studio. (Photos by: Rob Little)

Joseph Harrington.jpg__PID:0e5b3beb-a783-4a29-8a1c-6872b2b09642

Joseph Harrington

Specialism: Glass Cast Sculpture

Joseph Harrington is a sculptor working predominantly in cast glass. He graduated with an MA in Ceramics and Glass from the Royal College of Art in 2006. The main principle within his work is to create a sense of time and movement within a permanent object. Joseph has a fascination with turning one thing into another, the reaction of materials and energies acting upon each other. He has developed a unique working method using ice as a modelling medium. The ice is eroded and sculpted with salt then cast into glass, capturing a moment in time as the ice is melting. This thawing of ice provides a physical time frame to work within, heightening the importance of artistic judgment and decision-making.


Kathryn Wightman

Specialism: Glass Tapestry and Blown Glass Forms

Wightman’s work evidences a fascination of process and materiality explored through the exploitation of illusory imagery. She utilizes glass to mimic textile surfaces, which aim to challenge the viewer’s sense of reality. Hybrid decorative patterns are deconstructed to create multiple layered compositions. Each layer is stacked to add depth, allowing the patterned forms to grow from the surface of the glass. Wightman obtained her BA and MA from University of Sunderland (UK). In 2011 she completed Ph.D. research (University of Sunderland, UK) focusing upon the development and application of creative printmaking processes for the decoration of blown glass. She recently relocated to New Zealand to teach at The Wanganui Glass School.


Mikyoung Jung

Specialism: Glass Cast Sculpture

Mikyoung Jung originally from South Korea, graduated with a Bachelor of Fine Arts (BFA) from Namseoul University (South Korea) in 2005, majoring in glass. She earned her Masters in glass with distinction at the University of Sunderland, U.K. in 2007. She then moved to Australia to continue her research and started her PhD in Visual Art at Sydney College of the Arts, developing a new range of glass artwork. Mikyoung’s work reflects her experiences of living abroad, from different landscapes to alternative cultures, and the way in which these experiences have affected her.


Miriam Di Fiore

Specialism: Kiln Formed Landscapes

Manda has been a bead maker since 2005. Developing her business Mango Beads, she has built a unique body of work and is well known for her eclectic use of colour. Much of her work is cabochon-based and her Harlequin and Sundial designs, sold as pendants and ring toppers have become very collectable. Manda is an internationally acclaimed lampwork instructor; the classes and workshops she gives have awakened a passion for teaching she never knew she had. The opportunity to share her skills with others perhaps just beginning their journey in lampwork is a constant reminder of how lucky she is to have discovered beadmaking and the joy it brings with it.

Simon Bruntnell.jpg__PID:5a6da963-b183-48b3-b6f6-97c7645dedcd

Simon Bruntnell

Specialism: Glass Photography

Simon is a photographer based in the UK who gained an international reputation for his images of contemporary glass. From Simon's website: "The photographic image of a work of art reaches a much wider audience than the physical piece itself. The relationship between the artist, the photographer, and their respective media is therefore a crucial one; doubly so when the artefact is formed from glass. Simon has, during his career to date, developed into the specialist in this field bar none. The quality of his images is the result of an ability to work with the artist in developing an understanding of and approach to each object that has resulted in images that have been reproduced and deservedly appreciated worldwide."
