What is glass fusing? đ¤
At its core, glass fusing is the process of permanently joining compatible pieces of glass together by heating them in a kiln to temperatures between 1,300â1,500°F. As the glass softens, the molecules begin to move, allowing separate pieces to become one solid sheet. Depending on the temperature and firing schedule, the glass can fully fuse, tack fuse, or slump into a mold to create endless shapes and textures.
But hereâs the thingâŚ
Glass fusing is equal parts science and art.
Every firing schedule, glass thickness, compatibility test, and kiln cycle matters. Understanding heat work, annealing, thermal expansion, and the physics of glass is what separates consistently beautiful work from cracked, devitrified, or poorly fired pieces.
At The Glass Bar, we donât just dabble in glass fusingâwe obsess over it.
Our instructors spend countless hours researching, experimenting, testing new techniques, and pushing the boundaries of whatâs possible with kiln-formed glass. We make the mistakes, troubleshoot the failures, and perfect the processes so you donât have to.
Whether youâre making your very first project or diving into advanced techniques, youâre learning from instructors who are passionate about the craft and committed to giving you the strongest foundation possible.
If you want to learn glass fusing the right way, The Glass Bar is New Englandâs premier destination for expert glass fusing instruction.
Come see what happens when creativity meets science. đĽâ¨
