Glass fusing is the heating of glass in a kiln to a point whereby it melts and fuses (binds) together permanently. It is often referred to as kiln fired glass and also warm glass (as opposed to hot glass for blown glass). Glass fusing is often combined with techniques like slumping, which is the method used to shape glass into or over glass moulds (sometimes spelt molds). This process is usually carried out at a lower temperature than fusing and as a separate firing. You can learn all about glass fusing on one of our courses.
