Part three of a series on glass fusing.
Now I've shared most of the terms one hears in fusing but there are a few more, full fuse, tac fuse and slumping.
Full fuse is when those two or more layers of glass are heated up and melted completely together into one solid mass. Tac fuse is when the glass is heated up and allowed to melt just enough to "tac" it together. The glass on top is still has a distinct shape and yet the edges have rounded and it has fused to the bottom layer of glass. Slumping is when the glass is heated enough to for it to bend and sag or "slump" into the desired shape.
Now I'm not going to get into temperatures, different holding times and heating/cooling cycles. With all the wonderful modern computer technology out there one does not have to be a rocket scientist to learn to fuse glass. One can acquire kilns set up for fusing that come equipped with a digital controller. This wonderful gadget (to my knowledge) comes all programmed for fusing.
With time one learns more about all this and can tweak the cycles to their personal preferences.
