I am making a table top that is 27 1/2 x 20 that has to fit within an 1/8" lip. Using 2 pieces of 1/4" glass airbrushed. I tried it firing to 1480 with lots of annealing time in between. The glass had a lot of movement and was to big. Do you have to dam the sides or can you fire it to a lower temp and hold it longer. It was held for 30 mins at 1480. Thanks for your help.

Deena you can always dam a piece. It isn't surprising that it flowed, glass wants to be 1/4 inch thick. Dam with fiberpaper and cut up kiln shelves.
Check out Vitrum Studios for great classes in the DC area (okay so they aren't in VA, but they are close enough...).

Deena-If you hold it longer at a lower temp to get the same fuse result that you get at a higher temp you will still have a flow problem. I think Barbara is dam right. I use everything from from fiber board and brick to stainless tubing. In a pinch have even used glass wrapped in fiber as a dam, though I would not normally recommend that. Your other choice is to fuse it undammed, and trim after, which may be easier said than done.
