Tack Fusing Schedule for Float Glass

Tack Fused Recycled Glass - "Geometry 2"

Tack fuse (contour fuse) firing schedule

Use this schedule for Stainless Steel Ribbon Molds, Tempered Glass Ice Plates and Bottle Glass chunks. This schedule rounds the edges and tacks pieces together, but does not full fuse.

(1/4″ window or 2 layers bottle glass chunks, coarse frit)

You will need to test this schedule in your particular kiln. My kilns range in tack fuse temperature from 1435F to 1450F. Test and adjust accordingly!

Tips and Trouble Shooting:

If the gap is too small to slide pieces together, you’ll need to widen it with either a diamond file or a diamond bit on a dremel tool. Use plenty of water and wear a mask.
Make sure the feet are level, if your vase isn’t balancing, you may need to grind the feet larger and flatter
If your fiber paper doesn’t come out cleanly, add water and dig it out with a skewer or hooked wire.
Yes, the vase can hold water
