how much glass ?

[slats]

I was taught to use 2 layers of glass plus design layer. I recently saw some beautiful large fused plates 20 in. which were only one clear layer plus colored design on top with nice rounded edges. When I tried this I got spikes. The artist suggested raising the shelf higher than what I do...raise to ABOVE the lower side coils so that the heat is completely UNDER the shelf (I have top and side elements) Any suggestions here?

Spiking, erose edges, and any other phenomena related to the glass trying to achieve it's equilibrium thickness can be overcome by LOOKING in the kiln and stopping the fusing process at the appropriate time.

However, I personally find the appearance of one layer plus design to be somewhat . . . insubstantial.

Brock, what is the best height for the shelf? Above lower coils or level with them

for what?

if you put them above, you get a baffling effect. however, the glass doesn't heat up as fast. if you're firing small stuff, you can heat glass very quickly, and thus putting it close to the top elements is useful.

I've been using the Spectrum clear 96 double thick for disks and platters. I just place my design elements on the double thick, fire and get beautiful results. There's no need to worry about air being trapped between layers of glass and you get a "substantial" look.

Thanks Judy......The work I saw was quite substantial as well.....Does BE also have this double thickness? I only use 90? Ill have to check it out.... thanks
