Dichro jewelry problem
Hi, I'm new here!
I've recently started making jewerly with dichroic glass and I've noticed that after firing, the dichroic layer seems to crack (like gold leaf) and/or shrivel somewhat. It looks kind of nice but I'm also looking for a smooth finish. I make sure the dichro layer faces clear glass, not another layer of dichro. What am I doing wrong?
Some info:
Ramp 1: Rate - 1200F to 500F. Hold for 5 min
Ramp 2: Rate - 1200F to 1250 Hold for 5 min
Ramp 3: Rate - 700F to 1450 Hold for 10min
Stop. Flash vent to 1000F. Cool to room temp with door shut.
The overall finish is good with nicely curved edges.

Re: Dichro jewelry problem
what brand of dichroic glass are you using? glass coated by cbs is the best dichroic coating...microdichro wrote:Hi, I'm new here!

some CBS colors fire up like foil, and do what you mentioned, like crackling. i have noticed that the premium colors do this, and sometimes green/magenta-blue, which fires magenta. also, silver (not red/silver) fires like foil. other colors seem to not have the problem. as your jewelry heats up and spreads out, the dichroic coating is also spreading, so it can give that crackled look you described. i'm sorry this is happening to your work -- i'm not nuts about it, either.

How many layers of glass are you using? Glass likes to be about 3 layers thick and will spread out or ball up to reach that thickness. You can also play with the placement of the dichroic...in the picture the small bits are with the dichroic face down aginst the base glass....the other pieces are a second layer face up. The green cabs have the dichroic floating in the middle.

My first dichroic tree split it looked like a branch so no big deal. The little jewlery kiln I use full fuses in the back and contour fuses in the front. The temp. seem to make alot of difference in the amount distortion. I've got "spots" that are best. Different types of glass crinkle more or less it takes alot of experimentation. Good luck. Fused Glass is a great medium.
