Re: Ball of light?

Probably a good looking "ball of light" is in the eye of the beholder. There's a lot of variation in what that could mean or look like. Still, I like the idea of a rounded clear ball over yellow gold dichroic, just use a larger "bead" rather than a small one. You could also consi...

Re: FIRE POLISHING

Really hard to do that, Barry. We've had pretty good luck reheating cast life-size turtles to shine them, using a firing schedule not unlike your suggestion (only to around 1350), but the problem is having to remove scratches. That takes a higher temperature or a much longer hold and is much more li...

Re: FIRE POLISHING

Havi, if it's a flat piece it can easily be fire polished, assuming the scratches aren't that deep. Just fire to 1400F/760C and hold about 10 minutes, then anneal as usual. If the scratch is deeper, you need to go high, to as much as 1460F/790C or so. If it's not a flat piece, it's a lot harder beca...

Re: can't figure out what I. did different

Generally, blue bubbles come from a copper compound. They'll give you the beautiful bright blue bubbles in your piece. If you put too much copper (usually copper oxide) it will have black ugly areas like your other piece. Firing too high can also cause this problem. My guess is that the mica you're ...

You sure it's mica powder you added? Looks like copper or a copper oxide.

Re: Does a new kiln controller come already programmed?

New controllers do have a program (or programs) in them. It's usually not a full fledged firing schedule, but a few steps that are used to test the controller out.

Re: strange result

How high did you fire? You'd have to fire pretty far above normal fusing temperatures to get the glass to flow off the kiln shelf.

Re: keeping Texture on glass

If you tack fuse at a low enough temperature you'll keep most of the texture. 1350F/730C is high enough to stick glass together and retain most of the texture. The higher above that you go, the more texture you will lose.

Re: first attempt with new kiln

To help you, we'll need to know what firing schedule you used, what glass as well.

What happened when you tried to upload the picture? What format was it?

Re: calculating the amount of glass for a mold

What you want to test is what the glass will look like. Small frit vs large frit, for example, will look very different. And different colors as well. Basically, before you spend a lot of money on glass, spend a little money with a smaller mold to make sure the color and transparency will be what yo...

Re: calculating the amount of glass for a mold

Get a container. Put water in it. Mark the level of the water. Pour some water into the mold. Mark the new, lower level of the water. Now fill the container with glass until the water raises to the original level (the first mark). That's how much glass you need. The smaller the pieces of glass you u...

Re: painting crisp, even thickness lines

There's not a huge difference in the way the Colorline paints work than the Sunshine.

To get an absolutely straight line, use a resist and paint through that, rather than by hand.

We use Sunshine Enamels. Mixed properly, they work like oil paints or acrylics.
