Re: transparent glass turns opaque

Very common, especial with reds. The higher the temperature, the more likely.

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.

Re: painting crisp, even thickness lines

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

Caveat: we also sell them: https://www.warmglass.com/enamels

Re: New Studio - New Kiln

I owned a Nabertherm GF240 fiber kiln for nearly 10 years. It performed flawlessly, required less electricity than a smaller brick kiln, and was my go-to kiln for larger projects. Nabertherm is German; the kiln has fiber sides and top, with a brick floor. The fiber is rigid, not blanket. I eventuall...

For fiber, top only should work.

Most likely the color will change or fade, but it's worth a try.

.2mm should be thin enough. Try a small piece as a test.

Re: copper inclusion

2mm is too thick. It will almost certainly crack.

No formula that I'm aware of. It would depend on the particular metal, of course.

Re: Using oxides as colorants

Michael Stevens wrote:how could make the painting medium?


You can use anything that will mix with the oxides and that burns off cleanly in the kiln. Many glues will work or if you can get some ethyl methyl cellulose or carboxy methyl cellulose (CMC) you can make your own glue that will work well.
