Havi, primarily I use Sunshine series that I mix myself with micas. I usually work in a single firing. Often I can get away with a single firing that vitrifies the paint and does a slump. Most often I am reverse painting and firing paint side down, so the painting comes out under glass. I like to us...

Havi, I have been screen printing enamels on glass for some 30 years and I have found out that the glass enamel itself is only a small part of the overall complications. I started out as a printmaker too and have found that the complications of screen printing on glass are many. Your screening tech...

Bert, I think I have some Samba powders, which I also bought there. I was told that I could mix it with BE powders, in order to enhance the BE colors, Do you know anything about it??? Thanks Havi Havi, my information might not be correct. I don't really know. Ferro does manufacture in Europe. Beats...

Thank you Bert, I bought Colorline paints from their manufacturer, who is CREATIVE GLASS in Volketswil Switzerland, near Zurich. Perhaps they have some agreement with BE -behind the curtains. I bought the paints directly form them, as I took several classes there. I know them, and they know me, the...

I am probably driving you crazy, I think the paints I used were fuse master, not Thompson. would the above work with them too. Sorry :( Fusemaster is entirely different. Their colors are a clear glass frit mixed with metallic oxides. They do not generally do well when applied as powder. They are de...

Bert, Thanks for your response. However, I can not understand how do know that I am applying a too thick layer of ink????????????????? I wonder. On the contrary, being a printmaker, and my experience as such - I have the feel of how much ink should be applied. I do not know anything about Ferro col...

i'm fusing sheets of the same glass and same COE, so there shouldnt be any issues there (if I understand correctly). The one time I had a warp, it was with a single sheet of 10mm thick float glass. The problem was caused by too big a gap between bricks that surround my kiln. I refired it with the b...

Thompson makes many different lines of enamels, all of which are ground colored glass frits, compatible with different substrates including different glasses. Once the layer of enamel is thick enough, incompatibility will cause cracking. On every single glass fusion project, you can fire as fast as ...

Havi, you are applying too thick a coating. This causes the orange peel effect or cracking and volcano effect. (thinking about it I think orange peel is caused by under firing) These colors are really strong. Color line are really Ferro Samba series. These are similar to the Ferro Sunshine series bu...

thank you all for your comments. All great ideas, which I will try. I can't fuse it to too high of a temp because I can't have the pieces round out too much. But perhaps a little higher temp will work. And I will check to make sure my kiln shelfs are flat. And try to hold at 1100 on the way down. B...

There are various reasons why glass might warp. A simple one that can't be fixed is a compatibility issue where the top and bottom layers are contracting at different rates. The only thing you can do there is configure it differently. I have seen glass warp when there was a gap between bricks in my ...

Bert, don't you mean that ss shrinks more than glass, thus the potential of a ss mold trapping the glass? I've not has a problem unless the ss mold is a full hemisphere. Yes Nikki. I have many drafted ss molds that work fine. The glass is able to ride up, and does;t get stuck. I also have hemispher...

I once repaired a refractory cement bowl mold using putty I made with vermiculite board dust. The first attempt at fixing the mold was with kiln wash. That didn't work. The putty worked real slick. So, whatever works...

A great source for vermiculite boards is Jim Wiles in Charlotte NC

You can use some coarse sandpaper and make v-board dust. Mix it with rigidizer to make a putty and fill in any holes.

There is a good possibility some glass is shitty, others not so much...

The painted pieces didn't fog. They should have fogged. Maybe I cleaned them too well. No conclusions yet. Guess I'll try a piece that has only been cleaned with dish soap. If it doesn't fog, I'll find something more productive to worry about. Paint is an overglaze which provides a different surfac...

Merry New Year!

That stuff doesn't happen to me. First, I never fire thinner glass than 6mm, and usually 10mm. I do routinely paint vitreous colors (mixed with Micas) on the tin side, then fire to 1420' paint side down.
