I have a few questions on firing glass paint. It's very simple black enamel lines on yellow GNA, 4 x 6 piece. What temp and for how long? I actually want the reams on the glass to go away, which will be a better match, so can I fire it higher and/or longer? Do I need to wait for the paint to dry before firing if I use paint thinner? Thanks!
The type/company of paint dictates the firing temperature. Typical trace black fires at 1225-1250. You can set the kiln to high and go to the 1225, then turn off the kiln to cool. to smooth out the glass lines you may need more temperature and this could burn out the paint. You will also pick up texture from the kiln shelve. Paint thinner? You don't use paint thinner with fired paint. But, yes the paint needs to be dry before firing or you could cause it to blister.
It was a very old bottle of too thick paint, so I used a bit of paint thinner on it. It went on well, but will this now not work?
Don't know. Try it and let me know. Various oils are used to mix paint. Never heard of using a solvent.
The producers of Paradise Enamel Glass Paints actually recommends the use of paint thinners and mineral oil with their products.

True, but they also say that their paints come pre-mixed in "pine oil". Solvents thin oils. Most dry pigments are made liquid by adding water. Oil is used for silkscreening,fine line work etc. So before you thin with a solvent, you need to know whats in the paint.
may i know some of the varieties of glass painting?tips for it?precautions to take when painting?
Absolutely agree, Vic. Oil and water are only good for salads.
Since JK didn't state whether his old enamel paint was latex or oil and since "once burnt, twice cautious" may apply (see April postings of a, ahem, minor fire), I just wanted to pass on one manufacturer's info to assuage any fear that JK might have of a re-occurrence and to let him know that he most likely would not have another kiln fire if he used paint thinner.
So, JK...fire that puppy up!

Thank goodness I got your approval...... woo hoo, here I go.
I apologize for my enthusiasm.

Report on firing black Dekka paint on yellow GNA. Fired to 1200. As it approached 1100 or so I peeked and the black started to disappear. Now all that's left is faint white where the black used to be. What did I do wrong besides doing it myself? Wrong paint? Temp too high? Ready to try again.
You ****** *****. Dekka paint is a lacquer based COLD paint. You do NOT fire it. Why didn't you say it was Dekka?
You need to be more specific. Are you talking about fired paint or unfired?
That is incredible! It hung in there until 1100? You own a copy of "Painting on Glass"?
I won't go further, and I shall control the urge to ROFLMAO, nope can't control it, got to do it......
Everybody has to be the first at something,,,,, you got that one.
DON'T FIRE DEKKA, IT'S HOBBY PAINT!
Paradise paint will do the job.

For him it would be easier to access Reusche, thru any of the stained glass distributors, or he knows where to send it to have it done inexpensively.
Well it was worth it to get you off your hiatis! (Where do I get it done inexpensively?)
DOH! I have this box of leftover paint bottles I inherited. How do I know which ones are firable?
Me thinks you need to make a trip to British Columbia next month and attend a "glass festival".
I thought Dekka paints were only fired in house oven to around 250 degrees.
