Irridescent spray for glass firing

Hi....I have read about a formula for spray that makes glass irridescent but, of course, now I can't find it! Anyone familiar with it or other interesting home made surface decoration formulas? Thanks and have a great holiday, Elizabeth

Here's a link to the tutorial about making your own.

Be careful, this not something you want to try in your kiln. I saw it done recently by a glass blower with lots of ventilation. The fumes are very corrosive.

There are also a few sprays for ceramics that sometimes work on glass. Most of these are sprayed on, then fired to around 1150 or so. I've used a Duncan product with some success, but there are a number of irid sprays for ceramics out there.

Brad, if I am not mistaken Duncan no longer packages their mother of pearl luster in the spray can. It is packaged in one ounce liquid form for application with a brush or spraying through an airbrush. Med-Mar no longer produces lusters for ceramics. A search for "china painting supplies'' should turn up several sources for small quantities of dry colors suitable for use on fused glass. Many of them also sell the various lusters.

Best wishes,

You can also spread a thin coating of "super sparkle" (or any other color) mica powder on a piece of ceramic fiber and fire on top of it to get an iridescent effect on the bottom of your glass.

I've used a couple different made-for-glass lustres from Rynne China. In their catalog, its misleading as to which of their lustres work on glass. I had to call them to get the right stuff. But the results look like irrid to me.

What is the reddish lustrous stuff that Diane Trepano used on her 2003 magnet? Is that mica?

Watched for the "how to list", but must have missed it. Searched the archives also. Where is it?
