Irid

[Joe Wokovich]

I have an unusual shaped piece of black 96. It would be really great if it was in irid.
I’ve reading around for an answer for what I want to do, but have found nothing.
Is there a glass paint that would simulate the irid coating?

AAE Glass is selling a product called Glass Glo paints. They appear to be a dry mica cake that you can wet with water or other mediums. There's a video right now showing that they product an irid-like coating. The nice thing is, they're mixable.

Mother of pearl lustre is a good way to add an iridescent coating. The chemicals used on hot glass during manufacture are deadly toxic. The chemicals used in the lustre are not. Choose ceramic or glass based on what temperature you want to work at. You probably want ceramic. The glass ones are designed to apply to drinking glasses and not slump them in the firing. Compatibility is not an issue, because the deposit of chemicals is so thin.

Is there a link to pictures of this type of work? And to instructions on how to use these lustres? Thx

This is a how-to for pottery, but pretty much the same for glass. https://www.baileypottery.com/glazes/du ... .htm#Pearl Cone 020 is around 1180F, slumping temperature.

If you can find the Mother of Pearl Spray (I don't think it's made anymore), you just spray that on and then fire.

The look is like the inside of a clamshell (hench, the mother of pearl name). It's kind of iridized, but not quite like iridized glass.

Use a never used before brush and don't use it in more than one bottle, ie don't mix or you will contaminate it.
