Once upon a time, a company, possibly named Engelhard (sp?), sold a product, possibly named called "Thermoluster," in colors that may have included something called "Mother of Pearl."
Akin to Tetra-Butyl-Titanate, this stuff could be sprayed on finished ware prior to annealing and would create iridescent-like effects.
After scouring the web, I cannot find a current source.

The plan is to apply this, or something similar, to production, Raku-fired, ceramic field tile.

Does anyone know of a current source for this or a similar product?

Ten years ago, Engelhard got out of the marketing biz and got in bed with Reusche (http://www.reuscheco.com/). Product should still be the same. Try them first.

You can try Duncan (http://www.duncanpaintstore.com/lusters-overglazes) as well, but they're not "glass people."

You can fume with this stuff ?

I think the term fume is thrown around too loosely.

Spraying stannous in my opinion isn't fuming, it's irridizing.

Sticking a hot gather into a pile of stannous and letting it smoke up onto the piece is fuming.

Some of us have called spraying stannous onto a piece "fuming" for 45 or more years now. We called putting stannous into a gob of hot glass "fuming" as well and did it because we didn't have a spray booth. Stannous certainly makes glass iridescent. I think the Iso titanates do a terrible job of irridizing.

I don't know if they still do, but W.R. Grace had it at one time.
