Iridescent glass
Does anyone know how the iridescent coating on stained glass is
made, and what the stuff is made of? I'm wondering how to remove select areas on a piece. |

As always test on a scrap first -lauri |

The irid surface can easily and safely be removed with sandblasting or etching cream. If you want, you can return a full smooth gloss to the etched parts by fire polishing in a kiln. Pieces done that way can look delicately elegant. |

HFC is truly horrific stuff but the amount contained in Etching Creme is too little to be of serious concern. It's commonly used by thousands of hobbyists. For anyone considering using HFC, here's an article explaining why they should reconsider. http://www.glasscampus.com/tutorials...ric%20Acid.pdf |
