Cleaning iridescent vase
« on: August 27, 2012, 06:01:03 AM »
Another odd question, on maintaining iridescent vases. I have an 05 Eickholt vase that has a pearl, iridescent coating on it. I'm just curious, is this a cold applied finish or is it done when hot? Will it rub off like some carnival glass or is it done in a kiln??

I'm just curious as I don't have any other pieces that are like this and I want to ensure I properly care for it, if ever needed.

Thanks in advance,

Sorry if in wrong section. I was a bit confused where this should have gone until after posting.
I love my generic ashtrays!!!

Iridescent finishes on glass are generally created by spraying the hot glass with metal salts, which actually bond to the glass. They shouldn't rub off with normal cleaning, although harsh chemicals, abrasives and wear will remove the top layer of glass and consequently the iridescence. It's not like an enamel coating.

The most gentle way to clean such items is a good soak in room temperature water containing enzymatic (biological) washing liquid. Gunge will just lift off with a soft paintbrush.
Best done in a plastic basin, but if you have to use the sink, place a towel in the bottom - just to as a safety precaution.
