Fake carnival?

Frank, I'm stepping right outside my comfort zone now.  :shock:  Thinking aloud...... cold lustering techniques can also be used. I think this can produce very light (I have heard people incorrectly describe it as "flashed") iridescence.

I haven't scratched any fake carnival (and perhaps a definition is needed for "fake" but this is perhaps not the place for it), but I would not think it is possible to scratch the iridescence off  - for example - the Far Eastern Good Luck, Peacocks etc. The iridescence on pretty much all Carnival (as far as I am aware) is, in old fashioned parlance, burnt on. Iridised when HOT (directly after moulding/shaping).

Cold iridising of a sort can be done by "water ambering" in certain natural springs. It has also been done as "one-offs" on some old EAPG pieces (mainly Heisey) through a post production "decorating" process that I believe was applied cold luster. The iridescence on them is pale and very watery - and of course, they are "rare" (in other words, only a handful of them were iridised).

It's a big topic. I've only scratched the surface  :roll:

I am sure that Pirelli's would have been fired. There are of course many firms now providing coatings for glass and some of these are very hard to detect until they start to wear and loose the shine. Mostly based on plastics technology. I wonder if anyone has tried using such methods to create 'collectible' items.

Annealing ovens work in the range of 600-800 fahrenheit.
