Topic: Applied colour to interior of vase ?

[Anne E.B.]

I'm guessing my cleaning caused the colour loss to the interior of this piece near the rim   But I'm curious as to what it actually is.  The pieces that came off looked as though they could be a thin plastic coating.   It also reminded me of nail varnish - the bits that flake off, except that the pieces curled up.

Any ideas what it could be, and how it was applied?  Is it just enamel?   I just didn't expect it to come off .   I was told it dated back to the 1950's(ish) or thereabouts, so would this tie in with the way in which colour was applied?

TIA

colour coating is widely used by the Chinese to embellish cheaper clear glass. If you want to remove all I suggest you soak it in a vinegary solution. Normally the stain is sprayed onto the outside, and the bottom stays clear - giving us a change not to be bothered. Inside coating is nasty, however....

I'll put the vinegar to better use - on my fish and chips
Thanks Ivo :thup:
