Topic: Help needed with unusual textured bowl.

[cubby01]

It looks like the texture is a combination of processes, first crizzled <...> then it looks as if an acid treatment was used to get the small spots.

Thank you John.  To me, that's exactly what it looks like has been done.  'Crizzled' is a term I had not associated with this technique.  (I think crizzling may have another meaning in reference to glass, a type of progressive deterioration.)  I can see how the term is applied here.  The finish on the bowl is somewhat close to what I'd call 'crackle' finish but not quite.   

I don't think it was made in a mould to produce the texture - there are bubbles in the crizzle-y bits, sort of air trapping.

That's correct Sue.  No mould.  It was definitely blown and cut.  And yes some bubbles are trapped in the lacy lines.

Been trawling the recesses of my brain for the correct name for this process.

(Dipping the hot gather in cold water to create this surface texture, before reblowing)

I believe it is actually prima vera.

Crizzling is the name for very old glass which has sort of jig-sawed itself into tiny bits with cracks, but was the name used by Michael Harris for this technique when he used it at Mdina and IoWSG.

Unfortunately, having spent most of my glass time concentrating on Mr. Harris and all his connections, crizzling is the word I automatically use for this surface treatment - whether on the surface or inside a piece.

Crackle fits nicely.
