Blue smokey swirls with bubbles
« on: January 25, 2012, 04:14:23 AM »
This one is 2 7/8" inches at its widest point, 4 1/2" tall with a 1 1/4" base.  No markings on the base.

Here's a base shot of this weight.

It's probably modern Chinese. Those matte bottoms often (but not always) indicate Chinese

What are the little pin-pricks on the base? I've seen those before and have left on the shelf assuming that if it were good quality they would have been ground away.

They are probably remnants of the pontil scar, but those in themselves are not an indicator of poor quality. You can find them on highly polished bases; you can only remove so much of the base without ruining the item.

Thanks Christine,
I've seen very similar before. There are 3 in this pic and the pattern suggests 4 (tool) marks originally.
Good to know that I have to rely on other knowledge before dismissing other items in the future!

They are not tool marks. Paperweights are made on the end of a glass rod and when the item is cracked off what remains is the pontil scar/mark. It may be a lump; it may be a hole.

From what I can see those "pin-pricks" are just air bubbles within the glass that were opened when the bottom was ground away.  A little more grinding might well remove them, and is likely to cut open more bubbles in the next layer of the glass.

Or maybe even bits of grit (or similar) in the annealing oven that have caused indentations which were deep enough to partly remain after grinding. Possbly?
