An opinion from a glass maker, please.
« on: May 13, 2009, 09:01:13 AM »
Hi,
Please could you look at these images and let me know if you consider these to be tooling marks, or a chip? The glass where this imperfection is, is smooth, not sharp, to the touch. This is an Armando Jacobino hand finished "Pail" for Oy Kumela and is my own.

TIA
Della

If I know, I'll comment. If I think I know, I'll have a go. If I have no idea, I'll just keep quiet and learn from others, so the next time I'll know.

I am certainly no glass maker but it does not look like a chip to me, if it is smooth rather than jagged to touch then I would assume a tooling mark that maybe had been 'feathered' by the application of a some heat rather than a part polished chip.

It is always difficult to comment from photographs and it is often difficult to give an opinion when you have the piece in your hand, because everyone has their own method of doing things. Two people can do what seems to be the same thing and get a different result. That's the beauty of the hand working process and craftsmanship in general.

However, my opinion is that the rim has been pinched with tweezers - you can see a little groove - and then the pinched edge has been gripped with parrot-nosed shears to create a little ball or knop and pulled. As it is pulled the edge of the "handle" has become colder and the little knop has been broken off intentionally - you can see the tool marks - and then the rough edge has been fire-polished so that it is smooth and not sharp.

Therefore I do not think this is a chip. :)
