Title: Neodymium pear
Post by: chriscooper on March 06, 2011, 09:39:42 PM

Any thoughts, maybe Zelezny Brod? (Czech) after doing some research also came up with Konst Glasyttan Urshult (Sweden)

Thanks for looking.

no idea who is to blame for the pear shape - but please do not keep it in the window sill. It looks dangerous there.

Two replies for the price of one here Chris:

1. Yes, I am pretty certain it is Konst Glashyttan Urshult....I have several pieces with labels with the semi-blown interior in neodymium glass.

2. Ivo is right....get it off the window sill !!.....I have very badly scorched wooden sills as a result of placing rounded glass pieces on them....one burn is so deep it was actually smoking when I realised what was happening....if we had been away at the time.........!!!!! :phew:

the other problem is more serious - an large enclosed bubble in a thickwalled glass has a different expansion quotient, so if you expose it to heat the internal pressure can increase. If you're lucky this results in a crack - but worse things have been reported.
