Hi. Does anyone have any suggestions about this bowl. It's a nice heavy piece, slightly tinted blue with colour inclusions. Thought it might be worth taking a punt on as it is very good quality. The label on it in the shop just say's 80/90's glass, so not much help. It is signed on the base but i couldn't get a good pic of it. The first word starts with a 'T' the second i'm pretty sure starts with a 'P'.
