Dear glass messages
Thank you for such a wonderful site so informative and knowledgeable.
I have just bought a vintage art glass vase - black and yellow swirls - ball shape with lipped top - 13.5cm high x 13.5cm wide with the vase hole 3.5cm wide. To the base hand etched around the pontil mark is the makers mark that I can not decipher - it is something "crystal" followed by a number "20154005" I have attached a photo of the mark in the hope someone will be able to help me identify the maker history etc. I can add more photos if required.
Thank you in advance for any help you can give me.
With best regards
Glassamore
