Does anyone recognize the maker of this large glass vase. Its very heavy 3500grms and stands 24cms in height. The glass has an acid etched look over a crackle pattern. The lower section only is clear (about 4cms) . The base has a smooth outer rim showing lots of wear, the inner part is unpolished but with a ground out pontil. No clues of maker. Its looks as if its full of crushed ice. Thanks in anticipation.
