Looking for any information on this glass vase. It is signed on the bottom SI (could be a no. 1) 22.6.99 which must be the date. The blotched pattern on front is normal, colours are fused into the glass. The larger blotches on back are rough/sandy feeling and on the surface of glass. I'm guessing this is a mistake? 200mm high and 75mm across top. The thickness of top rim glass is 10mm.It's a pretty little thing. I can see a bunch of sweetpeas in it next summer!
