Christine - thanks, I didn't know about the ashtray tax - when was this (probably long before my time

) - sounds a bit like the glass vase tax that you cud avoid if you attached the word Celery. Think my one wud do for peanuts.
Anita - thanks for the interesting link for Mandruzzato. Unfortunately, my flea bites are truthfully bigger than flea bites - and are almost certainly impact damage.
I have a 12" dry sanding disc on the end of a lathe - and it had occured to me at the time I first acquired this piece that it might be possible to remove a small amount of glass on some of the panels, but suspect its essential that water is involved. In a former life I had a lapidiary set up with a horizotal plate and various grits (and the running water) which wud have been ideal for this sort of thing - now all parted with, but I might have a go again one day. I notice that on all these pieces (I have) that the sharp edges where the panels join have all been bevelled - obviously to help prevent this potential problem of flaking. Paul S.
