Glass chips at the rim and fades, when the mass itself bears the color, in full sun. A signature in the base is the proof and, at the same time, the place where you must not grind along the piece. In the overview Security for collectors, collector glass sits next to porcelain.

What breaks without a thief

Impact, a shelf that is too tight, heat, a lid that sticks and that you lift by force. You store with air between the pieces, heavy ones low, light ones not on the edge. You carry a heavy piece with both hands, at the body.

Fragile and often left standing, but a small signed bowl is easy to take. It does not stand by the door. Anchor the display cabinet, do not leave the cabinet door open when tradespeople walk through. The list knows the signature.

The folder

Artist or manufactory, model, dimensions, signature as a photo, damage, proof. A chip on the foot that was already there is photographed with it.
