John Styler of Prospect Heights, Illinois asks

This conversation on flaws, damage, heat check etc. poses another question. Is there Museum Curator out there that would not consider having one of these pieces if it completed a set or complimented a display without telling the public, as a collector might; I doubt it?

Tommy Dreiling of Brooklyn addresses fleabites

I agree with Michael,Krumme especially on one point, if a chip, which I call a micro-chip and other people often call fleabites, are so small that you can only see them when the item is six inches from your face, and often time they can only be felt and not even seen, then to me I think it’s ridiculous to pass on items because they have “chips” and are not perfect. – Tommy Dreiling

Beth Shaut of Corning distinguishes heat checks from cracks

A heat check is very different from a crack. A heat check is an internal fissure that can not be felt at the surface of the glass being total contained inside the layer. Cracks can be felt by running your fingernail across the surface

Finally, Dick Stark of Potomac, Maryland talks about roses

a rose by any other name……….a crack is a crack…….some pieces have obvious cracks, usually the result of neglect. others may show a hairline which conceivably may be regarded as stress related, having occurred during manufacture (usually where application occurs) or perhaps later.. accordingly, I would ascribe the term heat check only to this later category.
