[78-L] Glass Compound 78s

[Ron L]

Is there any reason why one could not apply a tiny amount of fingernail
polish to a flaking area to stabilize it?

Very simple..assuming that it's sturdy enough for you to handle without it 
breaking (and those things are VERY thin), hold it up to the light. If you
see 
translucent bluish, yep..it's glass based. As for the flaking, that's not 
reversible.

If you find this somewhat risky, you can tape the edge lightly with your
ring 
finger. The sound will be different from tapping an aluminum disc.

Not all manufacturers identified glass lacquers, except on the sleeve, which

was pretty dumb. Amazing that 65 years ago, these things were able to be 
shipped..carefully, yes, but they frequently made it intact. They must have 
been a bit more flexible when they were new.

was playing a record from 1942 and I noticed the sunlight was sparkling off
the record in a rainbow of color, as if the light was being reflected
through a prism.  I examined the record closely and discovered I could see
brightly lit images through it.  It has an unfortunate crack and the edges
of the crack seem to be flaking off like glass.

the edges are flaking off?
