Cracked Lid

[gordon stelter]

Evaporation of volatile components. Bacterial decay. (
See J.Garret's post about brittle action parts. )
Granted this would be less a factor in a veneered and
sealed component. But a definite  possibility, I
think.
    You have probably observed how  many open-faced
blocks are in better shape than their covered
counterparts? I think this has a lot to do with the
varnish on them. Perhaps we should varnish our new
blocks befor installing?
( If we believe in doing top-notch work, vs. planned
obsolescnce, that is, as do I! )
