ATM pitch to soft

["Larry Davis" <Davis@digdat.com>]

Hello everyone ;  This is my first mirror. I just poured the pitch lap in a
mould, using Texereau as  guide. Moderate thumb nail pressure indents the
pitch in about 3 seconds. This is very much softer than the 10 sec. heavy
thumb nail test according to Tex. ( I think ). Before stripping mould and
cooking pitch again I wanted to consult the list to see if any of you had
other options or a more precise test for pitch hardness. I,m using medium
hardness burgandy pitch as supplied by Newport Glass.   Hoping to avoid dumb
mistakes, thanks.   LFD
