Re: [ATM] Cold pitch

Mel,

I hate to disagree with you, but Gugolz pitch is graded by it's Melting 
point.

And it is all in Dergees C, not F.

http://www.melleroptics.com/shopping/datasheets_gugolz.asp

Even the 'softening point' of Gugolz 64 is still pretty high 150F. (66C)

And yes I see the chart does not align up exactly.

(Of course I am about to be put in my place... so I'll add...)
Now that's not to say Gugolz 64 just doesn't happen to work best around 
64F...

:)

Tom
