DD were waxed starting in about 1920 with stearin. Stearin is a
triglyceride and is found in heavy fats, animal and plant, palm oil being
one. It is insoluable in water and somewhat soluable in alcohol. It's
basically a hardener. I'm guessing it was mixed with alcohol for the DD.
Obviously
In the Blue Amberol book there is a description of the manufacturing
process. The last rinse leaves a slight lubricant on the cylinder. It
will be all gone by now even if the cylinder being examined is NOS.
Stearin is soluable in ether and benzene. Benzine was very popular in
years gone by
Thanks Rich,
I wondered about benzine (naptha) as it was widely used for many years as a
solvent. It evaporates quickly as well. My guess is that benzine was used.
Ether was even more flammable than benzine or alcohol... or they problably
would have been passed out sleeping on the job.

Ether goes anhydrous real easy and explodes. The benzine of yore is the
complete benzine ring. Naphtha is not the complete ring and lacks all
of the solvent properties of the old style benzine. It's also slightly
less likely to rot your brain.

Fascinating. I appreciate learning something like this from someone who
knows. Would you guess, then, that they used benzine as the stearin
solvent?
Just like everything else these days, what's on the label does not
necessarily mean what it did 100 yrs. ago. Benzine now comes in a can
During my chemical engineering days at school I actually dressed up as a
benzene ring one year. Don't ask - it was pretty stupid and I think alcohol
may have been involved. The terms naptha and benzine are used somewhat
interchangeably as can be seen on your can of benzine/naptha. Both
As was recently pointed out by another contributor. Benzine is a
mixture of solvents and benzene is the C6H6 compound of yore.
Benzine/Naphtha will not do an adequate job when compared to benzene.
To add to the grief benzene is almost impossible to buy and is
expensive. It is also not good
