I picked up a P2K 8K Type 21 riveted tank car, off the bargain table,
lettered "Philadelphia Quartz Co. Soluble Silicates POX 517", build
date 5/51 (I model 1952).
I have several elementary questions.

Wish I had acquired one too....

What was/is the Phil. Quartz Co.?
Much information via their web site at

I think in the steam era one of the larger uses of silicates was in the making
of soap.
