Is there a story on why your father had a tremendous supply of shaving Soap chip-powder?
Yes. In the late 1930s, my father did a renovation for a man who owned barbershops. When the job was finished several cartons arrived at the house. Two cartons consisted of containers of shaving chips or powder. My mother told me that the owner of the barbershops was pleased with the job my father did and sent the package as a gift.
I did some research a few years ago and learned that in the 1920s and 1930s a few companies such as Colgate and Williams made and sold soap powder. Unfortunately, it is no longer made today. However, the Colgate and Williams containers were relatively small in contrast to the containers my father had.
As a kid. I would watch my father shake some powder and put it into a mug, add some water and stir with a shaving brush. He would "paint" my face with the lather on occasion.
When I started shaving in about 1956 I used the same product and used it the same way. What later surprised me was how fast you could make lather with this product. Another benefit was that if you added too much water to the mix all you had to do was add some more powder.
