Anyone know anything about this one? Saw it and had to have it. It reads Vulcanizing Solution Mfd. By The M. & M. Mfg. Co., Akron, O. Stoneware type bottle this short caught my eye.
We see quite of few of those here in Ohio, they seem to sell well.. I am not positive but think they were for sealing bicycle inner tubes rather than tire making..
I believe when tires were patched back then they used natural rubber. The repair then needed to be 'vulcanized" to make it harden. Natural rubber will start to melt on hot pavement if it isnt vulcanized.
Vulcanizing is done with heat and pressure. I have mad hundreds of jewelry molds by vulcanizing natural and synthetic rubber. Vulcanizing solution will seal a patch on a tire or inner tube through a chemical reaction and is called cold vulcanizing. There was also tire patching glue that you had to light and preglued patches that you had to light.
