This is called Phenolic-Formaldehyde-Resin: All the materials for this formula can be purchased from any wholesale drug house.

Extreme Caution:

Should be taken when mixing this formula. You should only use a glass or stainless steel vessel, and perform the operation in a place where the fumes will dissipate. Either in open air or into a chimney. These products should never come into contact with the skin. They are highly irritating and corrosive.

Materials Needed:

Pure Phenol (carbolic acid) crystals, Formalin (30%
Formaldehyde), Caustic Soda (sodium hydroxide) or lye,
Lactic Acid, Clycerine, and Hydrochloric Acid.

Quantities are given by weight, so that you may make any desired amount of resin.

Formula:

In a vessel mix 1 part phenol with 2 1/2 parts of formalin. Add caustic soda a 20% solution in water, in the amount of three parts to 100 parts of the phenol and formaldehyde solution. This mixture is then heated for about 6 hours at 150 to 160 degrees F. Remove the water formed by the reaction. When the resin has become a thick syrup, add 6 parts of lactic acid and 15 parts of glycerine. Continue to heat until a small sample congeals on cooling. Add Hydrochloric Acid, 1 part to 100 parts of the mixture by weight, and when sufficiently cool, pour into dies of lead or plaster.

Hardening tie depends on so many factors it is hard to predict. It will dry quicker if heated in an oven at 120 to 140 degrees F. The product will be water-white, and may be colored with dyes or pigments if desired.
