I.—Boiled linseed oil5 to 7 parts
Gum thus2 to 3 parts
Non-drying oil3 to 7 parts

For the non-drying oil, cottonseed, castor, or neatsfoot will answer—in fact, any of the cheaper oils that do not readily dry or harden will answer. The proper amount of each ingredient depends upon the condition of the boiled oil. If it is boiled down very stiff, more of the other ingredients will be necessary, while if thin, less will be required.

II.—Rosin8 parts
Rapeseed oil4 parts
Honey1 part

Melt the rosin and oil together, and incorporate the honey. Two parts of raw linseed oil and 2 parts of honey may be used along with 8 parts of rosin instead of the foregoing. Use paper already sized, as it comes from the mills, on which to spread the mixture.

III.—Castor oil12 ounces
Rosin27 ounces

Melt together and spread on paper sized with glue, using 12 ounces glue to 4 pints water.

IV.—Rosin8 ounces
Venice turpentine2 ounces
Castor oil2 ounces
