| I.— | Boiled linseed oil | 5 to 7 parts |
|---|
| Gum thus | 2 to 3 parts |
| Non-drying oil | 3 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.— | Rosin | 8 parts |
|---|
| Rapeseed oil | 4 parts |
| Honey | 1 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 oil | 12 ounces |
|---|
| Rosin | 27 ounces |
Melt together and spread on paper sized with glue, using 12 ounces glue to 4 pints water.
| IV.— | Rosin | 8 ounces |
|---|
| Venice turpentine | 2 ounces |
| Castor oil | 2 ounces |
Spread on paper sized with glue.
