These stains must be made from permanent unfading colors mixed with some medium which readily penetrates the wood, and which is indifferent to the effect of weather.

A good cheap base is 3 gallons of water white, 150 degree test petroleum oil, 2 gallons of crude creasote oil, and 1-2 gallon of good liquid dryer, tinted the desired color.

For a better grade of shingle stain, use 2 gallons of raw linseed oil, 2 gallons of turpentine, 1 gallon of creasote oil and 1-2 gallon of dryer, tinted as above.

The creasote used should be clear and not too dark or heavy. Crude carbolic acid can be substituted, and is lighter and clearer than ordinary creasote or dead oil.

Shingle stain need not contain creasote, but may be made in the usual way from raw oil, turpentine and dryer. Linseed oil stains tend to turn black after exposure, when used on shingles.
