Export Putty.

—The above recipe answers for putty that is to be sent abroad, the cotton oil preventing it from going hard. Sometimes the white lead is omitted.

Putty for Exposed Positions.

—A very strong putty is made of boiled oil and whiting and is suitable for exposed positions, such as skylights. It is not adapted for keeping, as it gets too hard. Putty for inside work that is ground in raw linseed oil may be made by adding a little white lead.

Hard Putty.

—Mix dry red lead with boiled oil and turpentine varnish. This may be used immediately, as it soon gets hard.

French Putty.

—Boil 7 parts of linseed oil with four parts of brown umber for two hours. Then add 5¹⁄₂ parts of whiting and 11 parts of white lead and mix the whole. This putty is very durable and adheres well to wood.

Imperishable Putty.

—Various recipes for a so-called imperishable putty have been given. The one published above, named French putty, is very durable, but it may be varied by boiling together for two hours 3¹⁄₂lbs. of linseed oil and 2lbs. of brown umber. Stir in one ounce of beeswax, take off the fire, and mix 2³⁄₄lbs. of whiting and 5¹⁄₂lbs. of white lead.
