Grind a soft paste as follows:

50 pounds native red, powdered (88% Fe2O3);

23 "

magnesium silicate (asbestine);

27 "

raw linseed oil;

100 lbs.

Thin with 6 gallons raw linseed oil, 1 gallon brown japan or oil and turps drier, resulting in a batch of 13 gallons of red paint of fairly bright color, weighing close to 12 pounds per gallon.

Note. The 73 pounds of native red oxide and asbestine may be replaced with any good red oxide, containing anywhere from 30 to 40 per cent of ses-quioxide of iron.
