TESTING JAPAN.
If japan smells of benzine don’t buy it. Mix it with clear oil; if it curdles, you don’t want it. Mix drop black with some of it; as stiff as good drop black ground in japan; then thin with turps and make a painting test, to see if it is a good binder. To see if it will crack, paint on glass, let it dry and hold the glass between your eye and the light. If you see fine cracks don’t buy any of it.
When you go to buy japan, ask the dealer who made it. If he don’t know, make up your mind at once that it is a fatherless waif without a name, and likely to be worthless. When a man makes a good thing he is apt to send his name along with it as an advertisement. This applies to all material. There is a great deal of bad japan on the market, and a great amount of work ruined by it. Buy none unless it bears the brand of a reputable maker and will stand these tests.
I do not need to tell the practical painter that there is a great amount of bad japan on the market, and that a great deal of paint is ruined by it. Buy no japan unless the can bears the name of some reputable manufacturer, and will stand the above tests.
