Barytes In Chrome Yellow

The detection of barytes in chrome yellow is a very simple matter, and as it is a very commonly employed adulterant, the following may be found useful: Put a small portion of the yellow into a test tube, add a sufficient quantity of concentrate muriatic acid, and boil. The yellow is almost immediately resolved into a white semi-crystalline chloride of lead and a green solution of chloride of chromium. A large amount of water is added to the test, which is again boiled. If there is no barytes present, a clear solution will be formed, as chloride of lead is soluble in boiling water. The barytes, if present, will be left behind as a heavy, fine white deposit, which may he washed by repeatedly boiling with water.

Bathrooms

These should be warm in coloring, to assist a feeling of warmth during the winter toilet, and they should of course be washable in every part, as otherwise the steam from hot baths may destroy the work in a very short time.

Lakes and vermilions are very fugitive when exposed to the light, and an endeavor must be made to mix them so as to retain their beauty and natural color the longest possible time. Varnish containing no resin gum has been found by experience to extend their life and beauty the longest.
