193. CROCKERY CEMENT

Dissolve 1 oz. of common salt in 1 quart of water, bring to a boil, and put in 1-1/4 lbs. gum shell-lac; when it shall have dissolved, pour into cold water, and work like wax; make into small sticks. This will make crockery as firm as a rock. Directions: Warm the stick, apply it to the broken edges, then heat the edges, place them together and hold for a minute, and they are firm.

194. A CEMENT FOR CHINA, GLASS-WARE, &c.

Take a thick mucilage of gum arabic, and stir into it plaster of Paris to form a thick paste, apply to the edges with a brush, and press firmly together and confine them two or three days, and you will be astonished at their firmness.
