A Chemical Blotting Pad.

A cheap and excellent substitute for blotting paper may be made as follows: Mix 14 parts, by weight, of gypsum and two parts of potato flour, with sufficient water to form a plastic paste. Pour or press into a suitable mold. As soon as the mass has become hard and dry it affords an mirable blotter.
