1932. To Powder Glass

1932.    To Powder Glass. Heat the glass red-hot, throw it into cold water; dry, and pulverize it, coarse or fine as required, m an iron mortar. It is used to filter acids; is glued upon paper or muslin for polishing; also to rub down corns upon the feet, after they have well soaked and dried.

1933. To Make Glass Paper or Cloth

1933.    To Make Glass Paper or Cloth. Powder the glass (that with a greenish hue is the best), and sift it through a very fine wire sieve, to separate the finest portion of the powder; this is for the smoothest degree of glass paper; sift the remainder successively through sieves gradually increasing in coarseness, to suit the different degrees of the glass paper required; keep the result of each sifting separate. Then smooth on both sides, with pumice stone, any good tough paper, and tack it on a board; a tolerably fine quality of muslin is far preferable to paper. If large sheets are used it is better to glue the edges on a frame (similar to a small quilting frame), and when dry, damp the paper or muslin and stretch it, in the same manner as the muslin is strained for sized roller blinds. Give the surface a coating of strong glue size, and immediately dust the glass of the required fineness equally and thoroughly all over, using the same sieve that was used to separate it from the rest of the powdered glass. When dry, throw off the surplus glass for future use.

1934. To Make Stone Paper

1934.    To Make Stone Paper. As, in cleaning wood-work, particularly pine and other soft woods, one process is sometimes found to answer better than another, we may describe the manner of manufacturing a stone paper, which, in some cases, will be preferred to sand paper, as it produces a good face, and is less liable to scratch the work. Having prepared the paper as described in the last receipt, take a quantity of powdered pumice stone, and sift it over the paper through a sieve of moderate fineness. When the surface has hardened, repeat the process till a tolerably thick coat has been formed upon the paper, which, when dry, will be fit for use.

1935. To Make Emery Paper or Cloth

1935.  To Make Emery Paper or Cloth. This is prepared in precisely the same manner as glass paper (see No. 1933 (To Make Glass Paper or Cloth)), using emery instead of glass.

1936. Phenyl Paper

1936.     Phenyl Paper. This article would be useful for packing meat and other substances liable to decay. (See No. 1614 (To Make Carbolic Acid Paper for Preserving Meats).) It can be prepared by fusing 5 parts stearic acid at a gentle heat, mixing well with 2 parts carbolic acid and 5 parts melted paraf-fine, and stirring until the whole has become solid, and applying it to paper in the same manner as waxed paper is made. (See No. 1938 (To Make Waxed Paper).)

1937. Solvent for Silk, Paper, etc.

1937.      Solvent for Silk, Paper, etc.. The ammonio-oxide of copper is a solvent for silk, paper, and the cellular tissue of plants. If its action be limited to a few moments it converts the surfaces into a gelatinous mass.
