How To Make Emery Cloth

Buy some emery powder. By washing in water (as before explained), get the different degrees of coarseness, cover a piece of thin cotton cloth with a light layer of glue, sprinkle over it the powdered emery. But it is better to buy the cloth all ready.

How To Make Glass-Paper

Take any quantity of brokeu window-glass, that which has rather a green appearance on the edge is the best, pound it in an iron mortar, then have two or three sieves of different degrees of fineness ready for use when wanted. Take any good tough paper (fine cartridge is the best), level the lumps on both sides with pumice-stone, tack it at each corner on a board, and with good clean glue, diluted with about one-third more water than is used generally for wood-work, go quickly over the paper, taking care to spread it even with your brush; then, having your sieve ready, sift the pounded glass over it lightly, but to cover it in every part; let it remain till the glue is set, take it from the board, shake off the superfluous glass into the sieve, and hang it in the shade to dry; in two or three days it will be fit for use. This paper will be much better than most of that which you can buy, sand being frequently mixed with the glass, and coloured to deceive the purchaser.
