A VARNISH FOR WOOD THAT WILL RESIST THE ACTION OF BOILING WATER.—Our readers will find the following receipt extremely useful:—Take a pound and a half of linseed oil, and boil it in a copper vessel, not tinned, suspending in the oil a small linen bag, containing five ounces of litharge and three ounces of minium, both pulverised, taking care that the bag does not touch the bottom of the vessel. Continue the ebullition till the oil acquires a deep brown colour; then take out the bag, and substitute another bag containing a clove of garlic. Continue the ebullition, and renew the garlic seven or eight times, or else put the whole in at once. Then throw into the vessel a pound of yellow amber, after having melted it in the following manner. To a pound of well pulverised amber add two ounces of linseed oil, and place the whole on a strong fire. When the fusion is complete, pour it boiling hot into the prepared linseed oil, and let it continue to boil for two or three minutes, stirring it well. Let it rest, decant the composition, and preserve it, when cold, in well-stopped bottles. After having polished the wood on which this varnish is to be applied, the wood is to have the desired colour given to it; for example, for walnut-tree, a slight coat of a mixture of soot with oil of turpentine. When this colour is perfectly dry, lay on a coat of varnish with a fine sponge, in order to distribute it equally. Repeat these coats four times, always taking care to let one coat dry before the next is applied. CORRECTIVE OF BAD WATER.—Five drops of sulphuric acid put into a full quart of bad water, will cause the noxious particles to fall to the bottom. The water should stand two hours; pour off about three parts for use, and throw the rest away. GLUE MADE WATERPROOF.—Soak glue in water till it is soft, then melt it in linseed oil, assisted with a gentle heat. This glue is not acted upon by water or damp.—X. WATERPROOF BOOTS.—Boots and shoes may be rendered impervious to water by the following composition: Take three ounces of spermaceti, and melt it in a pipkin, or other earthen vessel, over a slow fire: add thereto six drachms of India-rubber, cut into slices, and these will presently dissolve. Then add of tallow eight ounces, hog’s lard two ounces, amber varnish four ounces. Mix, and it will be fit for use immediately; the boots or other material to be treated, are to receive two or three coats with a common blacking brush, and a fine polish is the result.
