To Make Slowmatch.
ОглавлениеDissolve 1 dram of nitrate of lead in 1⁄2 an ounce of boiling water. Cut a sheet of blotting paper into six equal parts, and wet them on both sides, with a sash-tool, with the solution. When dry, paste a piece all over, and upon it smoothly press another piece; upon this, pasted, put a third piece; and so on, till all the six form a stiff board. Lay them under a heavy weight; and, when dry, with a sharp knife and straight-edge, cut the whole into strips 1⁄4 of an inch broad. Four inches will burn about a quarter of an hour. Narrow tape, boiled in the solution, makes excellent slowmatch.
