_How to make stouple, or prepare cotten-week to prime your fire-works with._ Take cotten-week, such as the Chandlers use for candles, double it six or seuen times double, and wet it throughly in saltpeter water, or aqua vitæ, wherein some camphire hath been dissolued, or, for want of either, in faire water; cut it into diuers peeces, rowle it in mealed gunpowder, or powder and sulphur; then dry them in the Sun, and reserue them in a box where they may lie straight, to prime Starres, Rockets, or any other fire-works. _How to know the true time, that any quantity of fired Gun-match that shall doe an exployt at a time desired._ Take common gun-match, rub, or beat the same a little against a post to soften it; then either dip the same in salt peter water, and drie it againe in the Sunne, or else rub it in a little powder and brimstone beaten very small, and made liquid with a little _aqua vitæ_, and dried afterwards; trie first how long one yard of match thus prepared will burne, which suppose to be a quarter of an howr, then fowre yards will be a iust howre. Take therefore as much of this match as will burne so long as you will haue it to be ere your worke should fire, binde the one end unto your worke, lay loose powder under, and about it lay the rest of the match in hollow, or turning so that one part of it touch not another, and then fire it. _A Water called_ Aqua Ardens. Take old red wine, put it into a glased vessell, and put into it of orpment one pound, quicke sulphur halfe a pound, quicke lime a quarter of a pound; mingle them very well, and afterwards distill them in a rosewater still: a cloth being wet in this water will burne like a candle, and will not be quenched with water.
