Example text

The idea is to build up a slug of powder within a tube, set it aside to dry for several weeks, then peel off the paper; it is then crushed and screened. The grains can be swirled with some graphite in a saran-wrap covered bowl to finish. 30 A technique related in Foxfire 5 is even simpler: flatten the dampened mass with a rolling pin on a stone slab and set it out in the sun to dry. Crumble the dried powder and use it! Results are probably quite similar to powder manufactured in Europe after the 1300s and very much like the powder homemade by settlers.

The lift powder was poured into the bottom of the case, and the perforated disk was placed over the lift powder. The stars were then placed over the disk. The bare end of the quickmatch was nestled into the stars, but not more than one-half of the way to the end-disk. This was then finished. The purpose of the disk is to prevent the stars from commingling with the lift powder, and to help force the stars out of the mine. I began by experimenting with five ways. All of them had the following similarities for the purpose of this test.

The light suddenly dawned on me: the first test I conducted when I measured a rate of 105cm/second had used a generous amount of Black Powder, the others quite a bit less. I had actually made a conscious de- 29 cision to use less, in order not to waste any of my batch of valuable fast-burning Black Powder! But why the differences in results? I found the answer to this question through repeated experiments. Proper testing required that the line of Black Powder being tested contain enough Black Powder to ensure that most of the granules were actually physically touching their adjacent granules.
