Undoubtfully precious items.
...And the illustrations are rather cute, indeed.
Are you familiar with the process ? What part of the material are those two guys 'cooking' ?

The Schweizerisches Landesmuseum Zürich had them analyzed, so here they are:

1. Outer incendiary layer:
88 % sulfur
10.4 % saltpeter/potassium nitrate
1.6 % carbon

2. Inner burning mass:
13.7 % sulfur
83.5 % saltpeter/potassium nitrate
2.8 % carbon

Matchlock - well, as some of the members here have been so very nice and provided me with information by private messages, I feel that I should give my real name:
