Most would think of glass as the last material one would want to store and carry powder in but glass flasks and horns did exist and actually saw use in the woods. They are rare and the survival rate is probably very low but examples can be found. Some were made as novelty items and by artisans to show their skill and some seem to be production items such as the flask shown here from my collection and identical to the one in figure 14 pg. 2 and described on pg. 4 of the linked pdf. Dismissing the ones made to hold perfume (Avon) and spirits like George Dickel we can find ones actually made to hold black powder and to be used. The flask illustrated was blown into a mold and has quite heavy walls which would make it difficult to break but still not unbreakable. The very few photos of the flask style I have found do not have a mechanism on the top but rather a wood stopper in a few cases.
I tried filling the flask with powder, salt and also empty in an attempt to show the scene with 3 grouse which is prevalent on both sides and found the best photos were taken empty on a black background.
