Blackpowder keeps gooping to yellow and black goops.

[dimitri]

I made black powder and when burning it creates goops one of the hardened blobs is on the floor/surface and is yellow (maybe sulfur) and reacts somewhat violently with water. The other is more normal it goops into black smaller globs even without sugar the black powder is traditional recipe. I'm just eyeing the proportions so that may be why.
