Hi all,
I have made up a nice batch of black powder and it was extremely fast....
When I came to granulate it, it went very well and it has been drying for over a day now but the granuals are extremely brittle and crumble very easily?

Is this normal or not?

Thanks
Rob

Depends really, riced BP made with red gum can be a bit brittle...

What binder (and what % of binder) / solvent / method did you use?

I always use 3% Dextrin for 100g batches, with mixed with 50% Water, 50% Alcohol, comes out rock hard.
