You can find alum powder usually in the spice section of your local grocery store. It can be used for a variety of things. It can be used in cosmetics, for medical, and also in culinary applications.
Star Molecule, hands down. It was faster burning, hotter, and a military grade aluminum powder at that. It worked better than German Dark (by far) and the Eckart powders.
And yes, I have used it. The site is located at www.StarMolecule.com Its a very dark powder, and has a lot of kick, however... it is not good for powder coating, or custom flake paints (at least not what they are selling on there), they had other types, that I do not see at the moment.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
