See the eighth entry from the top "Approximate weights and densities". As soon as we get more information from other people the sooner we can upgrade the information. Do you have any weights and densities you can give us? We need to have the samples for one level tablespoon (14.79 ml volume) weighed on an accurate scale.
Unfortunately I can't afford to go out and buy a sample of everything.
My digital scale came with a 50 g and 100 g weight. Yes if you could carefully measure the chemicals several times it would be appreciated. We are looking for the weights of chemicals in a level tablespoon, meaning you need to level the chemicals with a straight edge before weighing. We also need a description of the chemical as to the amount of grainularity (fine powder, like sugar, etc), and a decription of the source (Greg Watson, Walmart brand, etc). We have found quite a variance in densities and granularity with some chemicals.
