Hi Daemonfly,
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.
Thanks,
Steve Pituch
