Quote:Do you have a jeweler's scale? A plated
SBA will be a few tenths or hundredths of a gram heavier than a sac.
A few tenths or hundredths of a gram is meaningless when you don't know what it weighed before it was plated. The tolerance for a Sac is 8.1 grams +/- .3 grams. So even if you get a weight of 8.45 grams it it plated or just a slightly overweight planchet? If you get 8.2 is it plated or just a normal, within tolerance, weight planchet?
