Good Stuff To Know
I figured out how to calculate how much gold is in a specimen with quartz.
I found this video which explains how to measure the specimen in water.

Then the formula is pretty easy once you know the dry and wet weights of the specimen:
W = wet specimen (weight when suspended in water as per the video)
D = dry specimen on scale
Just plug in your 2 values in this formula:
(W x 3.07) - (D x 1.91) = wt of gold in quartz/gold specimen
I use grams but you can use ounce or grains, works the same. The 3.07 and 1.91 values are derived from the
specific gravity of gold and quartz in a longer formula. I looked it all up to prove it really works at
