Specific gravity Test for Gold and Quartz Specimens:
Figure out how much gold is in a quartz gold specimen. The simplest way to test specific gravity is weigh the quartz gold specimen in “air” and multiply the weight by 1.9. Then weigh the quartz gold specimen fully submerged in “distilled water” and multiply that weight by 3.1. Minus the wet figure from the dry figure and you will get a fairly accurate specific gravity for that specimen!! You can then approximate how much pure gold is in the piece by using the numbers above. (this formula assumes relatively pure quartz with no pyrites or other country rock attached and 85% pure gold in the specimen)
These following numbers are specific gravity of certain materials:
I HAVE A 15OZ LARGE QUARTZ SPECIMEN WOULD LIKE TO KNW HOW MUCH GOLD IT CONTAINS
Need help I'm finding all kinds quartz and I'm finding it hard to determine value, and marketing it as well if any interest please help if not thanks for what I have already learned from this site thanks again for your contribution to the regular guys trying to be! What was, Is,And will be,in any light ! Stay True thanks!
I about to do a blog post on quartz, stay tuned!
