Bullion, whether it is Au, Ag, Pt or whatever, is always measured in TROY ounces (ozt.).
One TROY ounce = 31.1 gm.
Yes indeed. So, starting over:
* We begin with $695USD for 20 grams of 47.8% gold-containing Chloroauric acid (HAuCl4) (from China) which contains approximately 10 grams of gold metal.
*
1 Troy oz of gold costs $1394USD (at one moment in time today). 1 oz ~ 31.1 gms (thank you RickinWI). 10 gms of Au would (in a linear world) cost 10/31.1 x 1394 = $448 compared to $695 for 20 grams of Chinese HAuCl4 (10 gms of gold
~ $2161USD/oz gold).
* Americans (not us Canadians) can buy Salt Lake Metals Gold Chloride Solution (1%) costing $100 for 1 gm of gold metal content. This translates to $100/1gm x 31.1 gms/oz =
$3110USD/oz of gold. This is 2.2-times the cost of gold in today's market (for an ounce).
* Compare this with China's gold cost (via HAuCl4): $695/10gms x 31.1gms/oz = $2161/oz. This is ~31% less than Salt Lake Metals Gold chloride.
* Compare this with the cost of HAuCl4 (50%) from Sigma Aldrich (
https://www.sigmaaldrich.com/catalog/product/aldrich/50790?lang=en®ion=CA ) at $924CAD/5gms or $712USD/5gm * 4 = $2848 for the original required 20 grams of HAuCl4.
Does anyone have a better deal for Gold chloride than the Chinese (for Canadians without a business + business address + a great scientific/institutional excuse for the acquisition of this product)?
Of course, we have to deal with the issue of trust here as well. Who knows what standards are employed by various Chinese companies dealing with International customers ordering small quantities (one COA attached), but, I've done this once before with good results. It's either roll the dice again or stick with electrolysis which, as I recall, Kephra stated produces colloidal gold of lesser quality than the HAuCl4 recipe. Electrolysis does seem to be ~35% less expensive though (1394/2161) - 1 x -100)).
Thoughts?
