On Assignment-Show Modern Fire Assay of Gold
News Break? I was asked for some images of a process called “fire assay”, which is used to find the precise amount of gold in a sample. It’s an old process. Involves chemistry at high temperatures to render down to pure gold. Compare sample weight vs pure gold weight. That happens in an oven at 2000F. I happen to have a friend that does exactly that at her small biz with her husband.
Now there is a couple ways to show that process. Maybe like the eye sees it before one looks away of necessity. Yellow and indistinct. Kinda stuck with that in the lab shot. I happen to like to take it down a notch light wise. Let the detail shine and rich color convey the heat.
