how to do a fire assay

So what is fire assay, exactly? Fire assay is a specific process used by scientists and researchers to determine the content of gold, silver, or other precious metals in a sample. This method had been used thousands, thousands -- maybe even hundreds -- of years. That being said, it is still one of the best and most accurate methods to test for these precious metals. Just think of it as a really powerful detective that shows what’s inside of rocks or other materials!

Step 1 — Prepare the Sample First, you need the sample that you would like to test. It could be a rock or dirt. You will smash this sample into tiny particles. So you add some chemicals to the mix. It smooths your path and gets you higher quality results.

Step-by-Step Instructions for Performing a Fire Assay

Melt the Sample: The next step is to place the sample into a furnace to melt it. A furnace is a special type of oven that can get very hot. You heat the sample until it melts and transforms into a liquid. This is very important because you need the sample in a liquid state to be able to see the metals.

There’s now metal: Once the sample is melted, you’re going to add some other chemicals. All these chemicals isolate the metal of interest from the other components of the sample. Describe how it is like using a magnet to extract metal pieces from sand!
