How to sell used gold?

Hi everyone. I made a ring for my fiance within a few months so i kind of crammed all my focus onto getting a final product.

So i am now stuck with about 16 grams of gold that was melted but never used because of failures or it got stuck to the bottom of the crucible.

While moving the ceramic crucible it fell and busted open. So i decided to only take the pieces that had any metal on them and sort them with the used gold.

What is the best way to take this gold and sell it to make some of my money back?

Some context: i have a furnace, kiln, magnetic tumbler, pickle solution and ultrasonic cleaner in case any of those tools help the process.

Ceramic or graphite crucible

2 Upvotes

I usually use ceramic but due to an increase in humidity of where I live I noticed some things in my studio are not liking the moisture. I have set up a dehumidifier, etc but I am kinda concerned about my ceramic crucible having moisture in it that causes it to crack when I put a flame to it… is graphite a safer option? Usually using it to sand cast with Sterling. Also want to get into casting with bronze. So wondering if I should buy 2 graphite ? Or stick with ceramic?
