New experimenter!

[Nevadayote]

I was researching how to dissolve a mass of borax at the bottom of a crucible when I found a post from this forum. The borax mass is still there and just as stubborn, but I'm here now and hope to learn about this whole thing from others.

There is much I stil need to do to get set up semi-properly (new bench dedicated to recovery and refining, fume hood). The forum seems quite active, so I'm glad I found it!

Welcome to us.
Borax will dissolve in hot water or dilute Sulfuric given time.

Anyway since you are here and plan to refine we want you to study the content these links:

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

Welcome.

Borax needs to be thinned with the proper flux. if your crucible has more life in it I suggest you read this thread and thin your slag before pouring it into a cone mold.

I use crucibles for melting, and smelting. A melt dish is for metal powders, melting with a torch, usually. For sealing a melt dish, with Borax, direct the flame in a circular pattern to heat the ceramic evenly. It must get hot enough that when a pinch of Borax is dropped into the melt dish or crucible, it melts almost instantly. Add just enough to coat the inside surface lightly and evenly. Dropping a mass into the bottom, hoping it will melt, then you can roll it around to coat, can lead to a headache/learning curve.
