How can you dissolve sulfur ore to a viscous liquid state and yellow-red color?
Answer from: Andrey Ilyin:
Sharing my experience...
One of the components in sulfur ore is sulfur (5-10%).
Therefore, it is necessary to dissolve sulfur ore in the same way as sulfur.
This is done by acid. In the reaction of sulfur and acid there is a stickiness and a red-yellow color.
