Sulfur of Antimony

This is how I did it. There are quite some other ways out there. When reading B.V. this should be the right one, IF the vinegar is sharpened with Sal Ammoniak. It is not 100% clear in the triumphal chariot. However, if you don't sharpen it like this, nothing will happen.

Remember the hint with the nail.

Did you use the regulus of antimony or stibnite?
What kind of experiments have you done before doing glasses?
