I experience this during parting the inquarted silver.
The initial nitric boils go well, but during the final boils I experience acid popping(exploding at times) out of my beaker.
I have the beaker covered with a watch glass, but I have cases where acid pops out of the beaker(along with some gold at times).
The boils go as follows, I place the beaker on the hot plate and after some time the dilute acid starts boiling, after some time as the acid is boiling the beakers starts popping.
What's different between the initial and the final boils is i progressively reduce the amount of nitric acid solution(nitric acid + distilled water) I add each time but I make sure the gold is covered to the top.
I have also had instances of popping during the final boil in distilled water.
I'm pretty sure I am not the first one experiencing it.
Is this because of excessive heating....?
Is the reduced amount of acid solution the problem...?(I doubt because I've also had popping during distilled water boils.)
Seems pretty dangerous to me, would somebody please care to explain why such popping happens and how to avoid it in the first place.
Thanks Regards.
