Because we had to answer it on contest.
And it's interesting.

I think it is a Priestley experiment, heating mercury till it gets oxidized, heating oxide till it decomposes.

Yum mercury vapor, haha.

from wiki
HgO decomposes on exposure to light, on heating above 500°C producing highly toxic fumes including mercury and oxygen, which increases fire hazard

I don't think OP is going to repeat the experiment, more like just theoretical approach.
