Ahem! It is much safer doing the hotwater bath!
I had a friend who did the same as you, ....left his ball on the hearth to go answer his phone, and when he came back, the entire side of his ball, where the oil was oozing out........was on fire!
Totally destroyed a two-week oil Columbia Chaos, which at the time was his favorite piece!
Better keep an eye on it!

Duct tape is like 'The Force'. It has a light side and a dark side, but it still holds the universe together.
