I agree silicone does not melt. not even if it burns.
I assume you are right, there are 2 liquids present. one beeing water or
acid, the other beeing some more oily liquid, maybe it is silicone oil, i
have read RTV silicone can be made more liquid with silicone oil (not sure
if this is true).
It would then be like a frying pan, the hot oil and water.

Also note soetimes i hear sizzling with a normal paper/toner/PCB transfer,
but much much less. I expect a tiny amount of water or something.


I would not attept the acrylic, because these _DO_ melt, in the fuser too
i would expect.
