I am not sure exactly how this thing works but if you don't put the Cascade in there it will not even hardly warm up. The Cascade (I think it may be the borax), creates some kind of chemical reaction, and it takes a little while but it will get quite hot and bubbly after a while.
Again if you don't put the Cascade in there, no action.
I found that out the hard way
My Brother in law said the instructions were in the box when he let me borrow it, but turned out he had mis placed them somewhere, so I was sort of on my own. Then I found my way to their website and got some help.
Anyway, after I got the Cascade in there, it worked great.
Here is what it looks like after it starts cooking...
Not too bad for your first attempt at \"skull Boiling\".
I noticed that the skull appears to be all intact when you took it out of the boiling pot. But after spraying it off with the hose, it's missing the \"Premaxilla\"(Bone that should extend out past the Nasal Cavity).
After cleaning more than 400 skulls over the past 25 years, I found that when boiling skulls, if you add Too Much Sal Soda(in your case Cascade detergent), it softens up the tissue holding the Skull Plates together and some of the bones start to fall off. But they can be epoxied back on.
I remember my first boiled Deer Skull back 25 years ago looked alot like yours does.
Here's the Beetle Cleaned skull showing the \"Premaxilla Bone\" still intact.(The bone that extends past the nasal cavity).
