Well, I flashed up the Neolithic kono yesterday, but the results were disappointing.
The sides of the kono became very hot to the touch; 80-90 degrees, according to my infrared gun. The heat was leaking away through the perlcrete like there was no tomorrow. It's not that good an insulator.
Hay tried to cook some sausages in a pan on the griddle, but eventually had to place the pan directly on the coals. It didn't help that there was a fair bit of wind. Admittedly there wasn't a lot of charcoal, but certainly more than I'd used in the MkII on Saturday.
All in all, when all's said and done, at the end of the day, in conclusion, in the final analysis and to coin a phrase, the firebrick kono was a resounding success, whereas the Neolithic one needs further refinement. It could simply be that the air holes aren't large enough or that it's too deep (charcoal BBQs are usually much shallower), but it's fine as a firepit, leaving much to be desired as a device for proper cooking.
The base can easily be raised with some firebrick or the addition of a layer of fire cement, but that wouldn't cure the heat leakage through the sides and lining the inside sides isn't really an option. It would also increase the weight considerably and it weighs a ton already.
Handles are a must for moving it while it's on, whereas the MkII is easily moved by virtue of being much cooler on the outside, even though hotter inside.
