And, with it's greater surface area exposed to an explosive pressure wave, I'd be worried about cracking that fragile floor pan of the base chamber.
And this is the part that I can't wrap my feeble mind around. Both coals can be highly explosive given the right conditions. The coal I'm using right now works beautiful, as long as I leave some glowing coals to burn off the volatiles. The only time I get a puffback, is if I get the coals really, really hot before adding fresh.
I'm guessing it's a matter of degree of volatiles volume changes the level of risk.
Getting a fire really hot before adding more coal is exactly what some anthracite users have learned works best to get a faster recovery. So, is it quicker recovery ? Or ....QUICK, take cover.
