clay holds heat well like cast iron.
I have a lodge brand, enamel lined cast iron pot or "caldaro ".
It makes the best home made chicken soup. provides even heat distribution which allows me to control the temperature carefully . I usually cook the soup 6-7 hours on low. Then I turn the flame off, go to bed and the next morning the pot is still lukewarm. put in refrigerator and I have soup for days.
I bet the LA CHAMBA would have similar results . probably slightly better, but I wonder about durability if they break easily? I want to start with a comal, for cooking tortillas, roasting Chile's tomatoes, onions, garlic ect. If it doesn't break after heavy use, I would buy a clay caldaro
