Question

Why are cooking utensils blackened at the bottom?

Answer 1

The bottom parts of the cooking utensils are all painted black so that maximum heat can be absorbed into the foods that are cooked in those utensils.

Thus, the cooking becomes much speedier with a utensil with blackened lower part.

However, the upper part is kept in shining state so that minimum heat is lost from this shiny surface, maintaining the heat inside the utensil that is received from the oven.

Usually, the cooking utensils are made of metals that are best conductors of heat, like aluminum and steel that originally shine brightly if not painted.
