In Italy wood fired ovens are
known as Forno a legna.
Two types of ovens are available
they are either black or white - this simply
refers to the inside colour of the
ovens when you are cooking with them.
In a white oven the fire is in a separate
compartment and this keeps the oven white.
However when you cook in a black oven
the fire is in the same space as the food
you are cooking.
Masonry Oven is actually the correct
term to describe pizza and bread ovens,
and they can be built with any materials
that can stand high heats.
