new process and new apparatus for
cooking, which he gives to the public.
The theory OF it is based upon the non
conducting properties Of certain mate
rails with which the oven may be en-

cooking vessels, safety valve being
provided for the escape of steam. The
heat used is derived from a common
kerosene lamp or gas burner.
