A method of and apparatus for treating articles with heat and pressure is disclosed. Included in the apparatus is a furnace in which the articles are to be treated. The articles are placed in the furnace and, the furnace is evacuated, then filled with an inert gas the pressure and temperature of which is raised to predetermined levels. These predetermined levels are maintained for a period of time sufficient to effect the treatment, and, thereafter the inert gas is circulated to promote cooling of the gas and reduce the cooling time of the furnace and the article treated.
