Bake-out

Bake-out, in several areas of technology and fabrication, and in building construction, refers to the process of using high heat temperature (heat), and possibly vacuum, to remove volatile compounds from materials and objects before placing them into situations where the slow release of the same volatile compounds would contaminate the contents of a container or vessel, spoil a vacuum, or cause discomfort (odor or irritation) or illness.
