A convection compatible closed cassette and method are described herein where the closed cassette is used to heat treat (compact) one or more glass sheets in a uniform manner and in a clean environment. In the preferred embodiment, the closed cassette includes multiple enclosed sections that are supported by a mounting structure in a manner where there is an open passageway between the major surfaces of each pair of the supported enclosed sections. And, each enclosed section is designed to hold and support multiple glass sheets in a manner where there is a space between the major surfaces of each pair of the supported glass sheets. In operation, the closed cassette is placed into an oven (e.g., lehr, batch kiln) so that hot/cold unfiltered air can flow across the major surfaces of each enclosed section and uniformly heat/cool the enclosed glass sheets. |
