Abstract

The author conducted a series of tests to examine the usefulness of crazed glass as an indicator of abnormal fire behavior. Despite widely held beliefs and widely published statements that crazing of glass is a result of exposure to rapidly increasing temperature, the test results show that glass will not craze, except when its temperature is rapidly decreased. A finding of crazed glass in a fire scene has no special meaning regarding the temperatures to which the glass was exposed.
