摘要
A method of finishing an edge of a sheet glass is disclosed. The method includes a first grinding step for grinding an edge of a sheet glass so as to provide the edge with an outwardly convex curved shape, and a finishing step for finishing a bordering portion which has been formed by the first grinding step between the curved edge and each flat side face of the sheet glass, so as to provide this bordering portion with a greater smoothness than smoothness provided by the first grinding step. A heat-tempered sheet glass using the method and a fire-resistant construction material using this heat-tempered sheet glass are also disclosed.
