Abstract

PURPOSE:To enable a plurality of glass products to be produced economically through relatively reduced operations by forming a cutting pattern on a sheet of glass so that a plurality of products can be cut off from the sheet. CONSTITUTION:The subject product of a glass sheet is produced by forming a cutting pattern 3 on a glass sheet of a certain thickness 1 so that a plurality of products may be cut off. The pattern is selected from those by which the parts of the product 2 can be easily cut off by breaking glass with hands or mechanically easily. For example, the pattern is formed by the groove 5 along the shape of the product in a half-round section and connecting lobs 6.
