PROBLEM TO BE SOLVED: To provide multipurpose reinforced glass tableware which has high rigidity and heat resistance, and can suppress the scattering of glass pieces at breakage, in the tableware formed with a compression stress layer on a surface of glass which is formed of soda lime glass.SOLUTION: Multipurpose reinforced glass tableware 10 comprises: a tableware main body 20 which has a surface layer formed with a compression stress layer in a range that a compression stress value which is cooled and reinforced by applying cooling air to a surface of glass formed of soda lime glass is 24 to 64 MPa, is molded so that a mouth part 21 side becomes large and a bottom part 23 side becomes small, and formed into such a shape that the same shape glass can be multiply laminated; a flange part 30 formed at an external periphery of the mouth part 21 of the tableware main body 20; a plurality of protection ribs 40 formed at an external periphery of a lower flank part 23A of the tableware main body 20; and at least three holding protrusions 50 formed outside the bottom part 23 of the tableware main body 20. |
