An apparatus for manufacturing vacuum insulation glass is provided. The apparatus for manufacturing the vacuum insulation glass includes a cap frit disposed on an exhaust hole, and an exhaust finishing frit provided on a bottom surface of the cap frit and including a frit formed of a glass material. The exhaust finishing frit is dispensed, in the paste form, to the cap frit such that the exhaust finishing frit is easily aligned with the cap frit.

Apparatus for manufacturing vacuum glass

Provided is a glass composition comprising a glass frit containing PO, BaO, ZnO, group I-based oxide and group II-based oxide, wherein the POis contained in an amount of 20 wt % to 55 wt % based on a total weight of the glass frit, wherein each of the BaO and ZnO is contained in an amount of 2 to 30% by weight based on the total weight of the glass frit, wherein the group I-based oxide is contained in an amount of 5 to 20% by weight based on the total weight of the glass frit, wherein the group II-based oxide is contained in an amount of 1 to 15% by weight based on the total weight of the glass frit.

Glass composition and cooking appliance

A glass composition formed of a glass frit including PO, SiO, BO, AlO, ZrOand group I-based oxide, wherein POis contained in an amount of 20 wt % to 40 wt % based on a total weight of the glass frit, SiOis contained in an amount of to wt % to 30 wt % based on the total weight of the glass frit, BOis contained in an amount of 3 wt % to 20 wt % based on the total weight of the glass frit, AlOis contained in an amount of 7 to 24 wt % based on the total weight of the glass frit, ZrOis contained in an amount of 1 wt % to 7 wt % based on the total weight of the glass frit, and the group I-based oxide is contained in an amount of 7 wt % to 28 wt % based on the total weight of the glass frit.
