▎ 摘　　要

NOVELTY - Apparatus 10 comprises multiple side portions spaced apart from each other. The multiple heat supply portions 20 are set on each of side portions. The adjacent side portions 30 adjacent to each other are set to face each other. The glass is allowed to be set between adjacent side portions. USE - Apparatus used for manufacturing glass article. ADVANTAGE - The apparatus improves strength, meltability and ion exchange performance, enhances chipping resistance, and reduces power consumption and occurrence of cracks. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a method for manufacturing glass article, which involves: a. molding glass; b. strengthening molded glass; c. heat-treating strengthened glass using glass article manufacturing apparatus; 2. a glass article, which comprises first surface, second surface opposite to first surface, first compressive region extending from first surface to point at first compression depth, second compressive region extending from second surface to point at second compression depth, and tensile region set between first compressive region and second compressive region, where glass transition temperature of glass article is higher than glass transition temperature of glass article heat-treated at heating rate of 10-30 K/minute; 3. a display device, which comprises display panel including multiple pixels, cover window set on display panel, transparent bonding layer set between display panel and cover window, where cover window comprises first surface, second surface opposite to first surface, first compressive region extending from first surface to point at first compression depth, second compressive region extending from second surface to point at second compression depth, and tensile region set between first compressive region and second compressive region, where glass transition temperature of cover window is higher than glass transition temperature of glass article heat-treated at heating rate of 10-30 K/minute. DESCRIPTION OF DRAWING(S) - The drawing shows cross-sectional view of apparatus. Apparatus (10) Heat supply portions (20) Adjacent side portions (30) Support portion (40) Glass article (100)
