Glass production is required massive energy especially in melting processes required 70 - 80
percent of energy . In glass production, batch is absorbed about 75 to 90 percent of total amount
of heat during the first hour , which means batch is strongly effect on energy required. Now a
day energy cost is rising and this is a major problem effecting to glass industry. Almost glass
productions in Thailand are using soda-lime silicate glass produced from sand (SiO2), soda ash
(Na2CO3), and dolomite (CaMg(CO3)2)) adding with alumina (Al2O3). They are usually used in
many products such as tableware, sheet glass, container, etc.
