LOCK&LOCK endeavors to enhance our position as a global brand to meet the demand of global market that grows every year by building plastic, heat resistant glass and cookware plants in the world including China and Vietnam.
LOCK&LOCK Vung Tau Heat Resistant Glass Plant manufactures 10,000 tons of heat resistant dinnerware annually.
Unlike soda lime glass, Heat resistant glass contains sodium borosilicate(B₂Oз), which can stand the rapid change in temperature and high temperature heat. LOCK&LOCK oven glass can be safely used in diverse cooking environment including microwave, oven or freezer. They not only can stand the hot water disinfection, they can also be washed using dishwashers, dish dryers and steam sterilizers very safely.

Heat resistant glass main process
1. Mixing Materials
4. Fire Polishing
A reason why heat resistant class process is more difficult
Key material of heat resistant glass is sodium borosilicate (B₂Oз) that is strong for a rapid heat change; therefore, the price and production cost is quite high. Its dissolution time is longer as a melting (fusing) point is 1,000℃, which is far higher than general glass or tempered glass (normally 600~700℃). Manufacturing process is also difficult as it has to be put to the leer to gain uniform thermal stability, stay maintaining the high temperature for certain time and slowly cool down.
