LOCK&LOCK Vung Tau Heat Resistant Glass Plant
manufactures 10,000 tons of heat resistant
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
LOCK&LOCK HEAT-RESISTANT GLASS FACTORY IN VIETNAM This is LOCK&LOCK Heat-Resistant Glass factory co-build with increased design and construction company for glass melting process to meet the soaring demands for safer heat-resistant glassware worldwide. LOCK&LOCK decided to launch its own production facility. Vietnam, especially, offers an exquisite advantage in producing glassware products. It will therefore, provide the necessary impetus in expanding LOCKk&LOCK's consumer base into European and North American markets. It will also spur the development of other businesses that will have various industrial applications.
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.
