Soda-lime Glass

Soda-lime glass is the most prevalent type of glass. Soda-lime glass is prepared by melting the raw materials, such as soda, lime, silica, alumina, and small quantities of fining agents in a glass furnace at temperatures locally up to 1675°C. Soda-lime sheet glass is made by floating molten glass on a bed of molten tin. This method gives the sheet uniform thickness and very flat surfaces. Soda-lime glass is the base material for most clear, colored and patterned glass types.  

Features

  • Can be chemically tempered to increase mechanical strength
  • Can be heat strengthened or heat tempered to increase thermal shock resistance and mechanical strength
  • Can be bent, laminated, machined, optically coated, chemically etched, sandblasted or colored
  • Good flatness and surface quality due to float process
  • Economically Priced

Normal Service: No breakage from excessive thermal shock is assumed. Extreme Limits:  The glass will be very vulnerable to thermal shock.  Recommendations in this range are based on mechanical stability considerations only.  Tests should be made before adopting final designs. Thermal Shock: Based on plunging sample into cold water after oven heating. Resistance of 97F means no breakage if heated to 147F and plunged into water at 50F. Tempered samples have over twice the resistance of annealed glass. Temperature Gradient: The temperature differential between two surfaces of a tube or constrained plate that will cause a tensile stress of 1000 psi on the cooler surface.
