Glass is an amorphous solid made from natural raw materials limestone, soda ash and sand by melting at very high temperatures. At high temperatures glass is liquid in nature and it becomes solid upon cooling. Glass is hard, brittle, transparent or translucent when in solid state. Glass is used in many aspects of daily life as industrial or household objects or their parts. Glass samples are subjected to various destructive and non-destructive testing to assess their end-use suitability.


Introduction to Glass Testing

Glass is an inorganic solid material, usually transparent or translucent in appearance and hard, brittle, and impervious to other natural elements. Items made of glass find use in a range of applications across various industrial and household purposes. Depending on the function, style, and design required, glass is often molded, blown, cut, or pressed in different shapes and sizes. Performance of glass as a raw material and glass products is evaluated to check their suitability in end-use conditions as per the standards defined.

Glass Testing Methodologies

Glass testing standards support material science labs, material processing businesses, product makers, and other users of glass and glass products in their appropriate fabrication and treatment methods to assure excellent quality and craftsmanship toward safe use. Following are the common tests done for glass and glass items-
  • Determination of Internal Pressure Strength of Glass Containers
  • Determination of thermal Shock Resistance of Glass Containers
  • Polariscopic Examination of Glass Containers
  • Determination of Sulfide Resistance of Ceramic Decorations on Glass
  • Determination of Strength of Glass by Flexure
  • Determination of Softening Point of Glass
  • Determination of Annealing Point and Strain Point of Glass by Beam Bending
  • Determination of Density of Glass by Buoyancy
These and other test methods evaluate the performance of glass and glass products to effects of weathering, volatile fogging and other environmental exposures, including extreme temperature variations, ultraviolet radiation, and changes in humidity.
MaTestLab Inc. offers accessible, quick, and affordable material testing, product testing, and failure analysis services. We support your on-demand testing and expert consultation needs with the help of our extensive network of material testing laboratories situated in the US and other parts of the world.
We offer destructive and non-destructive tests over a range of mechanical, electrical, chemical, thermal, optical, corrosion, radiation, and biological testing methodologies defined by ASTM, ISO and other organizations.
We help you evaluate and ensure your product quality and performance with standard and custom-made testing solutions. All the tests are done at well-equipped testing laboratories using standard testing methods for best output and satisfaction.
Failure analysis ensures high levels of quality in every manufacturing process. We help you with getting the best failure or root cause analysis to determine the cause of the failure. The results help you identify means to prevent failure recurrences.
