## What is the maximum temperature at which a glass can be quenched in ice water without breaking.

(OP)
Hello! I have a problem and someone might have a solution.
I am working on thermal shock and tempering of ceramics ware. I need to know the mathematical equation at which glass can be heated so that after quenching it may not fracture. It would be easy for me to theoretically calculate quenching temperatures.

### RE: What is the maximum temperature at which a glass can be quenched in ice water without breaking.

There is a thermal shock test that is based on this. You quench from various temperatures and look for a drop in flexure strength. I am sorry but I don't remember the official name of the test.

Try ASTM C1525 Standard Test Method for Determination of Thermal Shock Resistance for Advanced Ceramics by Water Quenching.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
eBook - Efficient and Effective Production Support with 3D Printed Jigs and Fixtures
Jigs and fixtures offer manufacturers a reliable process for delivering accurate, high-quality outcomes, whether for a specific part or feature, or for consistency across multiples of parts. Although the methodologies and materials for producing jigs and fixtures have evolved beyond the conventional metal tooling of years past, their position as a manufacturing staple remains constant due to the benefits they offer.
