Tempered glass is a safety glass produced by controlled thermal or chemical tempering — heating annealed glass to approximately 620°C and then rapidly quenching with cold air jets. This creates a surface compression layer balanced by a central tensile zone — making tempered glass 4–5× stronger than annealed glass of equivalent thickness and causing it to fragment into small, relatively harmless granular pieces (rather than sharp, dangerous shards) if broken.
It is a precision-cut glass sheet used in laboratories for sample preparation, observation, material testing, and experimental procedures. Made from high-quality transparent glass, it provides excellent optical clarity, chemical resistance, and dimensional stability, making it suitable for research, quality control, and analytical applications.
