WebApr 7, 2024 · IJAGS reports glass science and engineering research aimed at meeting the challenges of using glass in consumer, commercial and industrial applications. Abstract … WebReplacing Na 2 O with B 2 O 3 produces a borosilicate glass that expands less on heating. Adding PbO produces lead glasses that are ideally suited for high-quality optical glass. The most common way of preparing a glass is to heat the mixture of sand and modifiers until it melts, and then cool it quickly so that it solidifies to produce a glass. lampe h9b
