" Chemistry was transformed by glass perhaps more than any other discipline. You only have to go to any chemistry lab to see that the transparency and inertness of the material make it perfect for mixing chemicals and monitoring what they do. Before the glass test tube was born, chemical reactions were performed in opaque beakers, so it was hard to see what was happening. With glass, and especially with a new glass called Pyrex that was immune to thermal shock, chemistry as a systematic discipline really got going. "
