His write-up gives a basic introduction to glassmaking and shows the difference between using sand alone, and using sodium carbonate to reduce the melting point. He produces a few brittle barely ...

But that doesn’t mean that Glass is totally sustainable. Melting old glass needs loads of heat and melting sand for new glass needs even more! And right now, that causes carbon emissions.

The crystal structure of silicates is disrupted by sodium, calcium, and aluminum, lowering the melting point and viscosity of soda-lime glass. Source: Mrmw, CC0. Glass made from pure silica sand ...

“Glass is obtained by melting sand at 1500 degrees Celsius in a masonry (brick) oven, “ said Ahmed Nwailati, owner of glassmaking workshop in the handicrafts market in Damascus. To those ...
