What do your researches on Google say ? Its been "possible" for at least 4000 years.

Why don't you answer them yourself. Google and Wikipedia both have information at the basic level you need.

In the glass melting experiments I've been involved in, the usual crucibles are made of SOLID platinum ! A fused silica crucible will work. You need a furnace capable of around 1600 C, though a sodalime glass will melt at about 1500C

Just spent a week in Germany melting glass ! We used Boron Nitride and graphite crucibles for that - and NO oxygen. Some weird high temperature chemistry going on in the furnace atmosphere that I didn't understand.

Ooh that sounds fun. Molten boron is something else again (as I understand it)?

You need to mix sand with other stuff like lime and borax, and you need a serious amount of heat. The other answers are good: this information is searchable (but I'm just going off a big list in my head...)
