Recycled Glass

[Decofusion]

I am interested in the recycling of glass.  In particular wine/beer bottles.  I have seen breadboards/cheese boards made from bottles – from what I understand the bottles are broken into pieces then placed into a mould.  I’m guessing the mould would be 4 pieces of fibre board placed together to make a square.  Once fused the piece is then well sanded – the result looking like marble.  Has anyone experimented with this method? I would like to know what kind of temp I would need to use.
