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.
