Finishing with Wet/Dry Sandpaper

Wet/dry sandpaper offers an alternative for those who don't want to spend the money on diamond hand pads or cold working equipment.  The sandpaper, which  generally consists of a coating of silicon carbide particles on a waterproof backing, is widely available from hardware, DIY, and woodworking retailers.

One good use of wet/dry sandpaper is to help achieve a smooth matte finish after sandblasting the surface of glass.  Start with 400 grit wet/dry sandpaper and plenty of water.  Place a sponge between your hand and the sandpaper and rub thoroughly across the surface of the glass.  Once the highs and lows of the entire surface have smoothed out, switch to 600 grit and go over the piece again.  The key ingredient in this process is TIME;  it's essential to continue working with the sandpaper until no scratches remain.

For a final finish, fire polish or slump, preferably at a temperature below 1200F/650C.  The low temperature will ensure an even matte finish on the piece.
