To melt a wine bottle into a cheese board, rinse it, insert a wire loop into the neck, lay the bottle on a kiln shelf, fire it, and remove the cooled bottle. This 24-hour procedure requires a sink, a towel, a kiln, a kiln shelf, kiln shelf paper, wire, wire cutters and heat-safe gloves.
- Prepare the bottle and kiln shelf
Line a kiln shelf with kiln shelf paper. Rinse the exterior of the wine bottle, dry it thoroughly, and lay it on the kiln shelf.
- Load and heat the kiln
Load the kiln, turn it on, and set the temperature increase speed to 500 degrees per hour. Set the temperature to 500 degrees Fahrenheit, and maintain that temperature for 12 minutes.
- Increase the temperature
Raise the temperature to 750 degrees Fahrenheit, and keep it there for 12 minutes. Raise the temperature to 1,000 degrees, hold it for 10 minutes, and then increase the temperature to 1,300 degrees. Keep the kiln at 1,300 degrees for 20 minutes, reduce the temperature increase speed to 250 degrees per hour, raise the temperature to 1,475 degrees, and hold it for 10 minutes. Lower the temperature to 1,100 degrees and maintain it for one hour. Reduce the heat to 970 degrees, hold it for 30 minutes, and then reduce the temperature to 750 degrees. Keep the kiln at this temperature for 20 minutes, then turn it off.
- Cool the kiln
Allow the kiln to gradually return to room temperature. This takes several hours. Keep the kiln door closed until the heat dissipates. Then put on heat-safe gloves, remove the kiln shelf, and inspect the bottle. Discard the kiln shelf paper.
