How Do You Melt Glass at Home?


Quick Answer

Use a kiln to melt glass at home. As of 2010, kilns are available for between $4,000 and $10,000. Clean and dry the glass items that you plan to melt, and put them in a thick garbage bag. Put the first bag inside a second bag, and smash the glass into small pieces using a hammer. Place the larger pieces into a mold, and arrange them so that there are as few gaps as possible.

Use smaller pieces of glass, and the dust that is left behind, to fill any small gaps in the mold. When it is full, put the mold in the kiln, and slowly increase the temperature. Raise the temperature by 500 degrees Fahrenheit each hour until it reaches 1000 degrees Fahrenheit, and leave it so that the glass can reach the same temperature. Increase the temperature again to 1500 degrees Fahrenheit, and wait for the glass to reach the desired consistency.

When the glass is at the right consistency, turn the kiln down to 1100 degrees Fahrenheit. When the kiln reaches that temperature, turn it off, and let it cool slowly. When the kiln reaches 100 degrees Fahrenheit, remove the mold and glass. Let the glass cool to room temperature before removing the mold.
