Bubble Squeeze

A bubble squeeze is used to help eliminate bubbles from forming in your glass piece. This process is used when fusing several pieces of glass together. Holding your glass at a set temperature will allow your glass to equalize out in temperature.

Slowly heat up your glass. Once your glass has reached around 1000 degrees Fahrenheit, soak the piece for about 15 to 30 minutes. This will allow the layers to relax and equalize in temperature. Then increase the heating process at about 50 degrees Fahrenheit per hour. Once you reach around 1220 degrees Fahrenheit, put in a half an hour soak. This will allow time for the air between your pieces to escape before the edges seal and trap the bubbles in the glass. If your arranged pieces are prone to trapping air, soak the item for two or three hours. Once you have finished your squeeze, continue firing your piece to either a tack fuse of full fuse. Bubbles can’t be removed once they are trapped inside your glass.

Check on the internet to see what temperature your particular type of glass begins to move. When figuring out what you want to make, factor in the size, color and design of your project. Always check the layout of your piece and try to set it up so that air won’t get trapped between two pieces of glass. You can also use frit, or small pieces of glass sandwiched between your glass. These pieces will take longer to heat up and melt than the middle of your piece, allowing the air to escape.
