Measure the dimensions of the bonded glass. Find a glass, metal or ceramic container that you can completely immerse the glass in.
Pour 4 cups of acetone with 6 cups of water into the container. Mix the acetone with a glass stirrer. You'll need to use glass, metal or ceramic components as acetone dissolves plastic.
Place the bonded glass into the container. Make sure to immerse the bonded glass completely in the solution.
Soak the bonded glass in the solution for eight hours. The epoxy in between the bonded glass will start to dissolve during the soaking process.
Remove the bonded glass when the epoxy is fully dissolved. At this point, the glass sheets can be separated from each other. Rinse the glass pieces in distilled water to remove any remaining acetone solution.
