How to Separate Two Pieces of Glass

Separating two pieces of glass can be a tricky process. The key is to determine the kind of adhesive used to bond the two pieces of glass. Once you have identified the kind of adhesive, you can then use the correct adhesive remover to separate the glass pieces. Soaking the pieces of glass is the easiest way to loosen the adhesive so you can separate the glass.

Craft Glue

Separate two pieces of glued glass with the correct adhesive remover.
  1. Fill a flat container large enough to fit the glass pieces glued together with craft glue in with hot water. Allow the pieces of glass to sit in water for 24 hours.
  2. Replace the water in the container every two hours with hot or near boiling water.
  3. Remove the glass from the water and gently pull the two pieces of glass apart. Wipe the glass with old towels to dry the surface and remove glue residue.

Epoxy Glue

  1. Put on a respirator mask and eye protection. Work in a well-ventilated room away from extreme heat or flame. Use epoxy solvent to loosen glass glued by epoxy. Epoxy solvent is highly flammable, so take care when working with the chemicals.
  2. Fill the large container with epoxy solvent. Soak the glass pieces in the container for 12 to 24 hours.
  3. Remove the glass from the water. Separate the pieces with a putty knife.
  4. Rinse the surface of the glass with water to remove traces of solvent. Dry the glass pieces with an old towel.

Fast Drying Glue

  1. Fill the container with acetone. Place the glass pieces inside the container. Make sure the acetone covers both pieces of glass.
  2. Leave the glass in the acetone for 24 hours.
  3. Remove the glass from the container and gently pull the pieces apart. Wash and dry the glass to remove the acetone and remaining glue reside from the surface of the glass pieces.

Silicone Glue

  1. Fill the container with ethyl alcohol. Put the glass pieces in the alcohol mixture.
  2. Allow the glass to soak inside the container for about 10 minutes.
  3. Pull the silicone glue away from the glass by hand, or use a putty knife to scrape the two pieces of glass apart.
  4. Wash and dry the glass to remove any silicone residue.
