Repair Techniques for Glass Molds
Repairing your glass molds might seem daunting, but with the right techniques, you can restore them effectively. Here are methods for the common types of damage:
Chips
To repair chips, use epoxy or a specialized mold repair material. Follow these steps:

- Mix the epoxy according to the manufacturer's instructions.
- Apply the epoxy to the chipped area, smoothing it out to match the mold's contour.
- Allow it to cure fully before using the mold again.
Crazing
For crazed molds, a gentle sanding may help. Follow these steps:
- Use fine-grit sandpaper to lightly sand the crazed area.
- Wipe with a damp cloth to remove dust.
- Apply a newly formulated mold release compound to protect against future crazing.
Rust
Remove rust using the following method:
- Create a paste using baking soda and water.
- Apply the paste to the rusted area and scrub gently with a soft cloth.
- Rinse thoroughly and dry to prevent moisture retention.
Warping
Addressing warping can be tricky. Here’s what you can do:
- Inspect for any signs of flexibility in the mold.
