| Uneven Surface | Inconsistencies in the glass texture due to improper mold release or inadequate heating. |
| Mold Sticking | Glass adhering to the mold, often due to insufficient mold release agents. |
| Incomplete Casting | Sections of the glass not filling the mold properly, leading to gaps or voids in the finished product. |
Troubleshooting common mold issues
Pitting
To combat pitting, consider the following:
- Ensure proper venting in the kiln to prevent trapped gases.
- Select quality glass compatible with your desired results.
- Reduce the firing rate of your kiln to minimize stress on the glass.
Crazing
For crazing, follow these tips:
- Use compatible glass types and ensure proper annealing temperatures.
- Allow for a controlled cooling process to minimize thermal shock.
- Avoid rapid temperature changes during firing and cooling.
Uneven Surface
To prevent an uneven surface:
- Ensure the mold is level before pouring glass.
- Use adequate mold release to aid in even glass flow.
- Consider preheating the mold to allow for better glass expansion.
Mold Sticking
If you encounter mold sticking, try these suggestions:
- Select a high-quality mold release agent and apply it thoroughly.
- Explore different mold materials that are less prone to sticking.
- Keep the mold clean and free from residue.
Incomplete Casting
For addressing incomplete casting issues:
- Inspect molds for any blockages or imperfections before use.
- Pour glass slowly to encourage even filling of the mold.
- Consider adjusting the viscosity of your glass materials if necessary.
