The Glass-Lining Process
The quality of glass-lining is as much about the enamel formula as it is about the application process. De Dietrich manufactures its enamel in-house to ensure:
- Perfect homogeneity & purity for consistent performance
- Multi-layer spray & firing technique to achieve precise thickness
- Strict quality control (spark testing, thickness measurement, visual inspection)
- A smooth, polished surface free from defects or irregularities
By mastering both enamel production & application, we guarantee the highest reliability on the market.
