from Germany• Thickness of glaze depends on the final application (storage

medium) and varies between 0.25 and 0.45 mm• Firing is in a continuous tunnel oven at 800 – 900 degreesC

• Joint between the enamel and the steel is in a molten state, ensuring perfect and total adhesion between these materials

• Testing/Quality control: thickness, 1500V holiday tests, … • Packaging• Shipping
