How can I achieve a perfect Opaque Paste application?

Avoid impurities or bubbles on the surface of the metal crown by sandblasting, cleaning, and oxidating thoroughly. Sandblast the surface with an appropriate grain size of 110-130𝜇𝑚 using a clean abrasive at a 45° angle, 2-3 bar pressure. Thorough cleaning may be performed using an ultrasonic cleaner with distilled water or steam cleaned.

Drying time must not be too short, and we recommended a drying time that is longer than four minutes. Opaque liquid and Opaque materials must not be contaminated with regular water. Fire with sufficient vacuum conditions, check and adjust the vacuum conditions of the furnace if necessary.
