Observation Applying the porcelain:-

• The entire surface to be built up with the porcelain powder must be sandblasted thoroughly. The oxide firing should be carried out in vacuum. After firing, sandblast again with 110 μm grit at a pressure of 2 bars. BERYLLIUM DISADVANTAGES
• Beryllium vapors are carcinogenic and hence lab technicians are prone to severe diseases. (Reference-World at work Dental laboratory technicians, N Torbica and S Krstev Occup Environ Med. 2006 Feb; 63(2) 145-148.)
• Prolong release of beryllium from ceramic alloy causes fibrosis of lungs in patients.(Reference-OSHA Beryllium Health Effects March 29, 2016)
