    5. POLOLARISCOPE CHECK
    To test the balance of compressive stress and tensile stress depends on the color what you see.

    6. FRAGMENTATION CHECK
    Apply tape (adhesive film)on the convex (front) surface of the lid, domed side upward, break it with a hammer broken 5X5cm measuring range , number of particles (fragments) counted should be at least 40,
