Handbook of Opal Mineral Care in the Right Way
# # Opal Mineral Care Guide in the Right Way
Mineralogically, opal is classified as an amorphous mineral, with no clear crystal structure; the main element is a small spherical, orderly-lined silica, with the chemical formula $SiO _ 2 imes nH _ 2O $representing silica hydration; opal needs more meticulous care than anything else.
# # # 1.Mineralogical causes that make opal fragile
The low stiffness (5.5-6 .5) makes opal scratchy and easy to chip. Also, sudden temperature changes can cause cracks that cannot be repaired.
# # # 2.Correct Opal Mineral Cleaning Principle
Cleaning depends on the type of opal:
* * * Solid Opal: * * Use warm water and soft soap, wash gently.
* * * Opal Assembly: * * Do not soak in water and use dry cloth to wipe
# # # 3.Opal ore preservation is the right way
It should be stored in a velvet lining box or suede bag. Avoid storing in a hygroscopic safe.
# # # 4.Caution to wear
Choose to make a pendant or earring. Reduce the risk of breakage. Make sure to bury safely.
