Opal is made of silica, but it technically is not a mineral.
Opal is a mineraloid gel. It is made, oddly enough, almost entirely of opal. It is also completely free of birefringence, and has virtually no pleochroism. Opal is basically silica. Saying opal is made of opal is like saying quartz is made of quartz, or tiger eye is made of tiger eye. It's the unique structure of the silica that makes it become opal. The Japanese have made a nice man made opal using silica and zirconium oxide. Si02nH20
An Ethiopian opal is an opal-CT, whereas an Australian opal is an opal-A. The Ethiopian opal is made up of leptospheres, instead of small amorphous silica spheres like the Australian opal.
Yes. Silica is the primary component of most types of glass.
Opal is not a mineral, but a silica gel.
Opal is made of silica, but it technically is not a mineral.
Opal ia a hydrated silica mineral.
No. Opal is a mixture of two compounds: silica and water.
No. Opal is an amorphous hydrated form of silica.
The scientific name for opal is hydrated amorphous silica.
yes it is
That is the correct spelling of "opal" (semi-precious stone, hydrated silica).

No, it's actually a form of silica.

Glass is silica dioxide. It is made by melting silica sand.
