Opal ia a hydrated silica mineral.
Opal is not magnetic. It is a mineraloid made primarily of silica and water, and its chemical composition does not contain any magnetic minerals. As a result, opal does not exhibit magnetic properties and will not be attracted to magnets.
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
Opal is a hydrated amorphous silicate.
Opal is a form of silica, amorphous and hydrated: SiO2.nH2O.
It is an imitation opal made of glass that is red-orange in color.
I think they were called "Opal Fruits." Opal fruits is the answer. The ad jingle was ''Opal Fruits, made to make your mouth water''.
What is it
No, opal is not quartz. While both are considered silicate minerals, opal is a mineraloid that lacks a crystalline structure, whereas quartz is a crystalline mineral with a defined chemical composition of silicon dioxide (SiO2). Opal is primarily composed of hydrated silica and can form in various colors and patterns, making it distinct from quartz.
Opal is a heterogeneous mixture because it is made up of different components, such as silica and water, that are not uniformly distributed throughout the material. This gives opal its unique play-of-color appearance.
What is it
Opals are a mined substance that can be found in fissures in rock. It is then processed, cleaned up and cut down to make different types of jewelry. This is how opal ware is made.
A created opal is a type of synthetic opal that is made in a laboratory. It is created using a combination of silica spheres and a polymer resin material to mimic the appearance of natural opal. Created opals can display similar color play and patterns to genuine opals.
