This is because it belongs to the cubic group of minerals where the refractive index of light is common in all orientation.
The velocity of light is the same in all directions.
The metals, properties of which are the same when taken through any direction.. As in, if u consider quartz, it'd have different attributes when u conduct tests in different directions.. If there is any metal in which the properties r the same for all directions, it is called an isotropic metal!
Bakelite is optically isotropic.
For example the crystallized quartz.

Under normal conditions of temperature and pressure the mineral Quartz is a crystalline solid.
Formula for the volume Expansion for a solid is αV=1VdVdT and Isotropic materials is αV=3αL.
see if it has any solid quartz in it . Quartz makes it worth nothing.

"Smelt Quartz" is commonly sold as a variety of quartz, especially from many eBay vendors. "Smelt Quartz" is not quartz at all -- it is common glass, which is made from melting quartz in the presence another compound (called a flux) which lowers the melting temperature. Glass is not crystalline, whereas quartz and other minerals (with few exceptions) are crystalline. Most people can't tell the difference, but glass is optically isotropic (doesn't polarize light) whereas quartz is anisotropic (polarizes light). Glass also has a lower density, which you might be able to detect by its heft, and "smelt quartz" usually has unnatural looking streaky patches in it."
you stupid there is no answer for the second part you fool.

Bakelite is optically isotropic.
Aluminium and steel are e.g. of isotropic materials.

Solid surface is a man-made material composed of acrylic and polyester resins, while granite is a natural stone. Solid surface is non-porous and more uniform in color and pattern, while granite is porous and has natural variations in color and pattern. Granite is more durable and heat-resistant than solid surface.
For example the crystallized quartz.
