Sunstone is also known as "heliolite" and more commonly "aventurescent feldspar." It is cut into cabochons, beads, and small sculptures. The most transparent pieces are used to produce faceted stones. Sunstone is popular with innovative jewelry designers and is especially popular in the geographic areas where it is commercially mined.
Quartz itself comes in many varieties, according to its color and microstructure. ... Silica sand also consists of other fine particles of rock and mineral.

The same mold can produce parts with different wall thicknesses just by increasing or decreasing the charge weight. So for example, if the part requires 42 lbs of resin to create a part with a wall thickness of 3/16" it would need approx. 2 cu.ft. of interior volume, but the mold only has 1.375 cu.ft. of interior volume.

The muscovite mica is die cut to the sizes offered. The thickness of the mica sheets varies between 0.18 - 0.25mm (0.007 - 0.01") which yields much thinner, uniform sheets. Cleaving can also be achieved by placing a double coated piece of tape onto the mica surface and gently pulling off the mica layer starting on one edge of the mica.

Quartz is one of the hardest minerals on Earth. Because of its strength and abundance, quartz is a popular and reliable choice for countertops. Quartz countertops are sometimes referred to as "engineered" or "man-made," but quartz is in fact a natural stone. The amount of natural quartz in a slab depends on the quartz manufacturer.
As the number indicating the mesh size increases, the size of the openings and thus the size of particles captured by the screen decreases. Higher mesh numbers = smaller particle sizes. It is very important to remember that mesh size is not a precise measurement of the mesh opening size. This is because screens

Quartz Quartz is a man-made engineered stone surface formed by combining 90% ground quartz (a natural hard mineral) with 8-10% resins, polymers, and pigments. This forms a very hard granite-like surface. How it looks depends on how the quartz is ground: coarsely-ground quartz produces a flecked appearance while finely-ground quartz produces a smooth look.
