Some highly filled mineral compounds can cause abrasive wear in injection molds or extruders, depending on the filler, the filler’s loading, and the processing conditions and metals used to make the tooling. Some minerals are harder and more abrasive than others. On the Mohs scale of mineral...

Minerals are "crystalline." In other words, they have an ordered atomic structure. In contrast, mineraloids are "amorphous." This means that their internal atomic structure is not ordered. Without the ordered atomic structure, mineraloids never produce well-formed crystals. They also do not exhib...
Feldspar is associated with the granites and pegmatites and is one of the most common and abundant minerals found in the earth's crust. It is used in many types glass and ceramics. Feldspar's principal purpose is to lower the melting temperature of the mixture of materials which is added. ...
Most pieces of agate do not have "eyes," so stones that do have them are especially prized by collectors. Natural glasses: Obsidian is a natural glass formed during an eruption of silica-rich magma. Shown here are Apache tears, mahogany obsidian, and snowflake obsidian. Minerals Amazonite (...
"Polished cabochons of cinnabar are sometimes seen in jewelry." Now That's Interesting Cinnabar is one of the few minerals that is sectile, meaning you can cut it into thin pieces with a knife. Gold is another sectile mineral, while pyrite, aka "fool's gold," is not and will crumble...

In terms of utility, minerals are crucial in various industries as raw materials (e.g., quartz in glass making, lithium in batteries). In contrast, ceramics are widely used in industries like construction (tiles, bricks), electronics (insulators, substrates), and even in biomedical applications...
