Garnet

Etymology The word garnet comes from the 14th‑century Middle English word gernet, meaning ''dark red'' is borrowed from Old French grenate from Latin granatus, from granum (''grain, seed''). This is possibly a reference to mela granatum or even pomum granatum (''pomegranate'', Punica granatum), a plant whose fruits contain abundant and vivid red seed covers (), which are similar in shape, size ...

Principles of tubular free abrasive drilling

Pressing abrasive grains against the granite surface, it neither protrudes nor creases when it shifts from a harder spot to a softer one and back. In ancient Egypt When holes drilled in granite blocks at doors or gates were used as hubs for hinge pins, their inner walls were smoothed—perhaps, prior to actual usage.

What Is Granite And How Is It Formed?

Formally, granite is a plutonic rock that is composed of between 10 to 50% quartz (typically semi-transparent white) and 65 to 90% total feldspar (typically a pinkish or white hue). Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock.
