Optical fiber is a term for any sort of plastic or glass conduit meant to transport light. The principles behind it are actually quite old, but in recent years it has become an incredibly important technology, as communications infrastructure has begun to use this fiber to transmit data at extremely high rates.ptical fiber is a term for any sort of plastic or glass conduit meant to transport light.

Kirinite knife handles. Kirinite is a really interesting new handle material that has emerged in the past ten years or so, and made a big splash in the world of knife handles and gun grips.Itâs made from âa toughened acrylic with very thin colored strands of poly paper swirled through the mix.â And the results are things like this:nother plus in the aesthetic side of things, as far as kirinite goes, is that it takes a fantastic polish without becoming slick and hard to grip. To get that smooth of a finish on a wood handle you have to put some type of finish on it to fill the grains, which is a lot of hassle.
Rhyolite is an extrusive igneous rock with a very high silica content. It is usually pink or gray in color with grains so small that they are difficult to observe without a hand lens.Rhyolite is made up of quartz, plagioclase and sanidine, with minor amounts of hornblende and biotite.Trapped gases often produce vugs in the rock. These often contain crystals, opal or glassy material. Many rhyolites form from granitic magma that has partially cooled in the subsurface.When these magmas erupt, a rock with two grain sizes can form. The large crystals that formed beneath the surface are called phenocrysts and the small crystals formed at the surface are called groundmass.Rhyolite usually forms in continental or continent-margin volcanic eruptions where granitic magma reaches the surface. Rhyolite is rarely produced at oceanic eruptions.hyolite is made up of quartz, plagioclase and sanidine, with minor amounts of hornblende and biotite. Trapped gases often produce vugs in the rock.
