Any of several chemically and literally related aluminum silicate nutrients, common in igneous and metamorphic stones, characteristically splitting into versatile sheets found in insulation and electric gear.
some of a small grouping of hydrous aluminosilicate nutrients characterized by highly perfect cleavage, in order that they readily isolate into very thin leaves, just about elastic.
title of several nutrients characterized by highly perfect cleavage, so that they easily isolate into extremely thin leaves, just about elastic. They vary widely in structure, and vary in shade from pale brown or yellow to green or black. The clear forms are utilized in lanterns, the doorways of stoves, etc., being popularly called isinglass. Formerly called also cat-silver, and glimmer.
A crumb; a bit.
One of a group of minerals all of which are characterized by their very perfect bassal cleavage, in consequence of which they can be separated easily into extremely thin, tough, and usually elastic laminæ.
into the planning of kaolin for use in make of porcelain, one of several second group of networks through which a combination of liquid and suspended clay beaten up by the liquid from broken clay-bearing rock is gradually passed to search for the deposition of flakes of mica as well as other foreign substances, and so to cleanse the clay, which is eventually allowed to subside in some pits or tanks.
A prefix frequently used in lithology once the rock involved includes just about mica besides the various other typical constituents. Hence, mica-syenite, a rock differing hardly any from ordinary syenite; mica-trap, almost the same as minette, etc.
some of numerous nutrients composed of hydrous silicates of aluminum or potassium etc. that crystallize in kinds that allow perfect cleavage into extremely slim leaves; used as dielectrics for their resistance to electricity
