It takes its name from the Greek f3apvs (heavy) on account of its presence in barytes or heavy spar which was first investigated in 1602 by V.
Much of the raw material for this industry, such as ball, flint, and spar clays and kaolin, is imported from other states.
Being very brittle, the spar is rather difficult to work on the lathe, and is often toughened by means of resin.
In the midst of this consternation, Queequeg dropped deftly to his knees, and crawling under the path of the boom, whipped hold of a rope, secured one end to the bulwarks, and then flinging the other like a lasso, caught it round the boom as it swept over his head, and at the next jerk, the spar was that way trapped, and all was safe.

That this is not a necessary characteristic of light was discovered by Christian Huygens, who found that, whereas a stream of sunlight in traversing a rhomb of spar in any but one direction always gives rise to two streams of equal brightness, each of these emergent streams is divided by a second rhomb into two portions having a relative intensity dependent upon the position with respect to one another of the principal planes of the faces of entry into the rhombs - the planes through the axes of the crystals perpendicular to the refracting surfaces.
She found herself remembering what his body looked like when he stripped down to spar with her, how the muscular length of him felt against her own body when they were locked in combat.
Calcium metasilicate, CaSiO 3, occurs in nature as monoclinic crystals known as tabular spar or wollastonite; it may be prepared artificially from solutions of calcium chloride and sodium silicate.
In both cases the spar evolves free fluorine, which ozonizes the air.
