Barytes is mined in the north of England and in County Cork.
Although celestine much resemblesbarytes in its physical properties, having for example the same degree of hardness (3), it is less dense, its specific gravity being 3.
Celestine crystallizes in the orthorhombic system, being isomorphous with barytes (q.

Barytes Carbonates of barytes(A) Aërated or effervescent heavy earth.
Barytes Nitrat of barytes Nitre, with a base of heavy earth.
Barytes is still of more difficult solution; it dissolves only in 900 times its weight of water: but it is much more soluble in the state of crystals.
It so strongly resemblesbarytes in its properties, and is so sparingly found in nature, and of so little use in the arts, that it will not be necessary to enter into any particulars respecting it.
Strontia differs from barytesin being infusible, much less soluble, of a different form, weaker in its affinities, and not poisonous.
One of the characters of the salts of strontia, is, that they give a red flame to burning bodies; whereas the salts of barytes or of lime, used in the same manner, communicate a yellow flame.
By evaporation, the chlorate of barytes will crystallize in fine rhomboidal prisms.
Yet an extensive literature on barytes and barytes mining had been published by the Germans, showing exactly how German barytes was ground.
Again, it was admitted that German barytes was better ground than English.
They had not found a barytes miner in England who owned a microscope.
The supernatant liquor will, if the chromate be pure, afford now no precipitate with the nitrates of barytes or silver; whence the absence of the sulphates and muriates may be inferred.
A precipitate of the yellow chromate of barytes falls, which being washed and dried would amount to 130 parts.
The quantity of sulphur is always so small, that it can scarcely be ascertained by the weight of the precipitate of sulphate of barytes from the solution of the iron in nitro-muriatic acid.
Magnesia dissolved in much smaller quantity, and barytesseemed to decompose the sugar entirely.
Neither can there remain any doubt concerning the existence of valuable deposites of manganese, lead, crome and iron, in your immediate vicinity, to which I think we are authorized to add zinc, barytes and marble.
The machine product is too obviously regular and lacks the silvery brightness produced in old pressed glass by the use of barytes and the artistic technique of the hand made mold.
The New England Glass Company omitted this barytes from its glass with resulting dullness.
The barytes will combine with the sulphuric acid and the compound (sulphate of barytes) will fall to the bottom, leaving a pure solution of soda in the water.
The reason of this, according to Berthollet, is not that barytes has a stronger affinity for sulphuric acid than soda has; but because sulphate of barytes is insoluble in water.
Lime is a compound of calcium and oxygen, magnesia of magnesium and oxygen, barytes of barium and oxygen, and strontian of strontium and oxygen.
I may mention the process of Fourcroy and Vauquelin for obtaining pure barytes, by exposing nitrate of barytes to a red heat, as a good one.
In this case the barytes has seized all the sulphuric acid, and displaced the soda.
Potash would be disengaged from sulphuric acid by barytes and strontian, but not by soda, lime, and magnesia.
This led Lavoisier to conclude, as Bergman had done before him, that Barytes is a metallic oxide.
There are some other processes which I myself prefer to either of these, because I find them equally easy, and still less expensive than either carbonate of barytes or oxide of lead.
Barytes also burns when exposed to this violent heat.
In the year 1793 he published a comparative set of experiments on the nature of carbonates of barytes and strontian; showing that their bases are two different earths, and not the same, as had been hitherto supposed in Germany.
This is partly obviated by recovering the barytes in the state of carbonate; and this, in general, may be done, without much loss.
Barytes has proved its usefulness as a constituent of a combination type of paint, but it should not be used alone.
Illustration: Microscopic View of Barytesunder Polarized Light] A slide of paint containing these re-enforcing pigments is prepared in the usual manner.
Illustration: Section Barytes Film] A view of these sections of paint films under the microscope gave to the operator a better idea of the structure of a paint than had ever been afforded heretofore.
It takes its name from the Greek [Greek: barus] (heavy) on account of its presence in barytes or heavy spar which was first investigated in 1602 by V.
Crystals of barytes may be transparent and colourless, or white and opaque, or of a yellow, brown, bluish or greenish colour.
Illustration] Crystals of barytes are orthorhombic and isomorphous with the strontium and lead sulphates (celestite and anglesite); they are usually very perfectly developed and present great variety of form.
Artificially prepared crystals of barytes may be obtained by allowing a solution of a soluble barium salt to diffuse slowly into a solution of a soluble sulphate.
The "crested" or "cock's comb" barytes occurs as rounded aggregations of thin lamellar crystals.
The barytes is remarkably pure, and after grinding is sold in large quantities.
At Wotherton, two miles from Chirbury, is a fine barytes lode which has been worked for more than 60 years, at first as an open mine, and subsequently by means of a shaft.
Many sulphates are important minerals, prominent among these being gypsum (calcium sulphate) and barytes (barium sulphate).
The ore lies in this marly clay, and is often accompanied by sulphate of barytes and calcareous spar.
Yellow mamillary quartz, incrusted with sulphate ofbarytes and haematitic iron.
The carbonate of barytes is eminently poisonous; but we have never heard that the sulphate is so.
Radiated quartz, incrusted with sulphate of barytes and iron.
The carbonate of barytes is eminently poisonous; but we have never heard that the sulphate is so.
The loss of weight indicates the quantity of carbonate of barytes which the precipitate contained.
Thomson remarks that "no other precipitate can well be confounded with it, except sulphate of barytes; and there is no probability of the presence of barytes existing in common water.
The nitrate of barytes should be well dried and powdered; it should then be mixed with the other ingredients, all finely pulverized, and the whole triturated until perfectly blended together.
Take of flowers of sulphur thirteen drachms, of nitrate of barytes seventy-seven drachms, of oxymuriate of potash five, of metallic arsenic two, of charcoal three.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "barytes" in a variety of sentences. We hope that you will now be able to make sentences using this word.
