Chinese Vermilion, which is so rich in color as to command five or six times the price of the European product, appears to be prepared in the ordinary way, leaving nothing to account for the superior brilliancy of shade except the sunnier climate. By careful selection, the finest portions arc collected, and, if necessary, ground and washed several times. In making the artificial product, one part of sulphur and four of mercury are introduced into an earthen pot, to which an iron cover is luted and bound with wire the pot with its contents is then placed in a fire of dried camel s dung. After sublimation, the cover is removed aud the pot broken, and the purest of the sublimate picked out from, the less-colored product, ground very fine, and the powder sifted into a large vessel of watar. When the red product lias subsided, the supernatant... 

Smoke shells and rockets are used to produce smoke clouds for military signaling and, in daylight fireworks, for ornamental effects. The shell case or rocket head is filled with a fine powder of the desired color, which powdered material need not necessarily be one which will tolerate heat, and this is dispersed in the form of a colored cloud by the explosion of a small bag of gunpowder placed as near to its center as may be. Artificial vermilion (red), ultramarine (blue), Paris green, chrome yellow, chalk, and ivory black are among the materials which have been used, but almost any material which has a bright color when powdered and which does not cake together may be employed. 

Between the years 1400 and 1890 the reds that artists used were extracted from plants, such as madder, or from crushed insects, such as the scale insect Dactylopius coccus, or were of mineral origin, such as cinnabar (mercury sulfide, HgS) which could be ground to a powder to produce the pigment vermilion which was much used in antiquity, or red iron oxide (Fe203) which was used by the Neolithic cave painters, or minium (red lead, Pb304). 

Dissolve 16 parts gum-arabic in the least possible quantity of water, and mix with it 9 parts phosphorus iu powder (see No. 4338) then add 14 parts nitre (saltpetre), and 16 parts of either vermilion (red sulphuret of mercury), or binoxide (black oxide) of manganese, aud form the whole into a paste. Dip the matches into this pasto, and then let them dry. When quite dry they are to be dipped into a very dilute copal or lac varnish, and again dried by this means they are less likely to suffer from damp weather.

Properties of the Vermilion of Antimony.—The vermilion of antimony is in the state of a very fine powder, without taste or smell, and is insoluble in water, alcohol, or essential oils. It is but little acted upon by the weak acids, even when concentrated, or by the powerful inorganic acids which have been diluted with water. It stands the latter acids better than the ordinary sulphide of antimony. Concentrated and hot hydrochloric acid dissolves it, with formation of sulphuretted hydrogen and chloride of antimony. Nitric acid oxidises it, with the production of sulphuric and antimonic acids. The vermilion of antimony is not sensibly acted upon by ammonia or the alkaline carbonates on the other hand, the powerful caustic alkalies, such as potash, soda, baryta, strontia, and lime, decompose it and form combinations which are colourless, or nearly so. The colour is therefore destroyed consequently this pigment should not be mixed with alkaline substances. A high temperature blackens it, and should the heat be such as to melt it, it becomes ordinary svilphide of antimony. 

Occurs naturally, as cinnabar, and is the chief ore of mercury. Is formed by fusing sulphur with 6 parts of mercury, and suhliming or by pouring a solution of corrosive sublimate into an excess of hydrosulphuret of ammonia, when a black powder fallsj which is to be dried and sublimed. When sublimed, the bisulphuret forms a dark red crystalline mass, called cinnabar, which, when finely powdered, acquires a very fine red colour, and becomes vermilion. 

Real Powder is a secret name of cinnabar. In the Liquid Pearl, 1.4b, the ingredient of this elixir is called Vermilion Child zhu er), an abbreviated form of Vermilion Child Who Descends on the Mound (jiangling zhu er), which the Shiyao erya (Synonymic Dictionary of the Materia Medica ... 

Although it is better to colour the soap in the ordinary way before powdering it, the colouring matter may, if preferred, be introduced into the mortar when the soap is about half reduced to powder, and then worked up with the soap until thorougily incorporated. Por rose-colour, about one drachm of vermilion to each pound of soap should be used. Por yellow, from one to two drachms of finely-powdered gamboge. Other shades of colour, however, may be given if desired. 

Powdered soaps, named after their respective perfumes, are much esteemed as shaving soaps by the fastidious and perhaps the so-called rose soap, perfumed with oil of rose and tinted by vermilion, may be considered one of the most delicate preparations, provided that it has been made from a good white tallow soap free from cocoa-nut oil.
