As the acetic acid is added you will begin to see a red-brown solid form and fall to the bottom. This is the Kermes Mineral. Allow the solids to settle, then decant the clear liquid from the top and save it aside. This liquid contains mostly sodium acetate which can be recovered for use in the acetate work. Its previous association with antimony makes it even more valuable. 

The most common way of producing the Regulus begins with stibnite or the Kermes mineral.

Kermes Mineral. Dissolve 2H troy ounces carbonate of soda in 16 pints boiling water add 1 troy ounce finely powdered sulpburet of antimony, and boil for on hour. Filter rapidly into "a warm earthen vessel, cover closely and cool slowly. After 24 hours decant the fluid, drain the precipitate on a filter, wash it w ith cold water (previously boiled), and dry without heat. Keep in a well-stopped bottle, protected from the light. (C. S, P/(.) This is the oxysuljihuret of rtntimofty. 

Carbonates of the alkalies act like the alkaline hydrate they give rise to the formation of the oxide and sulphides of the alkalies, with evolution of carbonic acid secondary actions produce siilphantimon-ites, antimonites, and antimony sulphide. The solution of the sulphide is never complete, even when it is heated and, according to Terreil, carbonate of potassium does not help it. This has been demonsti-ated by Weppen and affirmed by Terreil. When a solution of sodium carbonate, to which the sulphide has been added, is being cooled, there are formed the sulphide, neutral and acid antimonites of sodium, and antimonious acid, constituting what is called Kermes mineral. ... 

C. J. Geoffroy mentioned as a volatile salt the crystals deposited from essential oils. He published on antimony, tartar emetic, and kermes mineral. He showed that soap is readily soluble in hot alcohol, the liquid on coohng setting to a clear jelly, and that the oil set free from the soap (really oleic acid) by the action of acids is more soluble in alcohol than the original oil. In his paper on Prussian blue he argued that the soufre animal of the organic material sets free iron in a fine state of division which, when mixed with the sulphurous principle and absorbent earth, exhibits a blue colour. (Until recently, the blue colour of ultramarine was ascribed to finely-divided sulphur.) He translated the work on assaying of Christian Carl Schindler. ... 

This compound is found in nature as red antimony and when sesqnisulphuret of antimony is boiled with potash, and an acid added to the filtered liquid, a reddish orange precipitate is formed, which is often oxysulphuret although it may be obtained nearly free from oxide, and is then hydrated sesqnisulphuret. This is the substance so long known as mineral kermes and it is the form in which sulphuret of antimony is chiefly used in medicine on the Continent. In this country we use the precipitated ses-quisulphuret.

Kermesite is an antimony oxide sulfide mineral of red colour. Gross morphology is of acicular or fibrous crystals which radiate out from a centre. The name derives from kermes q.v, a term more recently reserved for the insect red dye derived from Kermococcus illicis), which in turn comes from the Persian qurmizq - crimson . In older chemistry this referred to red amorphous antimony trisulfide, often mixed with antimony trioxide.
