TECHNICAL CHEMISTRY. 1017 T e c h n i c a 1 C h e m i s t r g. Extraction of Iodine and Bromine from Kelp. By R. GAL- L O WAY (Chem. News, xxxviii, 146).-The author discusses the dis- advantages of Wollaston’s process for the extraction of iodine and bromine from kelp, and proposes t o use chlorine as a liberator of these bodies instead of manganese dioxide and sulphuric acid. The process proposed by the author is as follows :-After extracting the potassium chloride, the kelp liquor is exactly neutralised with sulphuric acid, and in a small sample the amount of chlorine water necessary to form iodine pentachloride is determined. To the bulk of the liquor one-sixth of the relative quantity of chlorine water which was required by the small sample is added. This liberates the iodine, which is removed, and the amount of chlorine-water for the liberation of the bromine determined, and one-half the relative quantity is added, which liberates the bromine.I f the solution should be rendered too dilute by precipitating all the iodine and bromine with chlorine water, a portion might be precipitated by the gas and the remainder with the solution. L. T. 0’s. New Mineral White Pigment. By T. L. PHI P s o N (Chem. Nezus, xxxviii, 105) .-Whilst experimenting on some of the artificial sili- cates which are remarkable for their brilliant white colour, the author learnt that Mr. T. GriBths, of Liverpool, had obtained a new mineral white, the basis of which was sulphide of zinc ; and on submitting this new product to a careful examination, the author found that it not only surpassed the old zinc white, but that it was superior in every respect to carbonate of lead itself.It is obtained by precipitating either chloride or sulphate of zinc by means of a soluble sulphide- sodium, barium, and calcium sulphides have all been used for this purpose-and precautions are taken lest any iron that may be contained in small quantities as an impurity in the zinc solution, should be pre- cipitated with the sulphide of zinc. The precipitate, being collected and dried, is transferred to a furnace, where it is calcined, and after careful stirring i t is raked out, while quite hot, into vats of cold water, when it is levigated, and afterwards collected and dried. The result is a white pigment of exquisite beauty ; its covering power when mixed with oil is p e s t e r than that of any substance hitherto dis- covered, being about 25 per cent.higher in this respect than that of the same weight of pure carbonate of lead. According to the author’s analysis, this new product consists of an oxysulphide of zinc, the COIN- position of which varies somewhat according to the duration of the calcination and the exact degree of heat attained. The best product appears to correspond very glosely with the composition 5Zns $ ZnO. D. B. Toughening of Glass. (DirzgZ, polyt. J., ccxxix, 57--GG).-The discovery of toughened glass in 1875 by R. de 1s Bastie, raised great expectations ; but these have not as yet been realised, the properties of toughened glass riot having caused it to supersede ordinary glass.1018 ABSTRACTS OF CHEMICAL PAPERS.It is well known that toughencd glass is obtained by a process of sudden cooling, which may be effected in various ways, and by the use of different cooling agents. The resulting change is of a purely physical nature, the chemical composition of the glass remaining un- altered. The mddenness with which the softened mass passes over into the solid condition gives rise to a state of molecular tension in glass, which gives the latter its speci6c properties. The chemical and physical properties of glass used for toughening purposes are of great importance. Badly fused or ill-refined glass always cracks in the cooling bath, whilst the presence of basic or acid con- stituents facilitates devitriflcation and hinders tthe success of the toughening process.The temperature of the cooling bath varies with the fusing point of the glass to be toughened, and also depends on the outer form and tbe thickness of the sides of the vessel under operation. The cooling effect of a toughening bath is regulated bF the specific: conducting power of heat of the substance formiiig the bath, good conductors requiring higher temperatures than bad con- ductors. Such baths may consist of fatty substances, oil, glycerin, paraffin, hydrocarbons, concentrated saline solutions, and readily fusible metallic alloys. Water cannot be employed ; all baths must be absolutely free from tlhe latter. Fat or oil baths are not only very expensive, but also give rise to the danger of fire, sudden alteration of temperature, and other defects.Steam has the property common to fat baths of being applicable at different temperatures, and has the advantage that such baths retain the same temperature during the whole process. The cooling action of steam baths on red-hot glass may be regulated, apart from a higher or lower temperature, by using superheated, saturated, or supersaturated steam. Solid bodies have also been used for toughening purposes. The resistance of glass toughened by oil is said to be equal to 601 kilos., toughened by means of steam, 700 to 1,100 kilos., whilst ordinary glass possesses a tenacity of 220 kilos. per square centi- meter. Bottles of toughened glass stand a pressure of 52 atmospheres, ordinary glass bottles only 39 atmospheres. It also bears sndden a1 terations of temperature without cracking. When ordinary glass is, after fusion, cooled slowly and investigated optically, no important appearances are observable, a fact which proves that no irregularity in the structure has taken place.Toughened glass, on the other hand, gives coloured lines, which vary in character and intensity with the form, the thickness, and the toughness of the glass. With regard to the various theories proposed to account for the toughening, the author explains that owing to incorrect observations the opinion was held for some time that toughened glass had a higher specific gravity thaii ccnimon glass. Hence it was thought that but. the sudden change from the liquid to the solid state the expansion of the glass was hindc rcd, the product becoming specifically heavier.On this fact a,ll other characteristic properties were based. Recent investigations, however, have shown that the specific gravity of toughened glass is less than that of slowly cooled glass. A toughened glass plate which resists the fall of heavy weights,TECHXICAL CHEMISTRY. 1019 provided they drop on the centre of the plate, breaks very easily by ZL mere blow with an instrnment against its sides or edges. When the edge of an untoughened glass is struck against some object, the former often breaks only partially and is not altogether useless ; toughened glass, however, is completely destroyed under the same conditions. Por this reason the manufacture of toughened glass decanters, beakers, or bottles cannot be recommended.Tn conclusion it is mentioned that although 110 satisfactory observa- tions have been made regarding the duration of the toughness of glass, it is nevertheless probable that toughened glass loses its peculiar pro- perties in the course of time. Electro-deposition of +Cobalt. By A. GA I F F F: ( C m p f . wad., lxxxvii, 100) .-Cobalt as deposited by the electric current is preferable to iron and nickel as a protective surface to clichck, &c., as it does not oxidise like iron, and when necessary it can be readily dissolved by dilute acids, which do not attack the copper under-surface. For the clectro-deposition of cobalt on copper the author employed a neutral solution of the double sulphate of cobalt and ammonium. The posi- live electrode is connected with a platinum or preferably with a cobalt lhte, and by passing a regular current through the solution for four hours an adhering and regular deposit of white metallic cobalt, 0.025 m.m.in thickness, was obtained. Becquerel (ibid., p. 130) claims to have already described a method similar to the above in a paper published in 1862 (Gowzpt. rend., lv, 18). A. J. C. Sulphur and Phosphorus in Iron. By S. KERN (Chem.

Influence of Heat on the Structure of Steel. By W MET- U A Lip (Dingl. polyt. ,J., ccxxix, 92--93).-1n relation t o Mattl-iieu Williams’s contribatious to the theory of steel (ibid., ccxxviii, 543), t8he author gives the following data, in regard to the hardeniiig of steel. Any difference in temperature which suffices to effect a change in the colour of t’he metal produces a difference in the grain, and Analysis :- Si02.A1-0,. FeO. Cu20. CaO. K20, Nn2O. D. R.1020 ABSTRACTS OF CHEMICAL PAPERS. latter ca,uses an interior expansion, which is accompanied frequently by the formation of cracks in the metal. If the temperature is suffi- ciently high to form a grain which is coarser than that possessed by the original substance, the hardened metal becomes brittle, is liable to crack, and shows but little resistance at its edges. I f the temperature on the other hand is merely high enough to harden the metal without altering the grain, the steel has been refined in a satisfactory manner. It is stronger than the original metal, its edges being tough and cut- ting.Such temperatwes are the most suitable for the preparation of boring or cutting instruments. It is known that hardened steel may be annealed by heating it, and then cooling it slowly; but the proauct never possesses the original firmness. It will be seen from the above that every instru- ment made of steel, if i t is first heated and then cooled even with the utmost care, is liable to have cracks in it or suffer alteration of form, if its separate parts have not been previously exposed to a regular tem- perature. Moreover, every instrument of steel will be rendered useless for the purpose for which it was intended if it has not been heated to the corresponding temperature. Langley’s experiments coincide with those of the author, and are worthy of notice, a8 they give some interesting relations regarding the proportions of the densities of hardened and unhardened steel.It is shown that (1) the rolling process increases the specific gravity ; that (2) the hardening operations decrease the same ; and that (3) the rc- fining methods do not increase the specific gravity. Mending Platinum Crucibles. By T. G A R s I 1) E ( C ~ L News, xxxviii, 65) .-The author found that platinum being “ weldable,” crucibles of this nietal might be repaired in this manner. A mould was made of plaster of Paris, which served admirably as an anvil. A piece of moderately-thin platinum foil was laid over the hole, and the flame of a blowpipe directed upon the spot, the part where the hole was having previously been rubbed with sea-sand until perfectly clean and bright.On gently tapping with a pair of scissors, which served as a hammer, the twa pieces of platinum united perfectly and made a neat joint. Although the dish has been used for all kinds of purposes since, the union is as good as ever. Platinum wires are very easily joined in this manner. D. B. D.
