Oil and Colour Chemists' Association

Colour Tolerance

ON February 12, the Physical Society Colour Group held its inaugural meeting at the Regent Street Polytechnic, London. In accepting the responsibility for the formation of this group, the Physical Society hopes to provide a valuable opportunity for people interested in colour, whether as physicists, chemists, dyers, industrialists or otherwise, to meet for their mutual benefit. A number of societies have already agreed to co-operate by becoming founder societies of the group and, in addition to the Physical Society, these include the British Kinematograph Society, the Illuminating Engineering Society, the Institute of Physics, the Royal Photographic Society, the Society of Glass Technology, the Society of Dyers and Colourists, and the Oil and Colour Chemists' Association.

Tung Oil

TUNG oil is an essential raw material of present-day varnish manufacture, and in fact its unique properties render it indispensable for certain types of varnish. Until comparatively recently, China has satisfied the world's demand for tung oil, and will, it is considered, continue to remain the chief source for some years to come. The oil is derived from two species of Aleurites, Fordii and montana, of which the former is the chief source. It was Wilson, a naturalist in western China, who in 1915, after a study of the species of Aleurites, solved the question as to the true origin of tung oil. A. Fordii has its habitat chiefly in western and central China, whilst A. montana is found more to the south. Tung oil, also termed China wood oil, was known outside China about 1760. It was first introduced into the United States in 1896, into Germany in 1897, and soon afterwards into England. Little notice of it was taken commercially in England until after the outbreak of War, when specil water-resisting varnishes were required for aeroplane work. Thereafter, on the recommendation of the Raw Materials Committee of the Imperial Institute, growing experiments (Wilson having stated that he considered the trees could be grown in South Africa, East Africa, Australia, Algeria, and Morocco) were started in India, Ceylon, Malaya, Burma, Kenya, Tanganyika, Hong-Kong, and South Africa. The position of this new industry was first reviewed in a paper prepared by Dr. L. A. Jordan, of the Research Association of British Paint, Colour, and Varnish Manufacturers (Technical Paper, No. 1), published by the Association for private circulation in 1927. The work described proved of such importance and aroused such interest that the paper has been now republished, after a revision, by Dr. Jordan (Journal of the Oil and Colour Chemists Association, Vol. 12, No. 107, May 1929).

(1) The Dyeing of Textile Fibres (2) The Dyeing of Cotton Fabrics (3) Textile Colour Mixing: a Manual intended for the Use of Dyers, Calico Printers and Colour Chemists

(1) MR. R. S. HORSFALL and Mr. L. G. Lawrie, who are members of the staff of the British Dyestuffs Corporation, Ltd., the former being head of the dyehouse department of that firm, are peculiarly well-fitted for the compilation of a book dealing with the dyeing of textile fibres in general. The outlook of the average dyer must be limited largely to the activities within his own dyehouse, so that the types of dyeing upon which he is engaged and in which he is expert eventually become in his eyes the most important. As a result, although fitted to produce a specialised monograph dealing with the sections of the trade upon which he is engaged, lie wou[d be liable to produce an unevenly balanced general book on dyeing. On the other hand, nowhere can such a varied experience of dyeing be gained as in the dyehouse section of a works where colouring matters are manufactured. It is here that colour- ing matters are submitted to the most rigorous examination in order to discover their good qualities or defects, and to elaborate the most suitable methods of application in the case of products of commercial value. Further, the success of a colour works depends to a great extent upon close touch being maintained between the expert staff of its dyehouse section and all types of the colour consuming industries, Consequently, a most varied and evenly balanced experience of dyeing is gained, as is apparent in the book under review.

The Properties of Powders

CONSIDERABLE interest attaches, both on the scientific and on the technical side, to the study of powders which are sufficiently fine to differ markedly in their properties from massive crystals, o while they are sufficiently coarse to differ equally widely from colloidal suspensions. One important property of powders, namely the caking of salts (a phenomenon which was responsible for the disastrous explosion at Oppau), was discussed at a joint meeting of the London Section of the Society of Chemical Industry and of the Faraday Society on March i, 1920. This has now been followed up by a joint meeting of the Faraday Society and the Oil and Colour Chemists' Association, held at Burlington House on March 9 last, when the material presented was sufficiently abundant to call for an adjourned discussion on March 23.

University and Educational Intelligence

LEEDS.—The urgency in the demand for the training of colour chemists and dyers has led to a reorganisation of this department of the university. The newly appointed head of the department is Mr. A. G. Perkin, F.R.S., who is assisted in the theoretical and practical teaching of colour chemistry by Dr. J. B. Oesch, formerly colour chemist in one of the chief Continental factories, whilst that of dyeing is under the special supervision of Mr. G. H. Frank, Mr. P. King, former chemist to Messrs. Courtaulds, Ltd., and Mr. A. E. Woodhead. In addition to systematic instruction in the above branches of technology, opportunities will be afforded to students of hearing special courses of lectures on “Cellulose” by Mr. C. F. Cross, on “The Distillation of Coal Tar” by Mr. H. P. Hird, and on “Colour in its Relation to Constitution” by Prof. E. R. Watson, of Dacca University.
