OILS AND VARNISHES 93 



in the dark — a property of very doubtful value, and one not to 

 be easily taken advantage of 



Emerald Green is too " rank " a colour to be used by the 

 unskilled, but is valuable sometimes, and, indeed, not to be 

 replaced by any combination of pigments ; it, however, unites 

 with certain reds to form lovely greys of great tone-value. 



Indian Red is another " rank " but useful colour, to be 

 used with care as being surcharged with iron. 



Terra Rosa is a finer preparation of Light Red, which it 

 supersedes. 



Zinc White has less body, and is more difficult to work 

 with in oil than Flake White, although the fine powder is 

 indispensable in flower-tinting, as it is, in its well-known form 

 of Chinese White, for flower-painting. 



Oxford Ochre replaces Yellow Ochre, of which it is a finer 

 preparation. 



The makers of the fine powder - colours will supply half 

 ounces of any of those marked one shilling per ounce, 

 and as small a quantity as an eighth of an ounce of all the 

 extra colours ; one or two of the best makers, however, supply 

 all colours in bottles of varying sizes, but at a uniform price of 

 sixpence each. 



OILS AND VARNISHES 



These, if wanted for any of the finer pigments, had better 

 be obtained from the artists' colourmen, and although they have 

 for sale almost colourless oils, such as the nut- and poppy-oils, 

 yet there is nothing better for the finer work described in these 

 pages than rectified linseed - oil and turpentine of the best 

 quality, mastic varnish, and the medium previously mentioned. 

 For ordinary work, however, the ordinary linseed- and boiled 

 oils, turpentine, and "paper varnish" — an inferior kind of 

 mastic, — with still commoner varnishes for the roughest " rock- 

 work," will be the only qualities necessary.
