Colour of Brass
It should be remembered that while a brass that is rich in copper is of a deep golden red colour, the redness does not decrease and merge into a yellow, and the yellow become lighter, in a regular way, as the proportion of copper decreases and that of the zinc increases. It is important that this be noted as anyone ignorant of the fact would unfailingly suppose that the richest coloured brass contained the most copper.| Colour | Zinc % | Copper % |
