One large factory in Elberfeld lately sold to a public company showed net profits for the year 1872 amounting to about £60,000, of which about £50,000 are said to consist in profits made in the production of Alizarine.
Notwithstanding this, the manufacture of Alizarine from Antra-cene may be considered to be in its infancy yet, and hitherto the only practical use, on a large scale, made of the Alizarine bas been for printing varions shades of violet, brown, and red.
In these colours, however, already the superiority of the artificial Alizarine over the natural bas been proved to great advantage, for while in employing natural Alizarine the material to be printed must almost invariably be mordanted first and then printed, the printing with artificial Alizarine is effected in one operation, as the mordant is mixed with the colour. This, of course, is a decided advantage.
As soon as the application of artificial Alizarine for dyeing Turkey red, which lias hitherto been successfully accomplished by a few manfacturers only, lias become general, the artificial Alizarine will attain its real position, and then it is more than probable that the Antracene produced from coal-tar will be utterly insuffi-cient to meet the demand for the article,
A patent of Fenner Versmann, for the production of Antracene from coal-tar pitch, is beginningtobeworkedhere.and in America, but it is hardly likely that, even in case of success, the additional quantity of Antracene obtained by the application of this patent process will be sufficient to meet the demand for this article.
Varions plans have been suggested by seientific men for the production of Antracene from other substances, but hitherto none have been successfully worked ; at least, the Antracene so obtained costs more to manufacture than the Antracene from coal-tar.
We estimate that the production of Antracene in the year 1872 repiesented a value of about £200,000 sterling, all of which three years ago was running into the gutter, and that in the eurrent year the production of Antracene will be far larger still than in the previous year, as many manufacturers who were reluctant to manufacture Antracene in the beginning, bave now been induced to alter their minds, seeing the great profits realized by those who have begun the manufacture last year, or before ; nevertheless, as already stated, there is every prospect of the supply falling short of the demand.
