The Galaxy 4, 1873
Uncrystallized or amorphous silica has been found by M. Kerinam to possess important properties as a mordant, especially for aniline colors. On agitating precipitated and washed silica with a solution of fucsein, aniline blue, or aniline violet, the silica takes a strong color, and thus powders may be formed which are susceptible of many applications in the arts.
