Foolish duchess picked up mineral

Usage examples of silicate.

She had found four species that adsorbed heavy metals, and two that absorbed dissolved silicates and fixed them into their rigid stalks.

Not the least curious part of this outcrop is the black thread of iron silicate which, broken in places, subtends it to the east: some specimens have geodes yielding brown powder, and venal cavities lined with botryoidal quartz of amethystine tinge.

Some marvel of internal chemistry allowed the animal to sprout cupric silicates from its skin.

Now he saw that where his scrabbling feet had kicked away the adhering granules and accumulated cupric silicates, something black and shiny lay underneath.

The smoke thus produced reduces the red ferric oxide to blue-green ferrous oxide, or to metallic iron, which combines with the silica present to form a fusible ferrous silicate.

Similarly, if to a silicate of lime we add oxide of iron, or soda, or even alumina, a fusible double silicate will be formed.

So, too, soda, which is a very strong base, may act prejudicially if it be in sufficient excess to set free notable quantities of lime and magnesia, which but for that excess would exist in combination as complex fusible silicates.

Noumeite and garnierite are hydrated silicates of nickel and magnesia.

Everything was UV with anxiety, and the new branch ind on the wall had to be shielded by a special silicate cup to prevent distortion.

Thariinye adjusted the assembler to produce other silicates such as tourmaline and iolite, orthoclase and microcline.

The silicate of potass was manufactured at a glass-house, by fusing equal parts of pearl-ash and sand.

Careful examination of the site disclosed silicate and magnetite dispersion matter and spherules of an intermediate type attributable to the Tunguska object.

The next half dozen headed straight for the center of the Associative, where a cylindrical conclave of walls housed the rare earths and mineral salts vital to silicate health and growth.

Brother Halga explained that the whole structure had been synthesized from glass and silicates extracted from the brecciated ice and bound together by diamond wire.

Intricately carved from deposits of hydrous silicate of magnesia, a mineral substance formed by nature from the remains of prehistoric sea creatures, these exquisite pipes were treasured by their owners, who were fond of comparing their abilities to season them.
