"Ward's® Thermochemistry In The Bag Inquiry Demonstration Activities"

Feldspar group; greenish gray alkali feldspar, coarse crystalline, some iridescence.

The CENCO Ballistic Pendulum is the industry standard for the investigation of momentum and energy.

When minerals, rocks, and fossils cannot be accurately identified by macroscopic observation and testing, thin section slides can reveal the composition and structure of the specimens on a microscopic level.

Massive, chlorite-rich.

Light gray, fine-grained, well-foliated, schistose.

Gray-to-brown basaltic, with over 50% vesicles.

Red-brown to gray, coarse-grained, containing feldspar and mica.

Brazil.

Gray and poorly sorted, with a gritty texture.

Good grade, brass-yellow copper ore, massive.

Dark, coarse-grained, and composed chiefly of hornblende.

Brown, earthy, massive; used for yellow pigment.

Our excellent series of standard thin sections features important and interesting rock-forming mineral types most often found in field samples.
