Quartzite is hard, non-foliated rock formed from metamorphosed quartz sandstones.

Hornblende is a dark amphibole group mineral, perfect for teaching Bowen's reaction series.

Massive white quartz with a moh's hardness 7.

Introduce your students to Gray Andesite with large phenocrysts of hornblende.

Limestone is a gray calcium carbonate that will fizz with dilute HCl.

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.

Coarse, 'salt and pepper': dark pyroxene and light andesine. Provides perfect representation of an intermediate igneous rock.

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.

Slaty metamorphic rock containing hematite giving it its red color.

The Variable Speed Wave Generator is a new concept for generating waves in your stream table. The paddle enters the water, forms the wave, then is withdrawn to eliminate back waves.

Ideal for sampling ponds and lakes.

Bituminous rich black shale for hands-on investigations.

Talc is the softest know mineral with a moh's hardness of 1, and composed of clay.
