Rock and Mineral Specimens and Collections
Eisco™ Sphalerite Mineral Specimen
Sphalerite is a sulfide often mined for its zinc content and is typically associated with other sulfide minerals such as pyrite and chalcopyrite.
Eisco™ Phenylthiourea (PTC) Paper Test Strips
Genetic Taste Testing Phenylthiourea (PTC) Paper Strips are used to demonstrate the effects of heredity on taste
Eisco™ Raw Fluorite, Mineral Specimen - Hand Sample - Approx. 3 Inch
Fluorite Mineral Specimen is used in classroom identification lab exercises and for study of uncommon 4-plane cleavage pattern.
Eisco™ Oolitic Limestone Sedimentary Rock Specimen
Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids, tiny nodules formed from the accumulation of carbonate material around a nucleus. Oolitic limestone forms in reef or lagoon environments.
Eisco™ Phyllite Specimen
Phyllite Specimen for demonstrations of metamorphic properties, such as glossy sheen and dense, foliated minerals.
Eisco™ Argillaceous Shale Specimen
Argillaceous Shale Specimen is formed from cementation and lithification of very small grains of rock, commonly mud or clay.
Eisco™ Oolitic Limestone Specimen (Sedimentary Rock)
Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids.
Eisco™ Arkose Sandstone Specimen (Sedimentary Rock)
Arkose Sandstone is clastic sedimentary rock made up of angular, poorly-sorted sand-size grains.
Eisco™ Chalcopyrite Mineral Specimen
From the same family as fool's gold, Chalcopyrite is a yellow crystalline mineral consisting of a sulfide of copper and iron. It's the principal ore of copper formed in hydrothermal veins.
Eisco™ Milky Quartz Mineral Specimen
Milky Quartz Mineral Specimen has a tightly packed framework and hardness of 7, complete lack of cleavage planes, and distinct euhedral crystal habit.
Eisco™ Mica Schist Specimen
Mica Schist Specimen for use in lessons on metamorphic rock properties, classification, and identification.
Eisco™ Pegmatite Igneous Rock Specimen
Pegmatite is an igneous rock that contains two vastly different crystal sizes. This combination of both phaneritic and aphanitic crystals indicates this rock formed at two vastly different cooling rates.
Eisco™ Coquina Sedimentary Rock Specimen
Composed of bone and shell fragments, coquina is nearly 100% fossil matter. Held together by a carbonate cement, this skeletal mass forms in low-energy environments such as lagoons and reefs.
Eisco™ Graphite (Pure Carbon) Specimen
Graphite specimen correlates well to Next Generation Science Standards Evidence Statements.
Eisco™ Lodestone Mineral Specimen
A naturally magnetized mineral that creates its own magnetic field and can pick up small metal objects.
