Rock and Mineral Specimens and Collections
Eisco™ Mohs Hardness Kit
This Tech Cut Mohs Hardness Kit includes 8 specimens with streak plates.
Eisco™ Diorite Specimen
Diorite Specimen straddles the line between mafic and felsic rock chemistry.
Eisco™ Apatite Specimen
Apatite is a common phosphate mineral often found as an accessory mineral in igneous rocks or as concretions or detrital clasts in sedimentary rocks. A standard Mohs hardness of 5 and a relatively uncommon crystal habit.
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™ Garnet Mineral Specimen
Garnet forms under intense heat and pressure conditions, making it a common mineral in mountainous terranes.
Eisco™ Conglomerate Specimen
Conglomerate Specimen has large clasts that indicate that pieces of rock underwent large amount of rolling, bouncing, and other weathering to become round.
Eisco™ Chlorite Mineral Specimen
Chlorite is a metamorphic mineral that has undergone light alteration.
Eisco™ Augite (Pyroxene Mineral) Specimen
Augite (Pyroxene Mineral) Specimen suitable for use in classroom identification lab exercises and for study on 2-plane, 90° cleavage.
Eisco™ Sedimentary Rocks Kit with Storage Box and ID Card
A fun introduction to the world of geology through a 12-piece rock kit. Each Tech Cut specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features.

Eisco™ Phenylthiourea (PTC) Paper Test Strips
Genetic Taste Testing Phenylthiourea (PTC) Paper Strips are used to demonstrate the effects of heredity on taste
Eisco™ Phyllite Specimen
Phyllite Specimen for demonstrations of metamorphic properties, such as glossy sheen and dense, foliated minerals.
Eisco™ Biotite Mica Mineral Specimen
Biotite Mica Specimen suitable for use in classroom identification lab exercises and for study on 2-plane, 90° cleavage.
Eisco™ Gypsum Mineral Specimen
Gypsum Mineral Specimen ideal for use in study of cleavage and fracture as example of imperfect cleavage planes.
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.
