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.
AquaPhoenix Scientific Milky Quartz
This naturally opaque milky quartz sample is ideal for geology lessons, rock collections, and hands-on earth science education. Sized 1 to 1.25 in., each specimen showcases the common form of crystalline silicon dioxide.
Eisco™ Phenylthiourea (PTC) Paper Test Strips
Genetic Taste Testing Phenylthiourea (PTC) Paper Strips are used to demonstrate the effects of heredity on taste
Eisco™ Olivine Mineral Specimen
Olivine Mineral Specimen for teaching students about mineral physical properties like hardness, fracture, and luster.
Eisco™ Halite Mineral Specimen
Halite Mineral Specimen ideal for teaching students about cleavage planes and how evaporate deposits form.
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™ Magnetite Mineral Specimen
Magnetite grains align themselves with the earth's magnetic field, preserving a record of the field's direction when forming igneous rocks.
Eisco™ Garnet Mineral Specimen
Garnet forms under intense heat and pressure conditions, making it a common mineral in mountainous terranes.
Eisco™ Lodestone Mineral Specimen
A naturally magnetized mineral that creates its own magnetic field and can pick up small metal objects.
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™ Granite Specimen
Granite Specimen is a must-have sample when discussing rock types, rock cycle, formation, classification, and identification of igneous rocks.
Eisco™ Chert Mineral Specimen
Sometimes referred to as flint, Chert is a sedimentary rock rich in silica.
Eisco™ Gypsum Rock Specimen, 3cm
Gypsum is a sulfate mineral formed as the byproduct of evaporating saltwater. When this mineral becomes lithified, it forms rock gypsum, a sedimentary rock. These 3cm samples are great for use as classroom specimens or as a part of a small rock collection.
Eisco™ Dolostone Sedimentary Rock Specimen
Dolostone is a lithified form of dolomite. Composed primarily of carbonate material, dolostone is a more stalwart rock than its chemical cousin, limestone. It is often mined for construction and infrastructure purposes.
Eisco™ Hematite Mineral Specimen
Hematite Mineral Specimen is made up of iron and oxygen, giving it distinct red, earthy color.
