Rock and Mineral Specimens and Collections
Eisco™ Halite Mineral Specimen
Halite Mineral Specimen ideal for teaching students about cleavage planes and how evaporate deposits form.
Eisco™ Corundum Mineral Specimen
For study of mineral hardness and crystal habit - EISCO Corundum Mineral Specimen is used in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements.
Eisco™ Arkose Sandstone Specimen (Sedimentary Rock)
Arkose Sandstone is clastic sedimentary rock made up of angular, poorly-sorted sand-size grains.
Eisco™ White Quartzite, Metamorphic Rock Specimen - Hand Sample - Approx. 3 Inch
Quartzite is formed from sandstone that has been tightly compressed to the point where the clasts have recrystallized to form a new rock. This formation mechanism, coupled the inherent strength of quartz, makes quartzite a very durable rock.
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™ Phenylthiourea (PTC) Paper Test Strips
Genetic Taste Testing Phenylthiourea (PTC) Paper Strips are used to demonstrate the effects of heredity on taste
Eisco™ Apatite Mineral Specimen
Apatite Mineral Specimen ideal for use in lessons about the Mohs hardness scale.
Eisco™ Muscovite Mica Mineral Specimen
Muscovite Mica Mineral Specimen forms in thin sheets that are individually weak, but comprehensively strong.
Eisco™ Microcline Feldspar Mineral Specimen
Microcline Feldspar Mineral Specimen for use in study of physical properties like hardness, cleavage, and crystallization temperature.
Eisco™ Hematite Mineral Specimen
Hematite Mineral Specimen is made up of iron and oxygen, giving it distinct red, earthy color.
Eisco™ Gypsum Mineral Specimen
Gypsum Mineral Specimen ideal for use in study of cleavage and fracture as example of imperfect cleavage planes.
Eisco™ Quartz Mineral Specimen
Quartz mineral specimen for use in classroom identification labs and exercises.
Eisco™ Dolomite Mineral Specimen
Dolomite is similar to calcite but includes magnesium in its chemistry, which makes it a more robust and stable mineral.
Eisco™ Sandstone Specimen
Sandstone Specimen is made up of well-sorted and well-rounded grains of quartz.
Eisco™ Granite Specimen
Granite Specimen is a must-have sample when discussing rock types, rock cycle, formation, classification, and identification of igneous rocks.
