Rock and Mineral Specimens and Collections
Eisco™ Granite Specimen
Granite Specimen is a must-have sample when discussing rock types, rock cycle, formation, classification, and identification of igneous rocks.
Eisco™ Basalt Specimen
Basalt is formed quickly from an iron-rich magma and exhibits a dark color and small crystal size.
Eisco™ Bituminous Coal Specimen
Bituminous Coal is formed in anoxic environments from compressed organic matter, and is used worldwide as a fuel source.
Eisco™ Streak Plates for Minerals
The off-black, unglazed porcelain of these streak plates show a mineral's color in powder form, or to identify the mineral content of a rock.
Eisco™ Carbonaceous Shale Specimen
Carbonaceous Shale Specimen is formed from cementation and lithification of very small grains of rock, commonly mud or clay.
Eisco™ Pumice Specimen
Pumice is formed quickly during volcanic eruptions around pockets of air within lava.
Eisco™ Mineral ID Kit
Test mineral hardness, streak color, magnetic properties, appearance, and effervescence to identify different minerals and mineral content within rock specimens. The Mineral ID Kit is a fun way to explore the variety of techniques that geologists use to identify rocks and minerals.
Eisco™ Hematite Mineral Specimen
Hematite Mineral Specimen is made up of iron and oxygen, giving it distinct red, earthy color.
Eisco™ Mica Schist Specimen
Mica Schist Specimen for use in lessons on metamorphic rock properties, classification, and identification.
Eisco™ Microcline Feldspar Mineral Specimen
Microcline Feldspar Mineral Specimen for use in study of physical properties like hardness, cleavage, and crystallization temperature.
Eisco™ Slate Specimen
Slate Specimen for use in metamorphic classification and identification exercises.
Eisco™ Gabbro Specimen
Gabbro forms when iron-rich magma too heavy to reach surface cools slowly over time.
Eisco™ Anthracite Coal Specimen
Anthracite Coal is formed in anoxic environments from compressed organic matter, and is used worldwide as fuel source.
Eisco™ Chert Mineral Specimen
Sometimes referred to as flint, Chert is a sedimentary rock rich in silica.
Eisco™ Fossiliferous Limestone Specimen
Fossiliferous Limestone Specimen for sedimentary rock identification and studying fossils within whole rocks.
