|Scale of Hardness Collection.
The traditional Moh's Scale with a small Diamond included.
Ten Specimens 1" (except diamond), from talc #1 to diamond #10, number coded, compartmented container.
|Scale of Hardness Collection.
The traditional Moh's Scale withoutl Diamond.
Nine Specimens 1", in compartmented container.
|Tenacity Collection. Various
terms such as brittleness, elasticity, flexibility, mallability and sectility
are used to describe the particular properties of some minerals. This group of minerals displays a variety
of these properties. Six specimens 1½", number-coded, compartmented container.
|Cleavage Collection. Cleavage
is a readily recognizable property of some minerals and follows the internal crystal
structure of that mineral. Terms used in a study of crystallography apply to the cleavage
planes. Six Specimens 1½", number-coded, compartmented container.
|Luster Collection. Recognition
of the kind and degree of luster of some minerals is an aid to identification. This
collection provides examples of both metallic and non-metallic types of luster.
Fifteen Specimens, approximately 1½", number-coded, compartmented container.
|Streak Collection. Some
minerals will demonstrate a colored streak on unglazed tile which gives a key to
identification of that mineral. Some examples of this property can be demonstrated with
Eight Specimens, approximately 1", number-coded, a streak plate, compartmented container.
Some minerals (and rocks) do not demonstrate a parting or cleavage along
specific planes, but they do have a consistency in how they break. The resulting surfaces
are described as conchodial (obsidion), uneve (hornblende), etc. The important types of
fracture are demonstrateed with this collection. Six Soecimens, approximately 1½",
number-coded, compartmented container.
|Earth Science Collection.
Set of 75 rocks & minerals designed to demonstrate the major
rock-forming minerals in the scale of hardness, minersala show recognized physical
properties, i.e. streak, luster, cleavage and fracture and specific gravity. Includes
sections for study of ores of metals and non-metals, igneous, sedmentary and metamorphic
rocks. Approximately 1¼ x ¾, number-coded, includes a streak plate, magnet, magnifier,
compartmented container and study guide.
|Classroom Collection of Rocks
& Minerals. This collection is designed for general classroom
use. It provides materials for basic study in mineralogy with specific study units
essential to understanding general geology with these study groups: rock-forming minerals,
igneous, sedimentary and metamorphic rocks, ores of common metals, gemstones and minerals
in the scale of hardness.
50 Specimens, 1" approximately, number-coded, compartmented container, study guide.
|United States Rocks &
Minerals Collection. An excellent reference collection and a
valuable aid in identifying and comparing common and more rare rocks and minerals. Set
of rock-forming minerals, igneous, sedimentary and metamorphic rocks, ores of common metals, gem type minerals and minerals in the scale of hardness. 100 Specimens, approximately 5/8" mounted with name,
includes study guide. #9977
|Washington Collection. This standard collection for classroom use has been updated to match advances in present text book materials. Study units are present under these headings: rock-forming minerals, ore-forming minerals, industrial minerals and igneous, sedimentary and metamorphic rocks, 40 Specimens, approximately 2" x 1½", number-coded, compartmented container, study guide. #3392||$44.10|
|Natural Crystal Collection. Pure minerals under the proper conditions will develop into a crystal form characteristic of that mineral. Only a small percentage of minerals found in nature will clearly demonstrate a recognizable crystal form. The crystals in this collection: 15 Specimens, approximately 1½", number-coded, compartmented container. #3430||$56.75|
|Fluorescent Minerals Collection. (Short & Long Wave). This expanded collection allows a study in detail of the response of these minerals to the range of ultraviolet rays. 15 Specimens, approximately 1½", number-coded, compartmented container. #2792||$28.40|
|Fossil Collection. Examples of vertebrate and invertebrate fossils from the Paleozoic, Mesazoic and Cenazoic eras are included. 15 Specimens, sizes vary, each identified and labeled. #3313||$20.40|
