Deluxe Hardness Pick Set with streak plate and magnet
The Deluxe Hardness Pick Set is a tool for Mineral Identification, including a set of Hardness Points for performing a 'scratch test' on an unknown mineral to determine its Hardness under the Mohs scale. This deluxe kit includes two other mineral identification tests - a Streak Plate for determining an unknown mineral's inherent Color, and a Magnet for testing for minerals such as Magnetite, Pyrrhotite, and Nickel-Iron Meteorites. All of this comes packaged in a beautiful mahogany-finished Wooden Case.
This set includes 8 Mohs' Hardness Points from Mohs' 2 through Mohs' 9, nicely mounted in nickel-plated Brass, color-coded, number-stamped, and double-ended Pin Vises, along with two Hardness Plates of Mohs' 3.5 and 5.5, a Streak Plate, a Magnet, and a 100x Sharpening Stone, enhanced by Instructions, Table of Minerals sorted by Mohs' Hardness, all neatly packaged in a compact, Wooden Case.
To perform a scratch test, select a numbered Hardness point, and try to scratch a flat, smooth surface of the mineral. For example, if the number 6 point scratches your mineral, but the number 5 point does not, then your mineral has a Mohs' Hardness value of about 5.5. This is an important mineral identifying criteria.
The Hardness Points are made of Metals and Alloys of equivalent Mohs' Hardness as the mineral standards, so the points will not break off, and they can easily be re-sharpened, and ultimately replaced after many years.
