A fine collection of assay crucibles collected from around Nevada, and a few from Montana and Arizona. The collector was careful to put a note in many of the crucibles where they were found. These places include Tonopah, Rye Patch, Pactolus, Phonolite, Bruner, Columbus, Bovard, and a number of other classic Nevada mining camps. The collection consists of approximately 46 crucibles. 39 crucibles are classic bone ash crucibles made by several different crucible manufactures with several different shapes and sizes. These crucibles were generally used for 1/4 to 1 assay ton samples. Additionally there are seven larger crucibles, 4.5 to 6 inches in diameter, that were used for larger samples, such as 5 to 10 assay ton samples, or even some of the larger crucibles used for small bullion pours. This is a really neat group. Nevada
