Material Composition Updates

Since we use many mined materials, their composition changes from time to time. Sometimes these are blended materials and sometime they are straight from the mine. These changes in composition can have significant effects on our glazes and clay bodies so it is best to keep on top of them as they happen. This section documents those we have become aware of since publication of Mastering Cone 6 Glazes.
