crystals. We utilized low albite from Amelia Courthouse, jadeite from New Idria, California (Coleman, 1961), and high-purity Brazilian quartz (Manning, 1994). Electron microprobe analyses on 8 albite and 11 jadeite grains indi-cate the purity of both albite (<0.2 wt% CaO, <0.7 wt% K 2O, and <0.03 wt% FeO, MgO, TiO 2, Cr 2O 3, MnO) and

high-temperature, single-crystal X-ray diffraction work by Winter et al. (1979) seems to demonstrate that heating Amelia albite to about 1070"C for 100 d should produce the high degree ofAl-Si disorder required for the transformation to monalbite. (However, inversion to monalbite was not quite attained in a single-crystal

Albite Information - From Ordinary Feldspar to Collectable Gemstone. Albite is a feldspar mineral with various industrial applications. It plays a crucial role in soil nutrition by breaking down through erosion and releasing vital minerals and nutrients for thriving plants. Surprisingly, albite even finds its way into toothpaste formulations.

High purity graphite crucibles are made of 99% pure carbon while clay-graphite cruicbles have a mixture of 30-50% clay and 50-70% carbon powder. This makes high purity much more heat resistant than its clay-graphite counterpart, making it ideal for applications where extreme temperatures must be reached or maintained.
