About Alabaster
Formula:
CaSO4 · 2H2O
Name:
The name is derived from its supposed early source at Alabaston in Egypt.
A fine-grained massive form of gypsum.
Note that archaeologists and the stone processing industry use the word differently from geoscientists. The former use it in a wider sense that includes varieties of two different minerals: the fine-grained massive type of gypsum and the fine-grained banded type of calcite ("calcite-alabaster", "Egyptian alabaster", "Oriental alabaster", "onyx-marble").
