The '''borates''' are [[compounds]] of one or more [[metallic]] [[elements]] with the [[borate]] radical. There are two types of borates: the first, primary type is [[anhydrous]] (without [[water]]), and develops in [[igneous]] and [[metamorphic]] [[environments]], where it is both [[rare]] and [[stable]]; the second type, the [[hydrous]] borates, develop in [[sedimentary]] [[rock|rocks]] at the bottom of [[playas]] in [[arid]] regions. Many of the hydrous borates are readily [[soluble]] in water, and the dryness of their environment aids greatly in their preservation. The hydrous borates are  [[brittle]] and relatively soft, and are  [[white]], [[colorless]], or [[transparent]]. The anhydrous borates are dark in color and heavy.
