Talk:Methods Manual for Salt Lake Studies/Hardness

I am moving the section on Rockwell Hardness testing, donated by Fuland123, from this page on testing brine hardness, and placing it into a separate page on measiuring the hardness of salt/gypsum/calcite/clay crusts on dry playa lakes. This page describes the method for measuring water 'hardness', which really means the sudsing ability of a brine or water and is actually a measure of the Mg and Ca content of the brine. It has nothing to do with the physical solidity (is that the word) of the brine.Peri Coleman (talk) 07:13, 18 January 2009 (UTC)
