Marshall And All; I know that Marshall has said several times on this list that the pH of CS should be about 7.
However in the many lots that I have checked for otherss and just after reading his post I went through part of my inventory measuring pH with pHydrion Papers with a range of 4.5 to 7.5, and measured 12 more samples and everyone checks at 5.5. I have never seen anyting in CS that is higher or lower. I know Bruce Marx said 7 but I never have seen it. I guess "Ole Bob" just cna't get it right. But then I didn't manufacture the papers. :Ole Bob" Marshall Dudley wrote: > Those who are having problems with their CS changing color upon storage please > check the ph.
