Thank you, Chris, for this valuable information. This had been a recent
change from my routine of keeping the silver in colbalt blue glass bottoes
that only hold 4 oz, as opposed to the 16 oz plastic brown peroxide bottle.
Someone also suggested the presence of peroxide could cause the color change.
But potency would be a concern if the plastic reduce that.
Sincerely,
Nancy Berntsen
