The deal seems to be that the iron's kept in solution by low pH - high carbonate content, and perhaps pressure - and precipitates as the carbon <br />dioxide gasses off. They mention getting advice from European spas (they don't say what) on how to warm up the water without the rust immediately precipitating. I don't doubt the baths rapidly acquired a stain.Ray Girvanhttps://www.blogger.com/profile/05556764642402680159noreply@blogger.comtag:blogger.com,1999:blog-8937414969460147900.post-21848184069250605522014-04-28T09:10:28.699-07:002014-04-28T09:10:28.699-07:00Ray, your posts always lead me to interesting thin...Ray, your posts always lead me to interesting thing. In this case it is the ferruginous baths (chalybeate). What exactly this entails is a mystery. It certainly must refer to some sort of iron in the water but if it is alkaline at all, iron precipitates as iron oxide. The stability constant for this is very high so there is very little free iron left in the water. So, I would really be interested in what the chemical composition of the bath water was. It must be particulate iron oxide (rust) since you show pictures of it. Imagine, bathing in rust. It might be akin to a tanning booth. <br />Searching this out also led me to "electric baths." Seems like a contradiction in terms and does not mean throwing a hair curler into the water. In fact, Kellog, of cereal fame, recommended incandescent lamps for just about everything that ails you:<br />http://lifestylelaboratory.com/articles/kellogg-protocols.html<br />Actually, there are a number of uses for light including phototherapy for newborns and light activated drug delivery.
