Thanks for this forum. I just finished a five pound box of magnetic clay recently. My last bath I used probably 5-6 cups of the clay and was in the bath for just over 20 minutes. There was so much more black gritty stuff in the bath when the water drained out than I have ever experienced with previous baths just using 2 cups of clay. I was fighting a winter cold type of thing and this was one of my modalities. I had my Amalgams replaced last December, but the dentist did not use dams or other precautions. I have done 10 or 11 Liver Flushes since then - losing count. I have had all the vaccinations growing up - my mother was a nurse (she did not start to lose faith in the medical community until the consequences of in utero DES twenty years earlier became apparent in my older sister with uterine cancer/infertility, etc.) I used the general detox formula from magneticclay.com. I have not been tested for heavy metals, so I do not know exactly which ones I am high in, but probably mercury, aluminum, cadmium (ex-smoker) and others.
