Epsom Salts Monorail Epsom Salts Monorail The Epsom Salts Monorail or Magnesium Monorail was a short-lived Lartigue Monorail in San Bernardino County, California, in the United States. It was built to carry epsomite (hydrated magnesium sulphate) from a deposit in the Owlshead Mountains to a siding of the Trona Railway. It ran nearly due east from Trona, for a distance of about .

Hydrated silica an odourless, tasteless, white, gelatinous substance, which is chemically inert. Chemical Formula: SiO · HO Diatomaceous earth, originally mined as "tooth powder" is a naturally occurring hydrated silica. As a fine gel abrasive, frequently combined with softer calcium carbonate (from chalk) it helps to remove plaque. Milled to a slightly larger size, the grains are more aggressive and are used in tooth bleaching formulations. It also has synergetic effects when compounded with traditional flame retardants such as magnesium hydroxide and aluminium hydroxide. Hydrated silica is listed by the US Food and Drug Administration as "Generally Recognized as Safe". Toothpaste: Chemistry:
