A hot (58.7 °C) sulfate-chloride spring led by sodium and calcium, neutral in pH and moderately mineralized at 1,218 mg/kg — the kind of water with real body to it. Metasilicic acid runs high at 148.7 mg/kg, leaving the thin silica film that makes skin feel noticeably smoother afterwards. Almost colorless and clear at the bath inlet, with a metallic iron edge and a faint salty note on the lips.
