In Karlovy Vary, Czech Republic, there is a “petrifying facility” underneath one of the streets. We have visited the location and described it via photographs and text in our newest book, Untold Secrets of Planet Earth: Catastrophic Caves. At this location, the thermal mineral water is directed to flow over hand-made paper roses. After fourteen days, they gain a coat of aragonite (a form of calcium carbonate). The water is high in carbonates and other residual minerals. The red-orange colouring of the objects is due to the high iron content of the water. The red-orange colouration is deposited during the drying phase. The iron in the water reacts with the oxygen in the air to form a hematite-limonite layer on the outside. They are neither permineralized nor petrified if one wants to get technical. Most people, without a geology background, however, would just call them “petrified". They show "rock" does not take a long time to form; "rock" only takes the right chemical and physical conditions to form.
