Despite the relative high abundance of barium sulfate in nature - it's the 14 most abundant element in earths crust - due to its multiple uses it has a high value, in the range of $55/100grams. Total annual world production is estimated at around 6,000,000 tons. And the main mining areas are the UK, Italy, the Czech Republic, USA and Germany.

Barium sulfate is used to identify the teeth from the diagnostic wax-up in a 20% BaSO4 solution. If a soft tissue (flapless surgery) template is to be made, teeth are ideally identified with a 20% BaSO 4 solution, and the base (soft tissue) uses a 10% mix. This allows for differentiation of the teeth from the soft tissue.
