The gypsum slurry is then extruded between paper backing, and, after setting up, sheets are cut to specific sizes. Drying in large gas-fired ovens cures the wallboard. The final product is shipped by either truck or rail from the plant facility. Mining Gypsum was first mined in Arkansas in 1922, with continuous production starting in 1936.
