Koleksi: USG

Gypsum is the foundational bedrock of USG and this wonder mineral, known as “hydrous calcium sulfate” (CaSO4·2H2O) has been crushed, and air heated, or “calcined,” which drives off three-fourths of the water as steam, in the earliest reaches of recorded history to create a “hemi-hydrate of calcium sulfate,” but more commonly called Plaster of Paris, or stucco.

Archaeologists have discovered that gypsum plaster was used by the early Egyptians for urns, vases, and the construction of royal tombs. Grecian temples were filled with plaster ornamentation, as were ancient German and French monasteries and cathedrals; in fact, Plaster of Paris got its name from the vast gypsum deposits in the Paris Basin of France. 

It’s undeniable that plaster had a rich history of use in construction due to its ability to create fire-resistant structures by the time USG opened its doors in February 1902. Simply put, without plaster, there would be no drywall—or USG.
