Business style hotels generally use white porcelain bowls

Are you asking whether white porcelain bowls are generally used in business-style hotels? yes.

Business-style hotels are generally made of white porcelain, while high-end hotels are generally made of bone china or magnesia jade porcelain.

White porcelain bowls are made of inorganic silicate materials. Their main chemical components are Na2O.CaO.nSiO2. Of course, some also contain small amounts of AI2O3 and P2O5.
