A porcelain basin generally refers to either a laboratory evaporating dish used for heating and concentrating chemical solutions, or a bathroom/kitchen sink made from high-fired, glazed ceramic. Both are prized for their extreme durability, heat resistance, and non-porous, glossy finish.

Laboratory Porcelain Basins
Used in scientific and research facilities, these small, round-bottomed dishes are designed for boiling, evaporating liquids, and isolating chemical solutes
Material Composition: Crafted from laboratory-grade porcelain that is chemically inert to avoid reacting with strong acids or alkalis.Design Features: They usually feature a shallow or deep round form with an integrated spout for easy, controlled pouring.Thermal Properties: Capable of withstanding extreme temperatures (often up to ~ 1000°C), they are highly resistant to thermal shock and are safe to use with Bunsen burners.Sizes: Available in a wide variety of volume capacities, ranging from tiny 10 ml dishes to 6000 ml for larger-scale experiments.
