A porcelain combustion boat is a laboratory tool used for the combustion of organic substances. It is a small, boat-shaped container made of porcelain, a type of ceramic material that is able to withstand high temperatures and chemical corrosion.

Porcelain is a common material for combustion boats due to its high resistance to chemical corrosion and its ability to withstand high temperatures. The combustion boat is used to hold a sample of an organic substance, which is then burned to determine its elemental composition.

Combustion boats are commonly used in analytical chemistry and other laboratory applications where the analysis of organic substances is required. They provide a cost-effective and convenient solution for combustion in laboratory settings.
