Bismuth subnitrate (BiONO₃)
Bismuth subnitrate is a chemical compound used in ceramics to create opaque, pale yellow and soft white glazes. Bismuth, the main heavy metal in this compound, is noted for being non-toxic, making it a safer alternative to other heavy metal compounds, such as lead. Thanks to its non-toxic properties, bismuth subnitrate has gained popularity as a component in ceramic glazes for tableware and other household products, allowing the creation of pieces without the risks associated with the use of lead.
In addition, bismuth subnitrate is increasingly used in contemporary ceramics due to its opacifying properties and its ability to generate finishes with a smooth and elegant texture. This makes it ideal not only in the production of tableware and household utensils, but also in artistic pieces and luxury ceramics, where the aesthetics of the finishes and the safety of the final product are essential aspects.Interesting Fact
In addition to its use in ceramics, it is also used in cosmetics and pharmaceuticals. In these sectors, bismuth subnitrate has been used in the formulation of skin creams and ointments due to its astringent and soothing properties.Helpful Tip
If you are looking for a safe and effective option for creating opaque glazes, consider using bismuth subnitrate. It is particularly useful if you want to achieve soft, satiny colors without having to resort to more toxic materials.
