Burnt Sienna, a rich brown pigment obtained by burning Raw Sienna, is a classic choice for professional watercolour artists. Its origins trace back to Siena, Italy, where it was commonly sourced during the Renaissance period.

This transparent pigment exhibits warm red-brown hues that add depth and character to artworks.

Notable components include MBIT and IPBC, a biocidal product.

It's important to note that Burnt Sienna may trigger allergic reactions and skin sensitisation in some individuals.
