Barium Sulphate is also known as Barite and Blanc Fixe.
It is a dense mineral used in many applications as well as paint. It is found throughout the world and in it's mineral/crystal form it can be very beautiful, it is pictured opposite. This particular pigment is reclaimed from industry and after careful washing, sieving and drying is recycled into this paint.
In masstone it is an almost white, warmish grey colour. It is unusual in it's handling with an putty like feel but still brushes out like oil paint. It is transparent and for those wanting to preserve transparency in tints, it will be very useful.
Honestly this paint is unusual, however when combined with some of the weaker tinting paints which are too dominated by using Titanium white it would be really useful.
You could obtain a wider range of tints from something like a green earth with this and it is much easier to control than Titanium white.
Harmonius with the rest of this range of sustainable colours.
