The phenomenon that liquid in connected tubes stays always at the same level is called today the „system of communicating tubes“. By knowing this and understanding at the same time the capillary effect we have the possibility to let our water colour brushes display all their beautiful capabilities.
The
-COSMOTOP-MIX series, our mixed natural hair/synthetic brushes, have benefited by all this knowledge. The full natural hair body within the brush-head has the effect of a liquid reservoir, supplying the brush-tip, consisting of a small amount of synthetic fibres, continually with paint.
