I have tested this new water colour brush series 152. It is made of synthetic Kolinsky red sable hair. I have extensively tested this brush and would like to give you my feedback and recommendation:
The brush can perfectly be used for all common water colour painting techniques. The hair is an almost perfect immitation of the delicate natural hair. The hair does not break, it does not spread and it bounces back. This brush also holds the tip permanently very well and and there is no troublesome dripping, as it often happens with normal synthetic hair. The brush should always be well wet and should therefore be able to hold plenty of water. Because of its characteristics it is less suitable for dry acrylic paints and other dry painting techniques.
It is excellent for slow, delicate painting, for the dry-brush technique, wet into wet technique, flat wash, gradated wash and other wahing techniques.
Altogether I can really recommend this brush. Another new high quality product from lineo, handmade and individually tested in Germany.
