Use of brushes for lustre work:
is very easy to contaminate your lustres (and most of us have done
it). Consequently, it is ideal to have a brush for each lustre
colour. Economically this is not always possible or desirable. I
recommend a brush for each family — i.e. a brush for the yellows/browns,
a brush for blues, a brush for pinks etc.
Each brush should be labelled.
I clean my lustre brushes thoroughly
after use—even if it is a brush kept for a particular colour or family
of colours. After use, wash out in Pure Gum Turps or Odourless Brush
Cleaner. I keep a small jar specifically for cleaning lustre brushes and
I replace the solvent in this jar regularly. I wash the brush 4 or 5
times in the solvent and then once or twice in Methylated Spirits. By
cleaning so thoroughly, there is little risk of contaminating your
lustres next time around.
