Hello all. I have a question relating to the solubility of paints when you glaze over them.

I use winsor and newton professional watercolour paints. I was finding that when I glaze over paynes grey and neatural tint on my paintings the colour would disolve into the glaze.

I therefore did the test below where I did some dry brush work of French Ultramarine, Sepia, Neutral Tint and Paynes Grey (left to right), on my usual paper which is Saunders Waterford.

I then glazed over with a wash of Permanent Rose, and this confirmed that the Neutral Tint and Paynes Grey are a lot more soluble and dissolved into the wash of Permanent Rose. The Ultramarine and Sepia kept their texture more. All 4 paints were strait out of the tube.

Has anyone else found a problem with this? Is there anyway of knowing how soluble paints are / how easily distrubed they are?

I am tempted to try the same experiment with Daler Rowney paints to see if they are any better for glazing over existing washes of paint.

Any guidance would be gratefully received. Many thanks,

Sam Leonard
