Watercolour, humour, this and that

Friday, 29 November 2013


Thought it would be interesting to see how the two react with bleach.  I had only ever used bleach on Brusho and it was suggested that you could use bleach on Watercolour too.  So Polly had to experiment and here are the results, which you might find interesting.

This is the Brusho chart. Using all the colours that I have.  With the exception of Prussian Blue on all the above I used just one sweep of a brush loaded with bleach (or you can use Milton (a sterilising agent)   And the whiteness of the paper just appeared through as if by magic.   Obviously some reacted better than others.  The paper didn't turn yellow and wasn't damaged.  In fact, I have tried and you can paint over the top when it is dry.  Could be very handy to know. 

Watercolours and exactly the same procedure BUT I had to scrub the bleach into the paint, no single strokes here, so was worried about the paper and the brush (an old brush that I washed constantly) And while I can see that some of the colours allowed the white paper to show through, many of them, even after the vigourous brushing, did not turn white.  The scrubbing affected the wash giving run backs sometimes.  I wouldn't use bleach on a watercolour painting from choice, as I feel it could damage the washes around the bleached area, not to mention quickly ruin any brush.

I would be interested to hear from anyone else who has tried a similar experiment.

Have a wonderful weekend my lovely blogging friends!!
