Handmade watercolours made – now the fun of using them begins.
Until I’ve tested the paints for consistency and lightfastness, I’m not using them in any painting that’s for sale. I have to be able to guarantee the quality of my materials and while the handmade watercolours are really interesting, they’re not yet tried and tested.
In the meantime, I’m getting to know them by painting a series of greeting cards which are being sent off to family and friends.
Testing handmade watercolours
Here’s my testing process so far:
Naturally, I’m creating swatches in my colour journal. The details will be added as I get confirmation of the characteristics of each paint.
I also wanted to see how the paint reacted in different papers. As I mixed them, I tried each one on three sheets of watercolour papers of various weights and textures. They reacted well on all of them. Now I’m checking specifically for colour fastness – which will take time.
To do that, I’ve painted a stripe of each of my 13 handmade watercolours on two different papers. One is a 300lb watercolour paper, and the other a mixed media paper.
Each sheet has now been sliced down the middle. Half of each sheet has been placed in a brown envelope and placed between large books on my bookshelf to block out as much light as possible. The other half of each sheet has been placed on a south facing windowsill where it is exposed to moderate sunshine. Next January, I’ll compare the sheet halves and see how well the sunlight exposed paint has fared.
