Received Rosa Gallery watercolors in this condition
Bought these a week ago as they were on sale as they're expired (on paper) (mfg: 2019, expiry: 2024). I did a little research to see if paints actually expire and they don't.
Most of the shades survived (I think) except Cobalt Turquoise, Burnt Sienna & Umber (maybe)
Cobalt Turquoise looks too transparent & Burnt Sienna is grainy
I've made an amateur swatch card (slide 2).
I've added a few drops of water to all of them and mixed them a little on the top as the binder had separated.
Is there a way to save these 2 shades? Is burnt sienna specifically prone to this type of graininess?
