Total newbie here
I've recently taken to making my own watercolour paints because apparently I hate my shoulder muscles and my carpets.
I've got most of the process down but I cannot figure out for the life of me when to stop mulling.
Is there a clear indication for when the pigment is fully dispersed?
I've been told to look out for when it goes shiny but that happens pretty fast and testing the paint doesn't shed much light for me either.
An example is I spent most of this afternoon making a Prussian Blue (using Prussian Blue LUX 45202 from Kremer) - I recorded myself doing it to try and see a difference in start and finish (and redefine watching paint dry) and from about 5 minutes in, it looks the same. I mulled away for over an hour and can't help but think I could have got away with just those first few minutes.
I know that each pigment will have a different mix time, and a different binder ratio, but how do you know when you've got it right?
