Hi Everyone! Thanks for taking the time to read this.
So I have a couple of queries:
1. A couple of pigments I've been making, I mull and add binder in small amounts (measuring) until it doesn't rub off, but also dried without being sticky when I put a small bit on my palette. HOWEVER, then when I put it into pans to dry, it cracks a lot. The cake isn't uber dry or anything, and rewets easily, but there are large chasms in my half pans now xD
I've read somewhere this could be due to too much binder, but any less and the pigment doesn't seem to go into solution.
2. One set of paints I made a month ago are still tacky to the touch - much more so than anything else I've made (paint comes off on my finger when I lightly touch it), and pigments seem to have settled a little (a multi-pigment mix). Would it be worth taking the paints out of the pans and trying to keep mulling it? I don't really want to throw it away!
3. What happens if too much glycerin is added? I'm curious about that xD
Thanks again!

Did you use Glycerin in your Binder?
It should help a bit with the Cracks.
Too much Glycerin keep your colors long wet.
Too much Honey makes it sticky .
Maybe you can try to soak your older batches in the pan, pour it out and then mull it?
I have been using glycerin in my binder, but I'm wondering if the ratio is off - I've had other paints where there's been too much glycerin and it's gone dodgy (including the one below), so I've been scaling back the amount I use. For most paints it's fine, but a few of the earth colours are really playing up with me! Are there other reasons that paints crack (it's not an issue of them being really dry and brittle, they seem to just crack in the pans.
I might try remulling bits of the uber tacky mix (a separate paint that I've been making). It's really weird as I've made the paint before and it's been fine for this particular one, but this batch is weird. It must be something with the new binder I was using.
Thanks :)
From what I've read cracking comes from too much Gum Arabic or not enough glycerin, so for those particular pigments they probably just require a bit more glycerine than other pigments :)
