So, I have recently switched from e'tac to Createx Illustration paints. But look at the photo, this is illustration white that I bought in a 16oz. bottle along with black & Paynes Gray to compliment the Bloodline master set I got a few weeks ago. Because I dispise the flip cap bottle instead of twist caps I have a bunch of 1oz twist bottles that I refill, or use for custom colors on extended projects. I waited over a month to get it in from Coast who shipped it out to me the day they got it from Createx. This separation happens daily, in fact I've seen it seperate in less than an hour in my cup with 4012 added. This has no 4012, just the pure white after giving the master bottle a really good shake. My e'tac PS (which I have gone back to for now) won't seperate like this, even after a month of sitting. The illustration paints (all of them) are very, very thin already compared to e'tac PS & EFX, Golden High Flows, and Wicked that I have on hand (the Wicked doesn't seperate either). So, did I get a bad batch? Does your illustration white seperate like this within a day? If it's not normal I might contact Coast & Createx simultaneously.
