Homogenizer or mill roll
Hi All,
When making liquid foundation, is it better to use a mill roller or homogenizer?

Neither. It’s better to use a colloid mill, or a Cowles dissolver, or even a ball mill.
Homogenizer doesn’t have enough shear. 3-roll mill does not work well with water-based grinds.You can only get away with using a homogenizer if you dry-mill your pigment/powder mixture first, using a mikropulverizer, or a fitzmill, or equivalent. -
Thanks, where can I get a colloid mill or dissolver or even a ball mill?

Cowles, Hockmeyer, Shar, Ross, and Day are all manufacturers of this type of high-shear disperser. -
This is called a hammer mill. If you use something like this to dry-grind the powders in your liquid foundation, you don’t need the high-shear of the other mills to wet-grind those powders instead.
