Separating how, exactly?
There’s a continuum of behavior you get from a pressed powder formulation as you increase the pressure and the dwell time, ranging from too soft/bubbled/unable to hold in the pan, to good performance, to too hard/glazes, unable to get product back out of the pressed cake.This must be well-tested in the lab before you go into production.You should know how your powder behaves at a range of psi and dwell times.As you adjust the pressure up, If you don’t get to a good-performing spot, or if your good-performance window is too narrow, you have a formulation problem that needs to be fixed.Can’t really help past this unless you post the entire formula.
