What goes haywire when emulsion grows too old?

I mixed a batch of Speed Ball emulsion May 24. It's been in the fridge. I just burned and washed out a screen successfully. What sorts of problems will I encounter when the emulsion finally dies of old age? Hank

Your screen will just blow the fuck out. Use it all up on the quick.
