First time making sprue goo, is this right? It doesn't feel right to me.

A little over a half bottle of my hobby cement. I cut a bunch of sprew into little pellets and dumped them in.

Periodically gave it a good shake (not sure if that did anything or was even needed) and this is it about 20 hours later.

Its one solid sludge on the bottom. Gray cement on top and the stuff on the brush feels like something I worry will wreck a model if I try to brush it on. It's super thick and stringy.

Is it supposed to be separate in the bottle like this? Did I add too much? Can I fix it?
