Looks like freebase? First try adding the corresponding amount of citric acid, if you have any, for a 1:1 molar ratio. If you need help with this, have a look for orchidist's salt calculator, there should be a link to that in my sig. Stir that up, maybe best with the beaker in a warm water bath, and with any luck the DMT citrate will dissolve into the PG. Then your e-juice will be ready for use.
Failing that, say if you haven't any citric acid or it just didn't dissolve, dump it all into a larger volume of water, adding acid if you haven't already, then treat it as a normal A/B extraction - basify to pH>=12 and pull with your choice of NPS.
Oh, I see you got water in it (sorry, ADHD skimming skills can be questionable
)
You can try the citric acid bit if that's still mostly PG in the beaker, otherwise do the A/B extraction using the water bath water as your acidic phase to combine with the beaker of borked juice. Did much of the juice end up in the bath?
The PG will dissolve into water but DMT freebase mostly won't. Just make sure you keep all of the water and PG and you won't have lost anything.
