You've probably done your batch now! Hope it went well?!?
I've been experimenting with TD also, hardly ever used it before, have some dark green olive.......
(the control freak in me only uses this for batches that are getting pretty well coloured up!)
The stuff I've got seems to go either way, but I prefer water, it's instantly dissolved. I have never added to the lye water as didn't want to 'fade out' all of my colours, but recently tried a few mixes with TD in & hey, there's a whole new range of colours!!!
You probably won't have this problem seeing you don't gel, but I have had the 'TD crackle' thing happening in anything I want to gel (ie. CP embeds etc) so have come to the conclusion, TD = fridge/freezer. Unless I'm going for that 'crackle' look!
Looking forward to updates on your big batch
