This is 4x500mg tablets of paracetamol with sodium hydroxide... for 1 hour and 15min, 20c as I calculated 3.6 tablets for 1+10 parodinal/rodinal based off given 'net data.

I didnt want to lose any, so I didnt filter it... and its interesting you mentioned sulphite in that way, as I read a common filler for paracetamol tablets is sodium metabisulphite and I read on APUG somewhere sodium hydroxide converts it to sodium sulphite.

So that gives me a good mind to go back and do my methylated spirits + coffee filter to take it out
I didnt have to do any channel swapping on this one, still very thin.
