Hi Julian
This is my take on things , as any soaps or excess base is soluble in meth then while there is plenty of meth then the batch would look ok regardless of how much of the soap/ base is in the the batch and on testing would still give good results.
On removing the meth then things become apparent with physical problems. This was the good thing about a open top reactor , being able to do visual inspections to see what's going on.
If you have all the gloop out and can finish the batch then I would save the gloop for the next batch and put it into the feed stock before a Glyc wash, this way you get to use the base chem's but if it is soap (I'm not convinced that its soap and think its excess base ) then the Glyc wash after will remove the water thus releasing the base chem's.
This is just a quick jot on things inbetween a million other things going on. Plus as on iPhone can't see picks.
Phons on tomorrow if you want a chat
