Really screwed up the mix
 
I decided to make my first batch 5 gallons in case I screwed it up. Well, I did.
I started out not putting in enough KOH so with your collective help, I ran it again and added more KOH. I let it sit in the separator and I did notice glycerol on the bottom of the sample bottle. I ran a titration 3 TIMES and it checked good. I had a family emergency so I didn't get any further for several weeks. Today I finished the process.The glycerol was in gooey clumps so I scooped them out of the bottom. I reheated to 100F,filtered through a 5 mic bag filter and attempted to remove the methoxide. THERE WASN'T ANY. I attribute this to running the batch twice and letting it sit for several weeks. OK no problem. I put in mix tank and used the following formula. 5 gal BD=36# 1% of 36 is .36# .36#= 5.76 oz. With that, I added 5.76 oz of magnesol and gently mixed for 1 hour. I then attempted to filter through a 5 mic/1 mic filter bag. It took 2 hours for 1/2 gal to drip through the bags. Obviously I have done something wrong. It is only 5 gallons. Shall I dump it and try again? What did I do wrong. Sure glad it wasn't 100 gals like Fab's first batch.
Sorry for the lengthy post but I need help and I know you want to know everything I did or didn't do. Thank you in advance for your help. Tom

You just had to remind everybody about my first disaster didn't you Tom :)

When you say you attemped to remove the methoxide, how did you do that?

Did you pump mix the magnesol, or Stir it gently?

I would junk that test and try it again..................

Sorry Don, but misery loves company. Anyway, it is because of your experience that I tried a small batch. Thanks for that.:)
I SLOW mixed the magnesol. And I used YOUR method to remove the methoxide with the BD at 100 deg.
I noticed the inside of the 5 gallon pail WAS painted and now the methanol has stripped it clean. Do you think the paint is messing it all up?

Don, I sent you an email concerning this. Tom
