Problems
G'day group
it is with great embarrassment that l have my
first post. For 3 months l have been doing test batches (lost Count how
many) and still cannot past shake test.
Methanol - From a drag racers 44 gallon drum -
best apparently
Lye - Tiny pearls 99+ - fresh - then
flake
Oil - supermarket virgin oil
Deep cooker filled with water with thermo
(bottling type to 120 deg. C )
Drill stand above
2Lt glass jar tall with narrow neck with screw
top lid with hole for paint stirrer
Have tried lots of combinations re
mixing time (1hr to 2.5 hr)
Mixing speed -
slow to fast
amounts of lye - 2.7g to 4.2g per
lt
amounts of methanol 200ml to 250ml per
lt
types of oil - canola , blended edible all say
100% unused
After process the product separates nicely and
after waiting 12-24 hours do shake test with rain water (all l have) usually
it takes hours to separate with a thick layer in-between of white fluffy
cloud like stuff (.5 inch thick)
The pearl variety of lye dissolves quickly but
is hazy whereas the flake is crystal clear. Am heating oil to 55 c then
adding methoxide then stirring maint temp throughout. Have read and reread
JTF site and archives but nothing leaps out as obvious, my process seems
correct, my materials seem correct but l'm starting to feel Very stupid. Is
there something on this side of the planet that l'm not aware of?. Also
would be very keen to talk - SEE setup working in Melbourne Aust. I'm in the
Dandenongs. Any advice would be appreciated, thankyou
Regards
Peter from Oz
