Swim has a question for all beez that might have tried this:-
Hear in the U.K. it is very hard to obtain a suitable denatured Alc in large quantities due to licensing laws etc. Swim has pondered on what to do as Alc is paramount in phed extraction, plus it is also very easy to evaporate. Whilst browsing the shelves of chemists he noticed two types of Alc being sold:-
Mentholated Spirits – This was pink and full of crap to prevent it being drunk by alcoholics.
Surgical Spirits – This was not pink and full of crap, but contained a small amount of aromatic oil.
Through trial and error swim realised that ‘Meths’ was a definite no-go after he ruined a 10g phed extraction totally beyond repair
When ‘Surgical Spirit’ was used he found it to extract phed exceptionally clean, but that the 5% aromatic oil was left on top of the crystals. Swim has gently boiled the spirit for a very short period (to avoid excess evaporation) every time and skimmed the top patchy layer of oil away.
Swim would like to know if this small amount of oil would affect the LWR (36hrs) in a noticeable negative way.
