Default Re: cow licks

ok, stick it in a large plastic washing tub--bash the sucker with a hammer till knuckle size pieces--put knuckle size pieces in coffee grinder and grind to finest dust--now transfer a kilo to a 4 litre glass beaker and add 2 litres of metho alcohol--pour through filter --do that once more--then throw out and put another kilo in--new 2litres and filter--keep going until yourve done ten kilos---freeze solvent for 3 hour--refilter--evaporate--see what you have--maybe an acetone wash---id like to see it myself--so i could decide--i think id do an a/b extraction--then have another look at it--at this point i might do alittle reduction see how it comes out--you must play it by eye from here----where did you get the cowlick---whats its brand name--give it to me--good luck
