RE:pigment extraction

After experimenting with various oils I settled on clear lamp oil. Its light and has no intrinsic colour to confuse results and is cheap and readily available. Also no emulsion reactions with methyl hydrate (paint thinner alcohol) which can confuse results. Resulting mash should be filtered. I use coffee filters. Cheap and readily available. 

If you are not sure about what you are getting try using different original solvants.  That is mash up in distilled water for first try. Another petal in alcohol and possibly a third one in oil at first allthough this is a bit heavy so doesn't filter as well. Then mix solution with an other solvent and shake well.  The solvants I use work well together .I never would use cooking oil. Too heavy, has emusions with a lot of alcohols and has a tint which makes it hard to properly view extracted pigment.
