Hello Dear Sir,

I have recently discovered a store in my new neighborhood called, American Science and Surplus. Among the many fascinating items there they have chemistry equipment. I would like to learn how to extract oil essences from plants like lavender. Please send me a list of what I would need to do this with some degree of efficiency. Many thanks in advance.
