Re: How do you make orange blossom water?
To build your own still is no problem, even with kitchen staff you can get a good result. A laboratory flask is not a good idea because the flask is too narrow, parts of the steam will condense on the inside wall, resulting in losses of quality and amount. Distilling app. 500 g lavender you get 10 ml essential oil.
The best book for distilling essential oils at home:
The Essential Oil Maker's Handbook, Spikehorn Press.
I'am an Austrian engineer, offering know-how and all the staff like water steam copper stills to make your own essential oils at home. Since 12 years we offer workshops for distilling essential oils, we also have a book about distilling the oil.
This is all in German, but since three weeks, the book is also available in english.
further our seminars - we have english online seminars on our "distilling-fermenting-seminars-dot-com" Homepage
