Why would you need a steam distiller?
-Steam distillation is the main method of separating essential or volatile oils from plant material, however commercial steam distillers cost around $400 and essential oils cost a lot too. With this Instructable you can start producing essential oils for less than $40.
Step 1: Introduction
Basically steam goes through plant material, where it absorbs the essential oils, then is condensed and the oil is separated from the water.
Step 2: Materials
-A teapot (or any vessel that will generate steam)
-A piece of pipe that will fit over the neck of the teapot.
-An elbow joint (same width as the neck pipe).
-Reducers (I'm not sure what the actual name for these is, they make the width smaller, these aren't necessary if the condenser pipe fits with the elbow joint).
-Another wide tube or pipe (this will be the outside of the condenser and needs to be shorter than the condenser pipe)
-A pipe that will fit inside the wide tube (this is the condenser pipe)
-Lots of innertube or some cement (for sealing the condenser
-Bronze wool (or some other filter material)
-Thread tape (not necessary but helps)
-A coat hanger and weight
All of these except the outside of the condenser should not leach in steam (use galvanized pipe),
To distill essential oils you will also need the material that contains the oil, this can easily be bought, found or grown. And something to collect the oil in.
