Isabelle As soon as you make a few of these you will be an expert

Alright, for the regular Orgonite:
Two kind of matrix, one is the polyester resin, and the other is epoxy resin, one (the polyester smell terrible and is toxic) the second (epoxy) do not smell
The price of the two is about the same from US composites, except for the really inexpensive polyester resin that is roughly $25 per gal. as the other polyesters and epoxy are in the same price range 34 to 38 per gallon, when you buy a greater quantity they wont charge you as much, I just got 10 gal of epoxy : one to one ratio thick epoxy#150 for $278, that makes it $27 per gallon, if you get only one gallon it will cost you $38, so considering all factors, I rather use the epoxy.
For the metals you have many choices, but the smaller the better, any oxides will work especially well, but at this point you must use crushed crystal for thorough dispersion, otherwise a single block crystal is not going to give you the full strength within the device, to get the oxide really cheap go there:

This is the place where you will find the iron oxide at $1 per pound, and these are the best prices, you can mix with it some metal shavings, no problem, with or without.
If you are going to do only with the powder, one thing to remember: you will not need that voluminous of a device because with the powder it is quite strong.
For the proportions, this is what I do, say I am going to make a few pendants; in a small container, such as an old yogurt container, you will put 1/2 a cup to 3/4 cup of resin (mixed) so if you use a one to one ratio of epoxy, you would put in 1/4 cup of one and 1/4 cup of the other, mix them really good before you put in anything else
Then ad your oxide and your crushed crystals one to one: one Tbsp of oxide, one Tbsp of crushed crystals....two of oxide, two of crystal.... three of oxide....... in other words, equal amount of each, when the mixture is thick and a little difficult to stir, this is when you pour it in the molds.
For mold to make nice pendants you can use the mini muffin molds, there is 24 small muffins hole in it, so you can pour (with a 1/2 cup resin) about 6, do not fill them or they may be too thick to have hanging around your neck.
When you do devices with epoxy it is good to always have another container ready to receive your extra resin, like a large cone, and after awhile it will be all filled up then you have another device without wasting anything.
Are you OK with what to do for lubricating your mold, if not let me know and we shall help with it
If you can get silicon molds they are the best since you do not have to lubricate them
Good luck, please ask questions before you get in trouble
