Metal Shavings:You don't want fine metal filings, nor do you want large pieces of metal. Quarter-inch-wide aluminum curls are very common and very effective for use in orgonite, but any kind of copper, iron, brass (including brassed aluminum), bronze, nickel or even steel shavings will work fine. Just bring a bucket and some work gloves to a local machine shop and ask them if you can fill your bucket with metal shavings. Before giving them to you for free, they will probably ask you what it's for (typically more out of curiosity than anything), so why not tell them?
Crystals: Any funky, ugly, smokey pieces of quartz or other crystals will work perfectly for orgonite field devices. You can usually find this grade of crystal very inexpensively at most decent gem and mineral shops, or you can it from online vendors.
Fiberglass/Epoxy Resin: The most expensive component of orgonite. Any kind of organic resin will work fine, but liquid resin will be the easiest to work with for creating orgonite. Resin requires a chemical additive called a hardener, typically included if purchased by the gallon, in order to catalyze the curing (hardening) process. The orgonite may take multiple days to harden, so have patience.
Molds: This depends on the specific type of orgonite device you wish to create, but any mold which can withstand boiling temperatures should work fine. Avoid plastics unless they are oven-safe, as the chemical reaction which occurs during the catalyzation process heats the resin to temperatures which can easily melt normal plastics. Generally, metal molds or silicone molds seem to work best for most purposes, you can buy these cheap on the internet for instance on ebay.
Other Stuff: You will need to brush the indside of the molds with some kind of oil (sunflower, coconut, rapeseed oil or any other) before adding the resin. You will want a mixing container such as a small bucket (preferably with a pouring lip), a wooden stirring stick, some old rags or paper towels for splashes and spills, and a large, flat surface for leaving the orgonite to cure.
Safety: Organic resins emit toxic fumes before and during the curing process, so working in a well-ventilated area such as a backyard or porch/deck is ideal. You may also want to use protective gloves and wear clothing you don't mind getting catalyzed resin splashed on, as it will go everywhere.
