From Don Croft's Gifting Compendium:
1. I use non-stick muffin pans but of course the resin contracts as it cools, so even the cheaper ones work fine.
2. While you're in MalWart getting those pans, and if you don't have any little pieces of quartz on hand, go to the craft section and get the mesh bags of tumbled rocks (the smaller rocks). Pick out the quartz and other crystals. You can also get bits of quartz from the soil or streambed if you have a clue what to look for. The cloudy, even white, broken bits are just as good as a ten dollar Herkimer Diamond, of course, for this application.
If you opt for the dollar bag of MalWart polished stones and are unsure that you can spot quartz on the ground or creekbed, find the ones that are semi-transparent and/or dirty-looking inside. The white ones are often just marble, which is not as good as quartz but is adequate for TBs. You can get suitable quartz crystals by the pound from Gladys Bridges
. but I mention WalMart to show you that it's not hard to find ingredients. Gladys sends out distinct quartz pieces that are between a quarter and a half inch long. You get a LOT of crystals in a pound.
3. Drop a small xtal in each muffin mold. I often use a broken just a dirty, broken crystal chip about the size of your little toenail but if you're new to this you likely won't feel confident doing this. My confidence is based on a couple of years of towerbusting experience, so I know that a TB with a funky little chip will bust an average Entropy tower and I'm stating it for the record.
4. Fill the molds almost to the top with loose metal. Remember that 3oz is sufficient and that the molds are each 4oz. I want you to get the absolute most bang for your hard-earned or even lazily-obtained buck. 3oz of orgonite in a holly or juniper bush is sufficient for busting most of the single transmitters you'll encounter and even for turning those frowns of a chapel-full of devil-hating churchgoers upside down.
5. Pour the resin in by stages until it comes almost up to the brim of the mold after you've put the metal and crystal in. If the metal is too fine to permit the resin to soak through before hardening, mix the metal with the catalyzed resin, then spoon it in like you're making cornbread. You're probably going to learn the hard way to mix in the catalyst first.
I'm still learning that lesson from time to time ;-)
6. When I'm going to toss out a bunch in town, I paint them green and brown (camo scheme). You'll be surprised how difficult these are to find once they've been tossed.
