We heat the iron meteorite in an oven to a high temperature in a protecting oil which expands the cracks and allows a protecting oil to replace the moisture. The protecting oil prevents discoloration and damage to the iron which would occur if heated otherwise. It works perfectly. None of my iron meteorites rust. The protecting oil is then swabbed over the surface and allowed to evaporate for a few days, then the remainder is removed and the surface allowed to fully dry, protecting the meteorite from absorbing additional external moisture. Such an oil is ordinary ATF as used in modern automobile transmissions. (And it is cheap!) The method was developed by my son, Jim, and has been partially described in one of my previous articles in METEORITE TIMES (November 2002) in which we described proper preparation of the surface of an iron. The details using the AFT was not discussed there as it is a bit tricky and I am not suggesting that anyone try this as I don't want anyone to burn down their kitchens or blow their heads off, but with careful experimentation someone experienced in lab techniques can achieve much success. Heating carefully as described in the article should give good results. Other techniques have been described by various preparers and some of them seem to be successful as well. But each iron is unique and no method works exactly the same for any two. Ron Hartman ------------------------------------------------------------------ ok, folks what it is? let's see the TOP 10 sweatiest, crappiest, rustiest, hear-it-crackle- as it falls apart in your hands 5 seconds after sawing, skyrox. i'll start with: tsarev, brahin, campo. what have YOU got?! MT. DIEU... PEEEE-UUUUU ! Nearly impossible to cure. Steve Schoner/AMS ----------------------------------------------------------------- Yes, Jim and Ron's method does work. Regardless of what Steve Schoner said, I have a very nice full slice of Montdieu Jim prepared some 3 or 4 years ago, and it is still in perfect condition. It works!! Anne M.
