Welcome to Librarium Online!
I've been reading a lot about making silicone molds and there seems to be some hinting occasionally about the vulcanization process possibly altering (destroying?) some of the details of the green. There's very little about it, but people have mentioned making swords wider than desired or bubbles trapped inside the green causing problems. Does anybody have any info on this?
If you use a Room Tempature Vulcanizing (RTV) Rubber specifically made for casting delicate parts, then you shouldn't have a problem. If you use a heavier duty RTV rubber, one that is designed to cast metal parts such as gears and what not, then you might have issues.
If you go to Mold Making, Mold Rubber and Casting Resins From Smooth-On, run through their product list and download the pdf's for the dif. types of rubbers, it will tell you how much heat they will give off during the vulcanization process. As long as your greenstuff can handle the heat, then you're okay. Side note, greenstuff can be purchased from other vendors like TheWarStore.com as "green/blue kneadalite putty". It is EXACTLY the same as GW greenstuff, but in larger qty's for the same price. It should also have info on the temp it can withstand.
Hope this helps a bit.
Here's what comes up when you tap 'vulcanization' in to Wikipedia: Vulcanization - Wikipedia, the free encyclopedia
Other than that I can't say anything else as I know very little about moldmaking. Sorry
Sorry about the double post!
Well it looks like my advice has been rendered useless by LuckyNo.5 Oh well.
