it would be the hardest breakable element. dropping thunder on it would only move a few particles. also it can't be heated by any other element only give of heat so to decide it's heat you have to use the heat tool. I think this has been made but it should really be added into the powder toy. maybe if it reaches 9000+ temp it will violently catch fire and give off plasma or some thing.
If you want I'll make it when I've fixed my mod which might be awhile, but when I do release version 4 of my mod I'll put this in. Also what should it break into? And should it be vulnerable to acid? I can do all of your requests so if you want this element keep an eye on my mod page.
i think the way cracker did it was cool it didn't break into any thing it just got moved a bit. i don't know i was thinking about acid but i couldn't think what it should do to it, maybe something different then just being dissolved.
