When making alloys in the high furnace such as steel or knightslime, as long as the appropriate additionally ingredients are present i.e. redstone, sand, gunpowder for steel, then steel will be made. Regardless of what is being melted, including such silliness as rotten flesh which normally becomes blood, can now be used to make steel.

Huh, how about that. Looks like I missed a set of parenthesis

Probably in the next week or two, have a couple other things I want in before the next build.

Thanks for responding so quickly. Is this likely to be posted to curseforge anytime soon?

Thanks mate, great work!
