A Reason for Magical Ores: Science Vs. Magic

[Lavastage]

Putting a koshamarite tile under a chemmaster would make it spit out the wrong reagents instead of the one you clicked on.

The way I see it, it would spit out random base chems, some intermediate ones (for instance, ammonia, or sulphiric acid.) and possibly some really bad mixes (like a combo of potassium and water)
That way, it would be easier to have accidental chemical reactions.

Oh no, instead of giving you some water for some obscure recipe, it made azide instead! OOPS.
