Ignited HYGN and LOXY can melt through BRCK, METL, IRON and TTAN if there's enough of it. OXYG + HYGN reaction also ignites hot enough to melt the elements above^
You had me at flame, this could be a very good addition to TPT or it could just be another random element , but most of the elements are random, so why not?
I want it added because more elements means more elements, besides we only have 6 liquids that burn and none are that hot
