Assume much?
It's not just using high heat, if you get distracted and let these pots run dry at medium heat the enamal starts chipping off.
It's a cast iron pot, give me break sometimes you may drop the ball but with these one little mistake and what is an extremely expensive pot is tickets.
And why use enamel inside a pot when it can't handle the expansion, which is really the basic issue, the disadvantages far outweigh the advantages of using it.
Even if you religiously look after these pots with age the internal enamel becomes worn out, discoloured, pitted. In that respect they are more a novelty than a tool.
