Yeah, I think that is a more correct term and description, either way, burnishing or polishing to me seems to fill the poors and it don't season quite as well, but also modern "Cast Iron" isn't just the old time 4-5% carbon pig iron of old, it has some other alloys in it at least in some cases. Lodge uses I believe 25% scrap from a machine shop.
What ever it is, they cast better and thinner that the true 150 year old stuff.
