I've already told my closest friends who I trust to support me if something should go wrong. I have a very high chance of miscarriage due to some health issues.
I won't tell family until past 13 weeks. Hopefully I can hold off and hide until 20 weeks, which would be my ideal.
Most cast iron is made to withsatnd the tempuratures of a camp fire. I would not reccomend putting it deep inside the raging fire or anything, but they are made to work over a real fire. Which is why most good camping pots/pans/griddles/dutch ovens are cast iron.
Mine started out like that, but now it is a beautiful black shiny color almost like cast iron. I have never been shy about getting it wet to clean it, but only when it is completely cooled off, and of course never with soap, just hot water and a flat edge scraper.
