This is a rare find ! It’s a unique cast iron cauldron / kettle that has a base which inserts into a wood cookstove . We found this in our 1800’s Vermont farmhouse along with other cast iron pieces that came with the wood cookstove which we currently use . It is stamped with a number 7 on the bottom. It most definitely has cooked over many fires but shows it’s age gracefully . There is a small crack on the bottom ( about 1.5 inches , please see picture) which could be repaired for use or left alone as a display piece in a country farmhouse kitchen or made into a unique planter . I was intending to repair it however I need to thin out my cast iron collection . The kettle is 9.5 in tall with a 10 in diameter , the insert is 6.5 in in diameter and fits perfectly inside the top of most wood cookstoves. It has a strong wire coiled handle . Other than oiling / seasoning the pot , I have never cleaned it . I prefer the primitive natural look of cast iron but one could clean it up to shine .
