Rare ANTIQUE TERRACOTTA Clay Pottery SAD IRON 5″ x 4 1/2″ Forged Iron Nail. This sad iron is unlike any we’ve seen before! Appears to be made from a terracotta clay colored material with brown glaze. You can see the terracotta color showing through in areas. We read that very early Sad Irons were made from Terracotta, Clay and Pottery. See a small part of an article we found online on our last photo where it mentions this. The clasp is held in place with an iron nail that has a cross cross design on its flat head. The top part that lifts, is held in by wire. It is in excellent condition for age, it appears chop free and free from cracks. There are some areas as mentioned where either the brown glaze didn’t cover or it wore off and you can see the terracotta clay color.
