Maria Poveka Martinez was the master potter of San Ildefonso in her time. She is famous for her black on black pottery. She has passed this tradition down to her family members and anyone willing to learn. She starts by digging her own clay and firing it outside under animal manure to achieve the black color. This pot is signed Maria Poveka and has no designs on it. This may indicate that this was during a time period when she made pots without the assistance of her husband Julian or Santana, her daughter in-law. This plate has no cracks and is smooth on the inside. The bottom has some scuffs from being moved around. Although it is still in good condition and looks beautiful. A well handcrafted plate to add to your collection.
