The first known pieces of Bunzlauer stoneware dating back to the 16th century were crafted by hand and decorated with a folk-art stamping technique using potatoes. Original designs were inspired by the peacock feather using the colors of cobalt blue, sage green and ferrous red. These designs and colors are still the inspiration for modern day patterns. Today, skilled Polish artists still individually handcraft, and hand decorate each piece using small sponges to stamp each pattern and color. After the process of mixing ingredients, molding the pottery, applying the decorations and glaze, the pottery is twice fired. This process makes the pottery extremely durable. The back is signed by the artist. The sticker indicates it is "Original Polish Pottery" "Ceramika Boleslawiec " "Hand Made in Poland" Plus, it is just gorgeous.
