Tips on making Postʼs Cone 1 Majolica Glaze... - Decide how much glaze you wish to make - When I make small batches of glaze I measure in grams. - When I make large bucket size batches of glaze I measure in pounds - it makes weighing go faster - Always add your water to the bucket first. - After the water, add the EPK, this is the clay and it helps keep the rest of the ingredients suspended in the glaze instead of settling out in the bottom of the bucket. - Decide which opacifier to use. Tin Oxide is more expensive but it gives a softer looking white. Superpax or Zircopax cost less and give a brighter white. Only add one opacifier to your glaze batch.

3 Chinese Porcelains influenced the development of pottery across North Africa and Europe 1000 years ago years ago Chinese porcelain pottery led to the development of a glazing technique in the Middle East that spread all across North Africa and parts of Europe. This technique is known to us as Majolica. Chinese potters discovered white porcelain clays in the mountains of China. They painted decorative blue imagery over this white clay. Moorish potters in what is now modern day Iraq and Iran were influenced by the Chinese porcelains that they saw being traded. Unfortunately for them, there were no porcelain clay deposits to be found in their region of the world. So they got creative and added tin that was discovered in Turkey into their glazes to make a white base glaze. They glazed their buff and brown clays with this white glaze and then painted colorful decorations over this glaze. In the Islamic religion images of the prophet Mohammed are forbidden. Because of this, mosques are decorated in floral and abstract imagery. The domes on mosques and interior tiles all are decorated with a white glaze that has colored imagery brushed over the top. As Islam spread across North Africa and into Spain, this style of glazing spread along with it. There is an island near Spain called Majorca. This island became a center for pottery production using white glazes with colored imagery brushed over the top. The world Majolica comes from the island of Majorca. As potters on Majorca exported wares across Europe, the Majolica technique influence potters in Italy and the Netherlands who produced their own versions of this type of pottery. In Italy, it is called Majolica or Faience. In the Netherlands it became known as Delft ware.
