Types of Raku and firing techniques



Sacando RakúRaku is a Japanese pottery initially and currently spread throughout the globe technique. In the Raku firing is performed in an oven usually handmade, given the wear to receive this in cooking. Cooking is done directly with fire in the oven and preferably in a slightly reduced atmosphere. The previously cooked pieces are fired and are carried about 1000 ° C and that temperature is removed from the oven, cooled air directly or reduced by the action of smoke out of the oven.
