Methods for improved atmosphere control through secondary gas pressure wave firing

A method for firing ware in a kiln, the method comprising:

• positioning at least one stack of ware in a ware space of a kiln, the stack of ware comprising a plurality of ware articles arranged such that at least laterally adjacent ware articles are spaced apart;
• heating the at least one stack of ware in the ware space of the kiln;
• introducing a first gas into the ware space on a first side of the at least one stack of ware at a first flow rate FR1, and introducing a second gas on a second side of the at least one stack of ware as the stack is heated at a second flow rate FR2, as the stack is heated, wherein FR1≠FR2;
• and
• adjusting the first flow rate FR1 of the first gas to create a pressure differential across at least a portion of the at least one stack of ware such that at least some of the first gas flows laterally through the at least one stack of ware.
