A continuous supply of fuel is needed for firing, as wood thrown into the hot kiln is consumed very rapidly. Stoking occurs round the clock until a variety of variables are achieved including the way the fired pots look inside the kiln, the temperatures reached and sustained, the amount of ash applied, the wetness of the walls and the pots, etc.
The solar simulator standards have some requirements for where the illumination spectrum must be measured. For example, the IEC 60904-9 standard requires that the spectrum be measured at four different locations in a pattern given below. [17] The measurement pattern required for spectral match measurements under IEC 60904:2020

The Japanese noborigama kiln is an evolution from anagama design as a multi-chamber kiln where wood is stacked from the front firebox at first, then only through the side-stoking holes with the benefit of having air heated up to 600 °C (1,100 °F) from the front firebox, enabling more efficient firings.
As high temperatures were necessary, the open end was of small diameter and chimney-shaped to conserve heat and to induce greater draught through the kiln. Layers of limestone, shale, and timber were hand-packed in each kiln, leaving space for a flue. The doors were then sealed and the kilns fired. The resulting batch of clinker was then removed.
