Aztec is one of the few designs Charlotte created for Crown Ducal fancies that is not inspired by plant form. This relatively simple design and its popularity probably explains her motivation to create the Stitch pattern, (3274), later that year with the same colour palette but with a much simpler design for quicker tube-lining. The tube-lined step and rectangle motif of Aztec was simplified for the tableware patterns 3213, 3219. 3220 and 3223.
Production of Aztec continued into 1935 with just a few examples having the period 2 backstamp, but no examples have been seen on the new shapes introduced in 1936.
