Aiming at the problem of single deduction operation and loss of original artistic features in the process of pattern extraction and transformation of Cizhou kiln, the paper aims to propose a pattern deduction strategy based on shape grammar. Cizhou kiln patterns with typical artistic features are collected and a material library is established. The original patterns are deduced and transformed in combination with shape grammar, and applied to the design of cultural and creative products, and the design scheme is evaluated by fuzzy comprehensive evaluation. The patterns deduced and transformed by shape grammar not only retain the original artistic characteristics of Cizhou kiln, but also meet the modern aesthetic needs. The design scheme of cultural and creative products of Cizhou kiln has obtained high satisfaction. The feasibility and effectiveness of Cizhou kiln pattern deduction method based on shape grammar have been verified, and it also provides a new idea for the innovation and development of traditional creation.
