The present invention provides a seamless form system designed to encase stacked pottery forms, creating a seamless surface for molding clay. This invention addresses issues such as unwanted seams, form shifting, and moisture damage. These issues are prevalent in traditional stackable wood or plaster forms. By providing a unitary, continuous piece without joints or seams, it ensures a smooth finish in the final ceramic products and extends the lifespan of pottery forms. The system simplifies the pottery-making process, enhances product quality, and supports sustainable practices. Ideal for artisans and manufacturers, the system improves pottery and ceramics production by enabling the creation of higher-quality, seamless items with improved efficiency.

A mandrel suitable for supporting an airfoil preform includes a first piece extending along a longitudinal axis of the mandrel, and a second piece in physical contact with the first piece at first interface region and extending along the longitudinal axis of the mandrel. The first piece is formed from a first material, and the second piece is formed from a second material.
