Trimming
Trimming is performed once a piece has reached a leather-like consistency during the shaping process, usually on the pottery wheel. This procedure involves trimming off excess clay, perfecting the shape and refining the details of the piece, ensuring that it has a uniform thickness and a smooth, well-defined surface.
During trimming, specialized tools, such as knives, spatulas or scoopers, are used to remove excess material and adjust the symmetry and balance of the piece. This stage not only improves the aesthetics of the ceramic, but also strengthens its structure, preparing the piece for the subsequent drying and firing phases. By eliminating excess clay, the risk of deformation and cracking during firing is reduced, ensuring greater durability and strength of the final product.
In addition to its practical function, trimming offers opportunities to add decorative and textured details to the piece. For example, patterns, incisions or markings can be created that add character and personality to the work, transforming a basic shape into a unique artistic piece. The ability to perform precise and controlled throwing is essential to producing high quality ceramics, as it directly influences the final finish and structural integrity of the piece.Interesting Fact
In Greco-Roman ceramics, trimming was used to inscribe signatures, symbols or marks of authorship on the base of the pieces, functioning as a personal seal that made it possible to identify the provenance and authenticity of the archaeological objects found in excavations.Helpful Tip
Be sure to maintain a proper consistency in the moisture of the clay during trimmimg, as a clay that is too dry can fracture and one that is too wet can easily deform.
