Metal Rigid Ribs
Ribs are a potter’s best friend when it comes to defining profiles, wringing out water or adding manipulating profiles. Metal ribs, while suitable for throwing, are commonly used in handbuilding for their ability to scrape clay and compress seams.
There are many functions that ribs perform, which is one of the reasons they’re so important. The most common uses for ribs are for and removing throwing marks while compressing the clay, removing excess water and also provides a way to get sweeping curves on bowls and platters.
Medium to larger bowls really benefit from this tool.Using a rib for the inside profile of a bowl can assure a continuous line from the bottom through to the rim. And using the same profile repeatedly helps in making multiples for sets.
