The Wedgwood scale, also known as the Wedgwood scale of firmness, is a qualitative scale used to assess the hardness or firmness of materials, particularly in the context of porcelain and ceramics. It was developed by the English potter Josiah Wedgwood in the 18th century. The scale is not widely used in modern scientific contexts, but it can give a general idea of how the firmness of ceramic materials can be categorized.
