Slip
Slip is a liquid mixture of clay and water that is used in various applications within ceramics, including bonding, decoration and molding. This liquid suspension allows for easy manipulation of the clay, facilitating bonding and the creation of complex shapes with high precision. In the bonding process, slip acts as an adhesive, especially useful for bonding parts of a piece of clay that is still wet, such as handles on cups or decorative details. In the casting process, slip is poured into plaster molds to create hollow pieces, which are then dried and fired.
Slip is essential for techniques such as slip casting, where a liquid suspension of clay is poured into preformed molds, allowing it to solidify and take the desired shape. In addition, slip is used in the application of engobes and liquid decorations, allowing for an even distribution of colors and textures over the surface of the ceramic.Interesting Fact
Companies such as Wedgwood and Royal Doulton took advantage of slip casting to establish quality and reproducibility standards in the ceramic industry, consolidating their presence in the global market and democratizing access to high quality decorative and utilitarian ceramics.Helpful Tip
Keep the slip in a fluid and homogeneous state, stirring the mixture regularly to prevent clay particles from settling to the bottom of the vessel. Use fine sieves to filter out impurities and ensure uniform suspension of solids, which will result in pieces with sharp details and a smooth surface.
