Lasittamisen

Lasittamisen refers to the process of applying a glaze to a surface, most commonly pottery or ceramics. This glaze is typically a vitreous coating, often made from silica, flux, and colorants, which is then fired at high temperatures. The purpose of lasittamisen is multifaceted. It serves to make the ceramic object waterproof and non-porous, which is crucial for functional items like dishes and vases. Glazes also provide decorative qualities, offering a wide range of colors, textures, and finishes, from glossy and smooth to matte and rough.

The application of the glaze can be done through various methods, including dipping, pouring, brushing, or spraying. Each technique can influence the final appearance of the glazed piece. After application, the object is fired in a kiln. The heat causes the glaze ingredients to melt and fuse, forming a hard, glass-like layer that adheres to the ceramic body. The specific temperature and duration of the firing process are critical and depend on the type of glaze and clay used, as well as the desired outcome.

Beyond ceramics, the term lasittamisen can also be used in other contexts, such as the glazing of windows, where a pane of glass is fitted into a frame. However, its most prevalent association is with the art and craft of pottery, where it is an essential step in transforming raw clay into durable and aesthetically pleasing finished products. The choice of glaze and the meticulous process of application and firing are central to the work of ceramic artists and craftspeople.
