Vitrifier
A vitrifier in ceramics is a chemical agent added to clay or glaze mixtures to promote vitrification during firing. Vitrification is the process by which clay is transformed into a hard, non-porous material at high temperatures, developing properties such as water and wear resistance. Vitrifiers help to reduce the firing temperature required to achieve complete vitrification, improving the efficiency of the process and the quality of the final pieces.
In addition, vitrifiers can influence the texture and finish of the ceramic, allowing for better adhesion of glazes and a smoother, more uniform surface. By controlling the amount and type of vitrifier used, the properties of the clay and glazes can be adjusted to achieve specific finishes and optimize the functional characteristics of the parts.Interesting Fact
The discovery of the use of vitrifiers in ceramics was a milestone that enabled the development of porcelain in China during the Tang dynasty (618-907 AD). By adding feldspar to clay and glaze mixtures, Chinese ceramists were able to produce translucent, vitrified porcelain pieces at very high temperatures, revolutionizing global ceramics.Helpful Tip
To maximize the effectiveness of vitrifiers, adjust the amount used according to the type of clay and glaze you are working with. Experiment with different combinations of vitrifiers and firing temperatures to find the formula that best suits your artistic and functional needs. Also, test fire to see how glazes affect the texture and strength of your pieces, allowing you to refine your techniques and compositions.
