Potassium feldspar is an essential mineral in ceramics, used as a flux in glazes and clays. Its high potassium content lowers the melting point of ceramic mixtures, facilitating vitrification at lower temperatures. This improves the efficiency of the process and the quality of the finish, creating smooth and shiny surfaces, especially in fine ceramics such as porcelain.
In addition to its function as a flux, potassium feldspar improves the thermal stability of ceramic pieces, helping them resist temperature changes without warping or cracking. This makes it a key component in high-end ceramics, and in industrial products that require durability and thermal resistance.
Interesting Fact
Feldspar is one of the most common minerals in the earth's crust and occurs in various forms.
Helpful Tip
If you want to obtain a glossy and resistant glaze on your pieces, add potassium feldspar to your recipe. However, be sure to adjust the silica content in the mixture to prevent the glaze from becoming too fluid during firing.
