Feldspathic ceramic with a low melting point and reinforced with leucite for the coating of lithium disilicate ceramic structures reinforced with zirconium dioxide, such as Celtra Press. Advantages: highly aesthetic coating with a vibrant and realistic appearance, optimized for adhesion with Celtra Press and lithium disilicate – no initial firing required, stable and robust results even after multiple firings, high chromatic fidelity, and easy handling.
