Preparation of Lithopone:
From a stability standpoint, lithopone, a fusion of zinc sulfide and artificially precipitated barite, is non-toxic and exhibits resilience to mild lyes and acids. However, it is incompatible with colors containing copper. Despite its strong covering power in oil, lithopone’s drying capabilities are notably limited, posing potential issues for artists. Notably, early experimentation with lithopone-based grounds instead of zinc white resulted in undesirable darkening, although this blackness receded upon drying. This unpredictable behavior has sparked debate among scientific communities, emphasizing the need for further exploration and understanding of this pigment.
Lithopone is a specialized white pigment that has been widely used in various applications, including paints, coatings, plastics, and paper industries. Known for its excellent whiteness and opacity, lithopone is predominantly composed of barium sulfate and zinc sulfide, making it an effective alternative to titanium dioxide for certain applications. As industries continue to evolve, understanding the wholesale lithopone pigment pricelist becomes essential for manufacturers and suppliers alike.
