This filter paper is used to filter expensive lacquers before use or after adding pigments, to avoid lumps and impurities in the lacquer later. To use it, you lay several sheets of paper (5-10) on top of each other and pour in the lacquer. Then you wring out the paper. The thin and tearproof chemical paper fibres are based on the mulberry tree fibres that were used in the past but are hardly used today because of their high price. 520 x 300 mm.
