By crushing finely gold leaves and mixing them with melted glue, a paste is obtained, broken into pieces and transformed into powder, called « Kindei » Gold Powder. First, the 0,2 micron gold leaves are crushed into 3 microns pieces. Afterwards, the glue is washed out with water and dried. The powder obtained is as smooth and fine as flour. By conducting researches over many years, Horikin created and developed premium quality powders.
