Maeda specializes in Iroe kin-gin sai (painted gold and silver color decoration) technique, which was originally developed in Song China (10-12th century AD), and then imported to Japan in the seventeenth century. After the first firing, the ware is re-fired with color glazes at a low temperature. Afterwards, gold and silver decorations are applied and the ware is fired again under an even lower temperature. Maeda uses subdued colors and abstract motifs to decorate his wares. They are wildly popular in Japan as table ware and are collected both in the US and Europe.
