Our flake shellac can be used in several ways. You may place flakes directly into the pad cup, then heat the cup to melt the adhesive. You may choose to make your own sticks as I did in my early career. You may dissolve the flakes in denatured alcohol to make liquid shellac. Liquid shellac can be used to glue pads in (a squeeze bottle works well). One can use liquid shellac to glue adjustment shims and flute pad shims.
