Button shellac is hand made from the villages around Calcutta, it is therefore less refined than machine made shellacs, however this gives added strength to the polish film and for this reason is often used as a finishing coat for a sealing stain. A useful polish to have in the workshop, but should be used with discretion due to its colour. Avoid using it over darker wood as it gives a cloudy appearance and tends to hide the grain. The golden appearance will enhance some woods for example, Walnut. Based on a traditional shellac recipe. Manufactured in the UK by FLAG Paints Ltd.
