We make stoneware Salt Glazed pipes and fittings by coal firing method. Since we donot get good colour on bottom rows in our down draft kilns we tried to experiment with using GERU i.e. clay with high iron oxide content. This gave very good results but we are being told it will be considered as glazing and not colouring. We need the clarification whether applying clay with high iron oxide content will be taken as glazing or colouring and whether this clay will be called glaze or colouring agent?
