An example of how a liner glaze can meet another at the rim of a piece. This it quite simple to do. The technique is especially practical where mug walls are thin and cannot absorb enough water to dry the glaze after immerse-dipping. It is essential where the outer glaze is potentially leachable, or it might craze (which tenmokus often do). Thus, that straight line at the rim is not only a decorative element, it is the spot where leaching, crazing, staining and cutlery marking stop.
Liner-glazing ceramic ware is a very good way to assure that your ware has a durable and leach resistant surface. It also signals customers that you care about this.
