I am also aware of potters that score the greenware and then fire it. After the clay is bisque fired they inlay underglaze into the carved lines. Once the underglaze is dry they sand down the unscored areas to remove excess underglaze and clay debris. The approach taken is a personal choice. As are the tools that potters use to incise the clay.

Any cast iron vessel will do, or you could create your own special design using a delft casting method. This method incorporates simple clay sand casting with precision design including pouring channels. The compact nature of the sand doesn't allow the liquid gold to push its way down and thus it pools and cools in the cast.
Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains.
