Make a box mold


1. Wooden model dressed
2. Set up the board walls
3. Divided into a half
4. Pour the plaster
5. First side
6. Second side



7. Last side (bottom side)
8. Complete mold








I tried making a box mold. The model was made of wood. You must give the model sphere (additional height according to the shape) like the pictures above. I made my own separator, a mixture of white soap and coconut oil. They were heated until homogenous mixture. The system of this mold was drained casting. I didn't have to pour back the waste slip into container, I just made a six holes for valve in the bottom. You don't have to drill the dry mold, just use wet clay when you are making the mold (fig. 7). 

If you try for slip casting, you should put the mold aboard the container using wooden props. When you have appropriate thickness, you just withdraw the valve from the bottom of the mold, so the slip will run down into container. If you have to lift and upend the mold that contain slip, it's too risky and potentially have different thickness.   

I've made some boxes from this method. But actually I felt this demonstration is too much. Beside the shape also the size. I thought, I've made something mission impossible. May be it has a good shape in drying or bisque state, but in high firing it will be collapsed or badly deformed. But the method of using valve in the bottom of the mold is applicable to the other shapes. Remember just for a big one. But if you like challenges and have better method, a box shape is a good choice.

Bali Trip





These pictures are Balinese traditional roof tiles. They are made by traditional craftsmen in Pejaten village, Tabanan, Bali. From Denpasar, it takes 45 minutes by motorcycle. In Indonesia language, the roof may be called "genting". It's made of local red clay. In Some Asia countries, genting is still used for building the house. Genting like a module and stacked each other tightly. For decorating, there are special forms. Those on the middle picture are usually put on the top of roof and the below one for edge of the roof.

Malang Trip




These pictures are the condition of craftsmen village in Malang, Indonesia. From Jakarta it takes one hour by plane and 17 hours by train. They use stoneware clay and high fired glaze. The product that they made were mostly by slip cast technique. They were really experts in making molds, from little ones until a big one such as vessel which is 1 meter high. But  mostly they produce souvenirs, with the big one as occasionally done. Because the policy of Indonesian government for conversion of gas to LPG, many factories got bankrupt. Today by time to time with government support they begin to exist again.
