Making your own bisque hump or slump molds is probably the easiest and most accessible way to get into mold making in ceramics. All you do is create a prototype form that you can slump a slab of clay into or over, bisque fire it and presto! You then have a durable hump mold you can use over and over without even touching a bag of pottery plaster.
In this video, which is compiled from Kari Radasch’s Low-Tech Clay: High End Results, we have compiled three interesting ways to come up with your own custom bisque molds in whatever shape you can dream up. Have a look and then start thinking of your own custom shapes! – Jennifer Poellot Harnetty, editor
