How to make a Ceramic Clock
Here are some simple tips to go along with the video. Feel free to ask questions for clarification!
It is important to compress your slab before texturing. This step also smoothes the surface so that the impressed textures show cleanly.
Using a large piece of paper below your slab allows you to slide it onto a bat without bending the clay. This will help avoid warping as the clay dries.
I create my own unique textures by carving patterns into a printmaking block. You can find linoblocks and gouging tools at most art stores.
You can use any type of circle template. This is a needle point frame I picked up at a craft shop. Using a hollow template is beneficial so you can see the pattern as you arrange it in a pleasing way.
When the slab is leatherhard, use a drill bit a size larger than the bolt in the clock mechanism. This will allow the clock part to fit after the clay shrinks through the firing process. Don`t worry if it is slightly too large since a washer is included with the mechanism to cover the hole upon installation.
Rasp the edges of the slab to clean any burrs that were left from cutting with the pintool. This will also create a sharper 90 degree edge.
Choose a glaze that accentuates the relief textures. My Waterlily glaze is formulated to puddle a smoky blue color in the recesses of the texture. Remember to glaze the side edge to create a professional finish.
Clock parts can be found online or at many craft stores. Ensure that the centre bolt is tall enough to fit the thickness of your slab. Most mechanisms have a built in hanger or come with a hanger attachment piece so the clock can hang easily from a nail.
