Step 1: Roll Out the Clay
Roll out the clay until it's about a quarter of an inch thick. The amount of clay you require depends on size of the bowl that you're making.
Step 2: How to Get the Bowl Shape
You will need to use a plastic bowl you don't mind cutting up, I used a takeaway bowl I got from a ramen restaurant.
Using vaseline as a release agent, coat the plastic bowl with a generous amount. This will help with taking the plastic bowl out of the clay bowl
Step 3: Making the Bowl
Using the clay you have rolled out, cover the plastic bowl with the clay. Smooth down over the bowl and cut away any extra clay not needed. Leave until the clay bowl has completely dried, this can take up to 24hours.
Step 4: Remove the Plastic Bowl Mold
Once the clay has completely dried, you can remove the plastic bowl. You may need to cut the bowl with scissors an/or a knife. Be careful when doing this as it can be easy to break the clay bowl in this step.
Step 5: Sanding
Use sandpaper to smooth out any bumps or cracks. Then use a brush and some water to dissolve any dust particles left over from sanding, this will ensure your paint will go on smoothly.
Step 6: Painting
You're now ready to paint your bowl. I like to prime anything I paint with white to start off with and then paint colours on top. This will help any bright colours pop as they'll be on a white base rather than the terracotta clay base.
Step 7: Glazing
To finish off the bowl you can glaze it, I use triple thick glaze. You can brush this on just like paint and it leaves a glossy surface.
Leave to dry and your bowl is complete!
