Coils The spiral and coil form can be found in many cultures: Celtic, Japanese, Hindu, Australian aboriginal, Arabic architecture and African art to name a few. The spiral is a positive symbol that belongs to everyone and excludes no one! This flexible, rubber texture plate is a symphony of spirals; use a complete spiral, a portion or a strip of this texture plate for your texturing pleasure!! There is definitely a theme of curves and patterns on this surface-lots of movement! You can see the example above that I fired in bronze clay. Metal clay and polymer clay enthusiasts alike will find it useful. The design surface is 10 cm X 11.5 cm / 4” X 4.5” and the depth is approximately .5 mm. Nice and large if you want to make large or longer things.
