The Flux throwing ribs for potters are made of cellulose acetate, the same bioplastic used to make playing cards and photoraphic film.
The material and the thickness we have chosen to make them out of provides just the right amount of stiffness for potters to throw and shape any form.. They have a slight flex to them when pressure is applied.
A variety of shapes and sizes are available.
