Also I wrote a long wordy post on bangle problems - blogger has probably chosen not to publish it cause it was too long and boring! I will try and summarise it this time round.
I have trouble making solid polymer clay bangles, the often seem to break easily. At first they seemed to break at the join so I now add a bit of polypaste and make sure I smooth the seams carefully. That solved the popping at the seams but now means they break elsewhere instead! See evidence below
This bangle is made from a sausage of well conditioned Kato clay joined carefully with some polypaste in the join, covered with a decorated sheet of cane slices, baked on an empty coke can at 150oC for 1 hour. It looked fine and felt strong so I wore it for a morning. All good until I decided to sand it. Almost the minute I started gently sanding with my soft micromesh cloth draped over my fingers it broke. It is quite skinny, about 8mm in diameter, like some others I have been wearing which are fine - here's a post about them.
So where am I going wrong with them? My husband has a feeling that baking them for a long time they are strong but brittle and I should under cure them rather than cure them for longer so they are more ductile, less brittle. I was about to start some baking trials for different times when I came across a post from Tony Aquino on the Kato Polyclay Facebook page stating that the higher the cure temperature the stronger the clay will be. I will try and test some different temperatures too. What I need for bangles is something with a little flex I guess. I've had a few suggestions from clever people at the PCC Forum to try out. I will report back with anything I find out, but please leave a comment or mail me if you have any ideas I could try to make bangles that don't break!
