Importance of opacity

I always encounter people who dabble in polymer clay work sometimes that their colours darken after baking or dont stay true. This is usually because of the opacity of the colours and it can be corrected simply by adding white specifically opaque white.
Working with Cernit, I have to stress the importance of buying the opaque white which will help in improving the colours. the picture below shows Cernit's white before baking and after baking on the right. As you can see, the white is darkened by the black slightly before baking and worsens after baking. the left cane uses an opaque white and the colours did not alter.Cernit do have an opaque white. Try to go to specialized craft shops instead who may have a wider range available.
So look for the "opaque white" Cernit instead of the normal "White" if it is suitable for your application where translucency is not wanted. Here are some simple canes I made.
If you dont intend to use white in anyway for your canes, it is still advisable to use opaque white as a background when you apply your cane slices. like these hair clips that were made, they all have a white background.
Oh and as usual, I am back to doing the market starting today til sunday at Trastevere, Piazza Sidney Sonnino so see you there!
