I was wondering about ways to fill cracks on part turned bowls. Has anyone tried any of the various ways of thickening epoxy?
I would like to turn casting epoxy into something the consistency of big boy filler or polyfiller. Fortunately I would like it to be kept black, not clear!
A quick look up suggests 5 possible options:
1) Polyester fibres eg:https://www.neillsmaterials.co.uk/product/epoxy-thickener/
2) Colloidal silica

3) Thixotropic silica
Unsure how this differs from the previous option. Possibly the seller just chooses to highlight a different interesting physical property of the same product

4) Microballoons
This sounds unpromising as it implies it won't leave a smooth surface.

5) Wood dust / charcoal etc
Any random powder as a bulking agent.
