Please note I'm no professional and can't recommend any of my methods.Was this one made with a mesh and semi liquid concrete? Do you mind sharing your mix proportions?
No steel mesh in that one, I can't remember if I added a layer of fibreglass.
Made using a newspaper ball with left over motar mix while working on another pot.
I don't messure out I just add water till I get the texture needed with the mindset more water equals less strength.
See the cavity from this attempt with a ball of newspaper on top of a tin, this one has fibreglass, will add more shape and texture later.
