Horn for a Unicorn
What makes a unicorn a unicorn? Why the horn of course! I am making the head of the unicorn needle felted wool over a styrofoam and steel base but I needed to make a horn. Wood? Wool? I settled on resin. I had to carve a model out of clay and then make a silicone mold over it and finally cover it with a plaster mother mold before casting.
I made a lot of samples and tests. The first resin I used (Which I have a lot of that I need to figure out how to use up soon before it goes bad.) comes out too yellow and is supposed to be either colored in the pot or painted afterwards. I didn't want to paint the horn so I used a different resin from Smooth On that ended up being a nice white. There was a big seam line on the horn that I cleaned up with my Dremel, but the whole thing still needs to be polished and sanded a little more.
Safety first! I had to use this super duper respirator for all the resin casting and a dust mask for the plaster and then the sanding of the horn.
