Now it was time to cast the actors ears.
For this I built a small plastic box that I could glue around his ear and
easily cast him using alginate. |

Here I am filling the mould with Ultracal 30 and will get a perfect
duplicate of his ears in plaster. |
I wanted to make a simple mould. Ear moulds can be extremely
complicated due to the fact that ears are nothing but undercuts. I filled
the back of it and the ear hole (is there a proper name for it?) with Roma
clay as seen on the picture.
After doing this I moulded it with alginate and plaster bandages. The result
was an plaster ear almost without undercuts. The only shortcoming of this
technique is that the foam piece doesn't fit beautifully behind the ear but
in this case the wig will cover this defect so I decided to use this simpler
kind of mould anyway. |

Here I have sculpted the tips of ears and the overflow. The round holes
are called keys and the use for them is to give the finished mould a good
grip to the other half. |
| Now I am ready to make the mould. I have built clay walls to
make a shape for the negative plaster mould. To make the separation easier I
always spray a little silicon on the sculpture. |
|
|
I filled the moulds with Ultracal 30 just as I did with the face piece
and after 2 hours I pried them apart and it went just fine. No undercuts at
all! |
I have now sent the actor to the optician and have ordered
lenses. I have ordered "crazy lenses" for him.
On this picture I have tried them on myself. They come in several different
models and cost about $150 a piece. Don't they look great? |
