Well after getting my fred pizza casting, i decided i wanted a more display friendly piece, the resin pizza was fine but a bit brittle, so i decided to cast it up and make myself a cold foam version, which would be cool for display as its lighter and if you drop it you don\'t end up with a jigsaw.
First up i ordered myself some silicone, and two kilo promptly arrived, poured it up and yup not enough!, so i ordered another two kilo and this just about done the job, once this set i made a plaster case mould so it would keep its shape, left it overnight and i opened it the following morning
This is what it looked like.

Then i mixed up some fast cast resin and got a resin pull out to check the details, the original is too the right

everything looked good so onto the next job the clay press.
I needed to do this so i could get a rubber version out, to do this i needed to make a plaster mould, now if i just moulded the resin pizza using plaster, i would never get them apart, so the solution is to pour melted plastilene clay into the silicone mould let it set up and then cast that using plaster, dig out the soft clay and hey presto a useable plaster mould for a cold foam rubber cast
here is the silicone mould filled with melted plastilene clay

Looks kinda like chocolate frosting (or icing for my fellow brits)
And here is the clay pizza a couple of hours later

Just needs cleaning up a bit, and a couple of the clay meatball heads replacing with fresh casts from the mould, then i will mould it in plaster and get my final rubber pizza out, then the fun can begin, the painting!.
It may seem a lot of work to get a rubber pizza out, but i feel it will be closer to the original that way, more to come!
