This is a very helpful guide in the black art of casting. Although this is directly aimed at resin casting the principles are the same if you wish to cast white metal or tin. You can still buy high temp silicon for moulds. (I used to cast fishing lures with it).

I took the liberty of merging all the separate threads into one post, otherwise they will get mixed up and lost.
Thank you for sharing this

Hi monica,
I am not sure what you want to do with the green stuff.
Is this the Green Stuff filler you are going to use?
To make a solid mould, then your choice should be Plaster of Paris, but then you come to the problem of removing the item from the mold/mould, and Green Stuff once hard can become brittle, the inner part may not harden due to lack of air.
If you let me know what you are trying to cast, then I can point you in the right direction, and spend time helping you.
Please get back to me.
Cheers, MikeC.

I have used Oyumaru Reusable Modelling Compound , a weird material that you heat up in hot water and then can use as a pliable material you can embed an object in. when it cools remove object and you have a nice small mold for smaller items , or melt a few blocks together to get a bigger mold area.

Gary,
Great idea for push moulding.

Resurrecting an old thread but it has fantastic information on it.

I have a question though. I would love to give casting a go as i have an idea to make something that would save me a load of time scratch building. But i would like to know how i can ensure little plugs can be filled with the resin without having stubs to draw the resin through? The attached picture is for reference only and not the item i want to cast. I was just wondering how they did it without air bubbles/voids

Excellent Mike

I have the kit and need to copy three different parts, two of them a few times. Will have a good read
