Creating a cast from an antique mould? Answered

I have a few antique tin moulds that make a variety of leaf shapes and wanted to frame them. I was thinking of making a cast from the mould to go along with the mould itself to demonstrate what the outcome would be from these molds. As the pieces are antiques (I inherited them from a Great Grandmother) I was not wanting to do any permanent damage to them such as having a resin stick to or dye the tin. 

Does anyone have a favourite over-the-counter product or a homemade resin idea? I've thought of polymer clay, liquid resin, and plaster. Not sure what would be the best to use. Each have their pros and cons. I was thinking it would be neat to use a homemade recipe as it would have a neat DIY/handmade/antique feel.

Any suggestions would be greatly appreciated :)

You could use store bought resin. If you go to the auto parts section of a big box store you will find silicone spray. Spray your mold generously and then pour in the resin, it won't stick. You will then be able to clean out the mold and have what you need. There are also some great homemade silicone that I've seen on instructables, I feel I added some to my favorites recently, they may be helpful.

Thank you for the input. That silicone spray is something I never thought of. I will consider it for the next batch as it was difficult to get the resin off the tin without cracking/chipping the resin.

I would imagine with out a spray it would be difficult. I've used the spray in all sorts of mold types (plastic, silicone, metal) and the resin pops right out, so my guess is you would be A-Okay :)
