Step 2: How to Make an Impression

I covered the back of several leaves I collected with a generous coating of mineral oil.

The back veins are deeper on the leaves than the front and are perfect for casting.

Roll out a piece of clay that is larger than your object for casting.  Here I rolled the playdough onto baking paper and pressed it flat with a piece of plastic wrap.

I then pressed the leaves into the sticky playdough.
Hi. Can i use it for 3d casting of my hand?
You might like to try and experiment, cool idea though.
how many time can you reuse it before damaging the mold?
6 years later my mold is super strong and super strong after sitting on the window sill.I'd wait for it to dry thoroughly. Speed it up in a glass bowl in the sun might help : )
also, any chance for making 2 part mold?
food grade silicone is perfectly safe to handle
<p>yea and makes a gr8 release agent for any mould in that temperature range</p>
hi, it is a good idea but if you use cold porcelain <br>dough or salt dough it will not take that much time<br>to dry <br>the cp will take about a day <br>and the salt one but it in the oven<br>the thinner the leaf the faster it drys <br>
Thanks for that! I'm still experimenting with CPC, and its a lot harder for me than it looks. You instructables are quite helpful too!
use han solo in carbonite toy instead of leaves and use sticky playdough for mould and once dry poor in melted chocolate
Flour/salt doughs tend to be porous (and leach salt) so the chocolate would stick (and licking it off the mold would taste nasty). The cold porcelain might work better, a vacuum former could create the same molds that you can buy at the candy store.
thanks for your comment, true the salt on chocolate might taste bit funny, but I'm not sure pva is safe to ingest - particular some glues made o'seas might include formelhyde not safe for those expecting. otherwise all the ingredients above are pretty safe with chocolate
The trick would be pulling the chocolate off the mold.
interesting concept, all the ingredients are safe, except too much of the ca hydrate, may cause stroke
