Hey guys!
I just thought I should update you - I have been experimenting with some other thermoplastic materials & techniques for my builds.
This time I used a combination of Worbla's finest art and Worbla's deco Art, white pellets with a melting temperature that is a little lower than the melting temmerature of Worbla's Finest Art. In case you are wondering Worbla's Finest Art has ~90°C, Worbla's Deco Art has ~65°C, so make sure you work on a heat-proof underground.
BONUS TIP: Baking paper can handle heat & is non-sticky so it works really well to roll or knead your Deco Art on but it will not keep the heat from your heat gun from your desk by itself.
BTW, there is a similar product called 'Friendly Plastic' that seems to be available in the US that can be bought in pellets, too. If you look around the internet, you'll find tuturials on how to use and even dye it (haven't tried that yet but it is worth investigating.
Why did I use it?
1) It's sticky enough to be combined with both the paper maché base or on top of the Worbla's finest art without the need for addditional products (in fact it is extremely sticky when you use dry heat to warm it, if you heat the pellets in water you have a more managable product).
2) You can use it to sculpt, and re-heat it to correct mistakes or add to it. The lower melting temperature means you can handle it with your fingers if you wet them (I still burned myself once, so be careful).
3) It is easier to create a smooth surface and I wanted a obvious texture difference between the hammered metal and the bone parts for this project. You can use wet fingers to smooth it or tools. Make sure whatever you use (fingers, tools) is wet so it doesn't stick to your project.
As always, I'll gladly answer any technical questions you might have, for now, let the progress images speak for themselves.
