Coolmorph is a thermoplastic that becomes malleable at the low temperature of 42 degrees centigrade, and then hardens at room temperature. All you need to get to coolmorph into a state where you can mould or sculpt it is a bowl of warm water.

To me this sounded like a potential prop making material. Now before we go on I should say that I am not the worlds greatest modeller but I did feel that this needed some investigation. So I applied for a review sample. What I got back was 25g of white plastic granules.

To test it – I need to make something so I decided on the tooth of an unknown carnivore. Something that could be made as a single solid piece and hopefully not beyond my skills. The tooth of an unknown carnivore appealed to me. This could be something useful in a number of genres and I saw steampunk, horror and fantasy applications for it.

So  filled up a bowl with hot water (from the hot tap – not a kettle) and poured in the Coolmorph. Almost instantly it started to group together and become slightly gelatinous. I let it take on some heat and moulded it into a ball. This was easy – it glooped together like an overweight jellyfish and soon I had rough ball of coolmorph.

The first of coolmorphs claims had come true. All I needed to start moulding this stuff was warm water.

Now I started to make the shape of tooth. It was fairly easy to pull apart and push and pull the coolmorph – although I was surprised at how dense it felt. I’m not sure what I was expecting but once I started working it felt much heavier than when dry.

As I continued to work the plastic it did feel harder to get into shape – so I put it back in the water from time to time in order to keep it soft and malleable. One thing I would recommend is a good supply of hot water if you’re going to do a lot of work with this plastic.

After a while I had the shape of a tooth. It was not smooth – it showed some granularity and had some rough edges but it did look like a tooth.

What I had built was a near 10cm long tooth that looked a little damaged and a little too white. I had my raw model. Right now it wasn’t suitable for use in a game. I would need to finish it off.

The next steps would be file / sand this to shape and to then paint it up.

I’ve left that part of the project for now – because I wanted to get this initial review out. However I may well have a go at completing this and when I do I will report it here for you.

My thoughts at the end of this experience are that coolmorph is an ideal material to build a wide range of props out of. It is not expensive (250g – 10 times the amount I used costs £8.75), and needs the minimal facilities to work with.

I would recommend that if you’re going to use to to either make moulds or to invest in modelling tools. Its easy to work – but good tools would be a real boon. I just used fingers and a palette knife and I think that shows.

That said – I think this ushers in a new age of bespoke props.

 Addendum – 23/06/2014

Since writing the review the owners of Coolmorph have been in touch with me suggesting that I did not have the water hot enough to get a good result. In the interest of fairness here is the point form CoolMorph. Please read this – it will help you use the product.

We own Coolmoph­™ and thank you for taking he time to do a review of the product.

Once thing I noticed though is that you probably didn’t use water quite warm enough. The pellets should completely melt before you start moulding.

You should experiment a bit with the plastic and you will find it very easy to mould with and will make much smoother better looking objects
