Instamorph is a low temerature thermoset plastic, which melts at only 60°C / 140°F. This makes it particularly suitable for moulding with your hands, even to the extent that you can mould a mask to your own face before the plastic sets!
Step 1: Melt Your Instamorph
Materials you will need...
- A packet of Instamorph
- Silver spray paint
Tools you will need...
- Bowl to contain hot water
- Heat gun
- Tools such as a small drill, a dremel, etc
Melt the Instamorph
You have to dip the Instamorph pellets in a bowl full of hot water at 60°C / 140°F. Wait until the pellets turn transparent and stick together. Remove it from the bowl carefully and remove any extra water hidden in the block of melted Instamorph.
Step 2: Mould the Gross Shape of Your Mask
Instamorph is mouldable for a short time so you have to work quickly. I worked the material until it was too hard to shape, dipped the Instamorph again in hot water each time adding hot water to the bowl to keep it at the required 60°C / 140°F.
A heat gun can be a very useful tool to shape smaller details but be careful not to heat the Instamorph too much otherwise it will start to melt and bubble, it will be boiling hot and virtually impossible to manipulate by hand.
To get the correct shape, I held the flat piece of Instamorph to my face when it was cooling and beginning to go white, so that it wasn't too hot to hold near my skin.
I used my fingers as it was cooling to get the gross shape of the mask, including eye holes, a ridge for the nose, and I pinched along the edges to make an interesting shape.
Step 3: Add Fine Details Once the Plastic Is Set
Once it is completely cooled, you can use any tools to work the shape further. You can cut it, polish or drill it with no problem ... It is a surprisingly strong material.
I used a drill to make holes for the fastening and a dremel to finish the edges.
Step 4: Paint Your Mask
After the sculpting was completed I used spray paint and dry paint brushing to create a fake quicksilver metal effect.
