It's a job for real vikings! To make a helmet, you’ll need:
You will receive this helmet after gluing.
After you finish the paper frame, you can move on to resin molding. Be sure to put gloves on for this operation. Mix the resin in plastic cups then take aluminum foil and use it as a base for helmet’s coloring: resin doesn’t stick to it.
After the resin dries you can turn the helmet over and start its interior decoration. You will require a glass mat (fiberglass) to strengthen the inner side of the helmet. You have to start with spraying glue and putting a glass mat on it. Then we have to cover it with resin from the plastic cups. The resin will react to glass mat and so the helmet will remain hot for some time. We have to leave the helmet for a few hours.
Unfortunately, you won’t be able to cover the horns from their inner side, so we have to cover their outer side.
Now we’ve given rigid frame to the helmet and can move on to more artistic part of the process – plastering and painting.
We have to mix water with PVA glue and plaster in 1:1:2 ratio to create the mass for the plastering. We can put it in few layers to achieve the desirable thickness, but we have to put each new layer only after the previous dries completely.
When the plaster molding is finished, we can add dents and other signs of damage to the helmet, making it look like the one that has already been in a fight.
After the plaster hardens completely we can move on to the last and most enjoyable part of the process – painting. To do so, mix yellow and brown paint and color horns with it to make them look natural. You can use darker paint in some places (grooves) to make them look dirty and used for a long time.
Now we can move to the “metal part”. We paint it all in black color.
Then we take silverfish paint and put it on the “metal part” in thin layer not evenly: we have to color different parts of a helmet to make it look like it’s made of steel.
After this everything depends on your imagination only: you can come up with your own ways to modernize the helmet.
