I’ve had some Siligum moulding paste and EasyCast casting resin for a while now, and I’ve always put off using it in case I messed it up! Finally I decided I’d try it, and I wanted to share my results!
Siligum comes in two pots – one blue, one white.
Take two lumps from each pot that are the same size. Mix them by kneading them, and rolling them between your hands for around a minute.
When they’re a solid colour, it’s ready to use, but beware, it sets in five minutes! Press the item you want to make a cast of into the paste. This is a copper blank of a cog, but I also tried taking an impression of a spider ring which really didn’t work.
Here it is minus the cog blank! Next job was to mix the resin, which I didn’t take photos of as it was a tad messy. Take equal parts resin and hardener and mix with a wooden stirrer. I used a measuring cup and a cocktail stick. After two minutes of thorough mixing, pour into a second container and mix using a fresh stick. After a minute, you can add any colourants – I used black mica powder. I added it to the mould by adding droplets from the cocktail stick until the mould was full.
Leave the resin to cure for 72 hours – not good if you’re impatient like me! Some resins and moulding pastes need a release agent to get the cast object free but I found using my products that this wasn’t the case. I simply popped the resin object out of the mould.
Here it is, closer up. I bought all of my supplies from Metal Clay – Siligum Moulding Compound; EasyCast Clear Casting Resin; small mixing cups; a 19mm cog blank; and the colourant was Pearl-Ex powder in carbon black.
Have you ever used resin or moulding paste?
