I’ve been working on a tentacle for my Lab 558 video. This is for the climax of the video, wherein the lab is breached and a cloud of pestilence and tentacles escapes and destroys the world 😉
I’ve previously posted the mechanism, this is a silicon skin that will cover it. Here’re some pics of the initial chavant sculpt and the cast silicon skin:
As it’s a very long and thin shape I decided to make a mold of this inside some guttering pipe that I cut in half. I then poured in plaster. I like making plaster molds of chavant – as the clay is oil based it doesn’t stick to the plaster, so it makes separating the mold from the sculpture very easy. Similarly, the silicon I’m using (Tinsil Gel 10 in this case) doesn’t stick to the plaster, although a layer of vaseline as a release agent is helpful.
I’m painting the silicon using a mixture of translucent silicon bathroom sealant (Homebase own brand if you’re interested 😉 ), white spirit and oil paints. It’s not quite finished yet, here’re some pics so far though:
It should look quite nice once it’s all covered in slime 😉 I made this using a chemical called Borax which is something used in laundry detergent and PVA glue – there are plenty of recipes on Youtube so just search for ‘borax slime’ if you want to know how to make this. Some of the ingredients in the recipe vids are US specific however. As I’m in the UK I ordered the Borax from ebay (I got 1kg which is WAY too much!) and used clear PVA glue (because I wanted clear slime) – the make I used was Pritt craft glue (you can get it in WH Smiths).
