Now, the lost wax method of producing, say, jewellery was know as far back as Egyptian times but as far as I know it is not very often used with resin.
I have spent quite some time on a previous blog complaining about the shrinkage rates of various waxes and that has probably been a bit boring as most readers will not have any idea why I am so interested.
So…a set of photos to explain how I made the canopy of my new birch…. the ‘why?’ is simple… I wanted to cast the piece as one piece of resin rather than have a ‘join’ which is difficult to disguise.
The first step was to cast a sort of ‘former’ from a mould that could be reproduced each time as the same size. This is where the different waxes produced different results…. I decided to live with the slight variations and do remedial work after casting…
I used epoxy putty to make the rings which stuck nicely to the wax..
..and filled inbetween the rings where bubbles would otherwise develop during casting… I used a wax to do this but I could have chosen any other material
I then coated it all in silicone rubber. To be honest I think I will have to remake this part so that all the dents are filled as the support mould (not shown) has been a weakness in this mould. Having no dents would make life easier.
Cast with crystal resin …
Melt out the wax and all it needs now is a good clean and some painting… oh and a bit of remedial. I may recast it once I’ve photographed it if it gets accepted for the show. Hiding flaws is a part of being an artist in any medium I think, you just have to get good at it.
My airing cupboard is full of resin bits and pieces drying as I am trying to finish everything at once and end up shooting myself in the foot as I have nothing to do (nothing can be touched til it’s dry) and I actually had a (quite welcome) night off for once, doing nothing. My lobby is also full of very smelly resin stuff as it’s nice and airy and I don’t want it in the house til it’s set hard.
I have finished casting the base, almost and will post photos when I have a finished one to accompany the process. It has taken masses of resin and I have an almost constant stream of Amazon products (slight exaggeration) delivered to my door … I’ll have to try a bulk purchase next time…. or make something smaller.
…anyway, have a good weekend, I’m gonna be getting busier and busier as the week progresses… excited but nervous.
