The video clip is of my last attempt to make a resin heart-shaped bottle.
Casting a Resin Heart: The Resin Phase from pagesinclair on Vimeo.
I have attempted this phase four times in all, and none of them worked out the way they needed to. I had the same issue with every resin casting I did. The surface exposed to the air would dry perfectly and was as smooth and glossy as polished glass, and then I would release the cast from the mould and the surfaces that were touching the mould were sticky and not set properly. It was only the surface that came into contact with the mould that wasn’t set, the rest of the resin seemed solid. It’s very odd, but only because I haven’t contacted the suppliers of the products to see if they know the reason I am having this issue every time I cast, given that I have varied what I have done to the inside surface of the mould. So I can only surmise that it is either the rubber mould itself reacting with the resin, or the total occlusion of air between mould and resin that is the issue. The other problem had been a small air bubble trapped between the cast and the mould where the neck of the bottle was. I think creating a mould where the bottle neck was down at the bottom of the mould and the opening for pouring would be the base of the bottle, (so upside down (as it is at the end of video clip)), would have solved the trapped air issue.
