This week I removed the first casts from the moulds. They are perfect in terms of shape and their lack of bubbles.
Unfortunately the resin has yellowed which could be something to do with the thickness of the cast, the batch of resin, the speed of the catalyst, or all of the above. I am going to call the suppliers in the morning to discuss.
Next: I am meeting with another GSS artist tomorrow to discuss a metalwork lesson in order to make a start on the support. The first will be a flat structure held at a remove for the wall, almost like a bed/plinth.
