I added some air vents to the mould, the next pour yielded much better figures,
- air bubbles in the silicon after setting, appear on the back of the casting
--> put figures in plasticene base and create first half of mould on top - the bubbles rise up !
- lack of detail in some places on the figures
--> need to improve the edge detail on aspects of the figure masters
--> brush some silicon onto the figures before pouring
- air vents to be added at mould making time if possible
- pouring reservoir shapes to be improved
Made some basic mistakes, but that's part of the learning process. I have sold some stuff on Ebay recently, so will buy another silicon mould kit; we'll see how things go from there.
