Hello! I purchased the delft clay casting kit a couple of weeks ago and have had a few goes with it since. For the first few attempts I accepted that they wouldn't be perfect and this was fine but 2 weeks on and I still haven't had a single successful cast. So far the two main problems I have come up against have been that the mold will not properly fill up before the silver hardens resulting in an incomplete casting and even on the incomplete casting there are small cavities which I can only assume were air bubbles. Most of my attempts so far have been at casting a guitar pick (about 25x30x2mm) and only once has the mold filled up completely. Every other time the silver seems to harden far too quickly. I have been creating plenty of air vents and making the pouring hole around 5-6mm every time.
Does anyone have any suggestions/tips for me? I've watched several videos and feel like I've had enough attempts to at least be getting full casts by now but I'm getting slightly jaded with it now as the time it takes to prepare the mold seems wasted if it's not going to work. Does the mold need to be heated perhaps to keep the silver flowing a little longer and if so how is this done? Thanks for reading and for any advice you might have!
