Hi Sally - thanks for your reply.
I've got some 2 part epoxy resin now so I'll give that a go.
The alginate I use is from www.tiranti.co.uk. For the children that are too young to undertand instructions I've tried to get the setting time down to as short a time as possible. I use the Tiranti Normal Set aliginate at a ratio of 3:1 (water:alginate by weight) with warm-ish water which gives me about 30 - 60 seconds to work with. This seems to be working fine and I've been getting good results with my 6 month old son. I think the older the children and the more strength they have in their fingers means its more down to luck than anything else! My nephew at 18 months old was fascinated by the blue goo and we think he spent most of the setting time opening and closing his hand. By the time it had set too much for his fingers to move the damage was already done and the mould was ruined.
The biggest problem I have with casting babies hands is making sure I dont lose tips of curled up fingers through trapped air. When pouring into the mould I try to ensure I hold it at a suitable angle but sometimes still lose the odd finger tip. Any ideas?
Did you have a helper when you took the mould of your belly? I cant imagine it being too easy doing it on your own!
