Hi,
Having thought I was succeeding with the pigmented casting I now have a problem.
The item I am trying to replicate is a toy battery cover. This is quite thin and black and not only do the casting sometimes seem to be not quite an overall colour there are sometimes small pinprick sized bubbles of uncured resin appearing after the casting has cured. I made a two piece mould but wonder if it is not rigid enough - any suggerstions.
Are there any members out there in the UK who can assist me
Regards
Alan
