Re-meltable latex material for making permanent negative moulds. Can be easily melted in a 'bain-marie' and used over and over again.
Not suitable for the copying of wax originals.
The blue Gelflex is slightly harder than the white Gelflex.
This is a great equivalent to alginate or silicone but please note it is not suitable for making moulds of body parts as it will be extremely hot in it's liquid state.
We have not tried this at Warm Glass, but there are forums online where people discuss successfully casting in resin using blue gelflex as a mould material. In the cases I saw no release agent was used. I'm not sure if the resin process produces heat, but bear in mind that gelflex melts at around 150C.
