Hiya Soup - what a bargain, very jealous over here
Oh drat, I forget the actual name of the stuff it sounds like it could be but its basically acrylic/plastic beads that you melt in the oven - you usually get bags of colours in kits that have a metal "stained glass" frame to fill & melt into a fake stained glass.
I used to use this stuff with fimo to make stained glass jewellery & coloured sugar would describe it well - could this be it ??
Could I ask you do you use your normal oven to bake the Fimo? If so, for how long do you need to air it before you can use it for cooking again or do you do something else before using it for cooking again? Thanks.
