I recently purchased some 6m wire from the dollar store for a sculpting project. However, the wire seems to have a sheathing on the outside. (See pic)
Is this stuff safe for baking in the oven with my sculpt?

According to this post, the black and red coloured wires are insulated with plastic:
2 coils at 33 feet wire red plastic insulation
2 coils at 33 feet wire black plastic insulation
Unless you find packages with the regular 'silver' coloured wire - which according to a review here might actually be hard - I suggest using different wires.
