This is an extension of Polymer Clay Basics – Part I.
First & Second Test
I initially did a few rough experiments myself though with different substances. I only thought of a few things I had on hand (not baby oil), then I redid part of the test with the baby oil but I didn’t bake it exactly the same (the first test you see in the pictures was slightly overcooked). So it was a bit of a mess but it told me that in a pinch you could use just about anything. At normal cooking temperatures there was very little difference in coloration. There were some differences in flexibility but Fimo is so flexible no piece broke from the bending.
