The Polymer Clay Test To The Latest, Pardo Art Clay, Fimo Classic, Premo Sculpey And Cernit Test Two Baking At 140ºC/150ºC For 30 Minutes, Switching The Oven Temperature Off And Allow The Test To Stay In The Oven For An Hour (Aways preheat oven for 15 minutes) Test Two Pardo Art Clay Pardo Art Clay From Fresh Pack Conditioning starts straight from the clay pack It is messy to condition Pardo Art Clay Condition above 5 minutes still have difficulty in blending the clay Continuing the process still doesn't blend the clay completely Finger kneading is require to condition Pardo Art Clay, noticed the clay stains on my palm, both test 1 & 2 shows the same problem. Fimo Classic Fimo Classic Clay from a new pack Test starts with conditioning above piece of Fimo Classic Although the Fimo Classic is also crumpy, it is easier to condition Conditioning Fimo take less than 5 minutes, gives a better blending The blended Fimo clay create lesser stains than Pardo Clay Premo Sculpey Premo Sculpey from a new pack Premo clay piece feels softer from the pack Less than a minute and it blends easily Cernit Cernit clay from a new pack The Cernit piece is also soft to handle Rolling the clay will soften it quickly, if the hands is too warm, will make the clay soft and difficult to shape Test tile before baking
Test tile after baking no color changes Numerous tests were conduct to obtain the different results

Conclusion

I have selected the four different brands of clay which were considered to be better in quality, but both tests yeild different results using different baking method. Testing all the clays for flexiblity, adhesion and strength, depends on conditioning and baking the clay at the right temperature. Test two produced a better results, with the recommended temperature, but you will have to leave the clay project in the oven to absorb the heat for an hour. I've found that improper conditioning or kneading the polymer clay create inconsistent results, such as bad adhesion and strength. You can also get better result by baking the clay for 45 minutes instead of 30 minutes. Even with the recommended baking temperature of the new Fimo clay at 110º C, it should be bake at the normal temperature of 130ºC or my recommended baking temperature. For Pardo clay that is difficult to blend, add some baby oil that will take a shorter time to condition the polymer clay (test conducted strictly through kneading without using the baby oil).
