I noticed the problem about a year ago at my live seminar, Night Circus. There I decided to use Fimo Professional Cameo because the color and texture matched my ‘recipe’ clay blend that I have used for years.
In the past, the clays had more elasticity than they do now. Plasticizers had been reduced and other changes in the formula has led to this issue. Before I go on, let me say that overall I am still pleased with the END RESULT of the clays- the color, the texture and the strength is just wonderful. But the clay seems dry and cracks while you’re sculpting with it and that is incredibly frustrating.
I found by adding Cernit to the mix- this is the newest Cernit formula- to the Fimo Professional clay helps bring it back to the elasticity that it had before. About a 1/3 to 2/3 mix- so one part Cernit to 2 parts of the clay you’re using will help. You can refer to my clay blending tutorial to see how I blend clay. Check that out here: Clay Conditioning
By blending in the softer brand, (Cernit) it helps make the Fimo Professional softer and more pliable. Also, you will want to ONLY use the Cernit with the two dolls on the label, the one with the oval with three dolls on it is too soft and sticky- in my opinion.
In future posts I will share more ideas for working with the clays. I just wanted to post this now since the conversation has been ongoing. You’re not alone- don’t get frustrated and don’t give up. Working through the issues is completely worth it because in the end, the clay is so nice after baking.
