Crackled Cane Slices! Aaakkk! That Wasn’t Supposed to Happen!
The problem with having too much of any one polymer clay cane, is that the cane can get old and unpliable if it sits around too long. It is one of the reasons I don’t often make enormous polymer clay canes.
What happens is that the plasticizers either settle or leach out of the clay. And then the cane becomes brittle and cracked, making it impossible to work with as is.
Just look at the picture above. The bird cane slice that was added to this polymer clay ‘fabric’ sheet was too brittle. And although it sliced up OK, when it was rolled out thinner, it crackled all up.
Don’t despair though. These old canes cane be revived. Here’s an article written awhile back that most of you will not have read before. It’s all about how you can make your old canes, soft and pliable again… Reviving Hardened Fimo Canes
One more tip. If you’ve had a cane sitting around for awhile and you’re not sure if it’s old or not, take a fairly thin slice and slowly bend it in half until the sides touch. If it bends without cracking it’s OK to use. If not, it could use a little reviving!
