Polymer clay is the most amazing, versatile material! It can be made into anything you want, in any finish you can imagine! You want it to look like opal? jade? metal? glass? the list goes on forever! Google "polymer clay tutorial" and add whatever you want to emulate and chances are someone can tell you how! The "pearl" colors have tiny bits of mica in them, and there are techniques to obtain a cool effect known as mica shift that makes it look as if a pattern has depth, and yet it is perfectly level and smooth! The stuff is addictive, I must have a gazillion pounds of it! LOL Oh, by the way, once it is baked correctly according to pkg directions, it is very resilient stuff and won't break easily. The temperature and length of time baked are critical to it's durability... an oven thermometer is a great tool for that as every appliance is different and a dew degrees can literally make it or break it. Great job for a 1st effort, I bet you will be finding lots of uses for it! I'm a jewelry designer and I use it all the time! It's a life saver when you are trying to tie unmatched elements together, or have an idea for something that doesn't even exist...ler me shaddup, I can go on forever about it! Enjoy!
