Thanks to daguin from this thread for the idea
1. First turn you oven to 450 degrees Fahrenheit.
2. Now gather as many marbles as you want to look cracked. You might want to start out with only five or six marbles just to make sure that this process works with your marbles.
3. Now put them into a small pan that is able to go into the oven. I put mine into a 8x8x2 inch pan.
4. Once the oven is ready put the pan with the marbles in it into the oven.
5. Turn the timer on your oven to 7 minutes.
6. While the marbles are baking find a small bowl and fill it with water.
7. Place ice cubes into the water. It doesn't matter how many ice cubes you put into the bowl just make sure that the water is really cold.
8. Note that once the timer has gone off take the HOT marbles out of the pan. Make sure to turn the oven off after you are done.Then immediately put them into the cold water.
9. Notice that the marbles will crack right before your eyes and should be cool in a matter of seconds.
10. Take them out of the bowl and dry them off.
LASE THEM!
