[QUOTE="TheLabGuy, post: 21140, member: 126"] These are my two guesses........only because I've done it a few times. 1. You are not following your specific gravity (density) when you cast. You should be weighing your sprued wax ups, then times that by the density and that is your exact weight you should be using, and only that much. 2. Now if you still notice you get them, it's usually because it's a big crown, larger crowns you should use some chill vents. Now, if you go back to some older threads, you will see that I posted some pictures and we all had a long conversation about this previously.....i'll try to find the thread. [/QUOTE]
