Made these three forms and even though they were slow drying, they all have cracks. So they are headed for the reclaim bucket and I am starting over. Sometimes that's what you got to do.
On the bright side, (cause you got to look for all things working together for good) I get to practise and correct the areas that lead to the cracking in the first place, which helps me to improve and grow. So to coin Simon Leach, "Keep practicing!"
