transfer pizza onto stone without sticking After I have made my pizza and put the toppings onto it, I find that I am unable to transfer the pizza on to the pizza stone in the oven.

When I try to do it the pizza goes out of shape, gets folded, the toppings get messed up and sometimes it sticks or rips. I have tried putting lots of flour under the pizza before I add the toppings but it didn't really help.

I am having to make the pizza on a metal tray and then put the tray onto the stone. Put I think that doing this prevents my pizza base from crisping properly.

What am I doing wrong? Is there some technique I should use, or am making the dough to wet, or to thin or something?
I've worked as a pizza cook, so I can give you a hard-earned answer. Cornmeal, and plenty of it. If you aren't putting cornmeal (or flour, but cornmeal works better) on the peel before you put the pizza on it, start. If you are putting it on, use more. Then put the pizza on it and give it a shake and make sure the pizza is loose before you try to shove it in the oven. If it isn't, lift up the edge that is stuck and sprinkle more cornmeal under it, then try again. The pizza should be completely free-moving on the peel before you try to transfer it to the oven.
