So what exactly is a Hydro-Bat Hump Mold? The Hydro-Bat Hump Mold is a bat that you attach to your wheel-head and use while throwing.
The mold attaches to the wheel with two rubber grommets embedded into the underside of the hydro-stone. After placing the hump mold on the wheel simply lay a slab on top of the hump mold. So think of it as throwing the backside of a form.
You will still have to throw a foot by gathering clay from the slab or by attaching a coil and compressing it to the back. Hydro-Bat Hump molds allow beginners and professionals to consistently make forms with ease.
We have a variety of forms and profiles within those forms. Just because these hump molds were designed to fit on the pottery wheel, doesn't mean you have to use them that way, they make great hand-building molds as well.

If you like throwing on plaster bats, you will love using a Hydro-Bat! Because the Hydro-Bat is made of Hydro-Stone instead of the standard pottery plaster, it’s full eight to ten times stronger than similar products. You will find the surface of our bats to be scratch resistant, while the bats’ water-absorbing properties fully eliminate the need to cut your pieces off of the bat with a wire.
Most of our Hydro-Bats have been designed to fit on standard wheel heads with bat pins placed ten inches apart. Our smallest Hydro-Bats, featuring diamaters of 6”, 8” and 10”, do require adapters to enable them to fit centered on your wheel head, but not to worry, we carry those too. All of our adapters are made of sturdy polyethylene plastic, and will become a studio staple for you along with your Hydro-Bats.
If you have a pottery wheel with no drilled bat pin holes, no problem! Many of our customers have used our Hydro-Bats with a bat gripper with great success.
