How do i get adhesive off a new ceramic dish?

i bought a new ceramic tagine (moroccan casserole) and it had a label stuck on it. i soaked it in water, and the label came off, but not the adhesive. i have scrubbed with a gentle abrasive sponge (i don’t want to use anything too strong, like steel wool) and it still won’t come off. is there a household product that will get it off?
