Ceramic soap dispenser leaks

This is not my biggest problem; it's just annoying.
My toothbrush holder, mug, and soap dispenser are a pattern I really like.
However, the soap dispenser leaks, how I don't know. No breaks, just slow leakage from ??? I retired it for a while, then decided I WOULD solve this problem.
I thought of pouring some kind of glue or? into the dispenser and swishing it around, hoping it would coat all around inside at the base.
Am I just a cockeyed optimist, or is this doable, and if so, what should I use?
TIA

Sorry - I was unclear. The set is MADE of ceramic -- china, porcelain, whatevah. Fill it with liquid soap --Dr. Bronner's , BTW, which doesn't contain the chemicals in most soaps -- propylene glycol, etc.\\

Only things I can think of is a hairline crack or porosity of the ceramic itself allowing liquid to weep.
You can try wrapping it in a paper town and watching for it to absorb the liquid and show a spot.
In any case, it first you'd have to drain and rinse well. That will be a PITA, but you have to get the soap out for anything to cling. Then you could try some sort of thin epoxy and swirl it around, but most epoxy mixes are too thick to work well. Same with polyester resin. My guess is that the smart people here will think of a good liquid that would leave a coating and be thin enough to easily swish around and drain.

I have found that with temperature changes, and a tightly sealed pump assembly, that as the unit heats up, a little soap is forced out around the top and oozes onto everything. Try filling the tank close to the top, leaving the top pump asssembly off, and see if there is still leakage. if there is, then the tank is cracked, if not, then put the pump assembly on loosely so any expansion due to temperature changes can force air out around the top and not force sooap out thru the pump. Let us know what happens!!!

Thanks to other inquiring minds for ingenious comments.
I should point out that the leakage occurs AT THE BASE, not the top, so I doubt if it's what hr (Bob) suggests, but will keep in mind.
Aha! moment! Ed suggested wrap in paper towel and look for spot. Might indeed be the way to isolate a crack or other aperture not discernable to the nekkid eye.
Will report back when results available.

After trying the paper towell idea and finding the leak source, maybe this will work:
Completely rinse and clean the inside with hot water and allow to dry completely. Then use Super Glue -- the liquid kind, not the gel kind -- on the inside and swirl it around as much as possible. I have used Super Glue on hairline-cracked toilet bowls and even toilet tanks and have had it work. It seems to get drawn into the crack by capillary action and then dries and seals the cracks. Or, maybe some type of clear and thinned polyurethane sealer on the inside will do the same thing.

That's exactly the approach I was kicking around. Will try the polyurethane first since I have some on hand. If no luck will pick up some Super Glue; I need some anyway.
Will post results next week.

I got a reply on my email, not this NG, using this Subject. I could not read because in Arabic. Linked to a video, in Arabic, spoken by a pleasant male voice. Somehow doubt the relevance to soap dispenser. <g>
