Printing inside a mug

[Wika]

Hello guys.

I wondering if any of you can help me.

I am looking for a 10 or 11 oz ceramic mugs suitable for printing inside like the inside bottom of the mug, inner rim and outside bottom. I know that the mugs needs to have a polymer coat inside and on the outside bottom to be able to be printing but is very difficult to find the ceramic one. I can use the unbreakable ones (plastics) but I am prefer the ceramics one.
I already contacted Signzworld, thetrasnsferpress, novacrome and none of them supply the mugs.

I hope someone can help me.

Thank you on advance

Short answer, you won't find a decent solution nor a way to actually apply heat with pressure to this area using sublimation. You will only be able to do this via decal and kiln firing.

Thank you for your answer.

Well...from my experience is no about the pressure (I used 3d vacuum oven) is because the areas I want to print isn't cover for polymer coat (I'm not sure if is because it can be toxic in contact with the liquid of the drink). The companies mentioned above confirm as well that is the reason, the mugs supplied by them doesn't have polymer coat on the inside or bottom of the mug. I am searching in most of the sublimation supplier without success. So, it look like I am only have to options:

Buy a transparent or white (or both) water based polymer to apply inside the mugs (I am not sure about that option).
Buy the unbreakable mugs (plastics) which are suitable for that purpose.

not sure that the polymer coating is in any way harmful or affected by hot liquids as the way many mugs are coated results in there being over spray of the polymer inside the mug.
