Artist acrylics are not a replacement for ceramic glazes and should not be fired in a kiln. Melting acrylics is unhealthy. Acrylics have poor adhesion to glazed ceramics and you could likely scratch it off with your fingernail. This is the reason we do not recommend painting on glazed ceramics including tiles; the paint will not make a permanent bond and would remain vulnerable to scratching. Adding GAC into the paint or applied first and then paint applied on top could create better, but not perfect adhesion to glazed ceramics.
What we discovered was that all three of the acrylic paint lines generally had good adhesion to the unglazed pottery. We saw a small bit of a failure with the Fluid Acrylics and Heavy Body where the paint was applied thicker, so our best recommendation would be to keep the paint thin or use High Flow Acrylics, which soaked into the pores and became more incorporated into the piece.
In fact, the clay was so absorbent there was no film built up on to the surface from the High Flow to even cut for the adhesion test! Of the mediums tested, the only one that had poor adhesion was the GAC , so if you wanted to create a translucent glaze-like finish with acrylics, we would recommend High Flow Medium, as this is our thinnest medium. The GAC , which is our hardest paint film, mixed into the paint could also be used.
These will give a tinted glaze to the piece. You could stop at this point if you were just creating a decorative piece of art. If you would like to use it to hold water or a plant, we would recommend applying a functional and highly durable topcoat inside and outside the pot. We tested a couple of products on the market to see if it would become waterproof and what we found was the two part epoxy held up the best.
We suspected that if a bisque fired vessel was only painted with acrylics, not topcoated, and filled with water, that the acrylics would blanche and swell and eventually fail because they are porous on a microscopic level.
Our test showed otherwise. After a week filled with water in a porcelain pot painted inside and out with Fluid Acrylics, the paint held and saw no issues.
The water caused this layer to quickly blanch and the bowl dried with a white coating. We think if constantly filled with water, this coating could potentially blister and peel in time. Another option for the painted pot to hold a houseplant, could be to line the pot with some plastic sheeting. We tested GAC because it can improve adhesion to non-porous surfaces and GAC because it can improve adhesion to chalky surfaces.
All three of the paint lines failed the adhesion tests. The GAC and also failed. The GAC on its own had better adhesion, but we saw some failure with the acrylic mixed in or on top where it was thicker in the high points of the brush strokes. Acrylics are soft and flexible, so if you would like the paint to be harder, you could mix GAC into the paint to make it harder.
While we did see some success of the tests with the High Flow Medium and GAC , we would consider it adequate adhesion and not a permanent bond and it may not hold up over time.
Painting bisque fired ceramics can be a good alternative if traditional glaze firing is not an option or you desire a more painterly finish, but we must stress that paint is not as durable as ceramic glazing and should only be used for decorative purposes as a sculptural art piece.
A benefit to painting instead of glazing is the control that can be had of line, mark or image. There is always an element of surprise when a piece is removed from the kiln after a glaze firing. Due to the nature of the ceramic glaze becoming liquid in the high temperature of a kiln, most glazes tend to move, flow, run, or change color and details and hard edges can be difficult to achieve.

If you 're refinishing the look of your home or bathroom, you can paint porcelain tiles with acrylic latex paint or two-part tile epoxy that mimics the look and feel of porcelain.
