I have heard of people firing the same piece up to 10 different times. Other times it is a deliberate plan. That many re-fires can start to weaken the clay, depending on the temperatures and the clay bodies used.
It gets a little more complicated with reduction firings, including Raku. If re-fired in an electric kiln, the black will burn out and you will get the clay color where it is bare.
Reduction and Raku glazes may or may not look good re-fired in oxidation, but they will probably look different. I took a workshop with Kevin Myers where we did Raku, followed by china painting on certain areas. We focused mainly on painting within the lines of crackle that had been created by the first firing.

A cone 5 fired bowl leaves a water mark on the table after it comes out of the dishwasher. The bottom of the pot feels dry and the glaze is a Miller glaze I've been using for years without any issues. The clay body is also Miller, Is this something that you recently made, or a piece you made a while ago? This may be way off base and too unprofessionial. I don't know if that is an option or not depends on what you are wanting. Good luck Kabe. Duncan French Dimensions need to be fired to at least cone So the low fire would not be sufficient.
If you want a low fire alternative without going the oven route which I personally don't like , you could use china paints or fired gold. They aren't raised but will get the job done.

Best method I prefer to use is warming it up in microwave however size is a factor as it has to be small enough to fit. Glaze crazing or glaze crackle is a network of lines or cracks in the fired glazed surface. It happens when a glaze is under tension. Generally, crazing is considered a glaze defect because the vessel can be significantly weaker than an uncrazed pot.
Craze lines can also harbor bacteria or germs. Fluid melt glazes, or those having high surface tension at melt stage, can blister on firing if applied too thick. Glazes having sufficient clay to produce excessive shrinkage on drying will crack and crawl during firing if applied too thick. Fluid melt glazes will run off ware if applied too thick. Can you Refire Raku? Typically, three coats are applied. Each dries slowly, hardening as it does so the glazes contain binders.
