How do you make painted ceramics safe?
Things You’ll Need Make plain dinner plates colorful by hand painting them.

How do you make ceramic food safe?
The first is to squeeze some lemon juice on a glazed area of your project and then place the rest of the lemon on to the ware, leaving it overnight.

How do you paint already fired ceramics?
Use oil-based ceramic paints or a ceramic paint designed for use on fired ceramics.

What paint will stick to glazed ceramic?
