How to Paint Pottery Before Firing
To paint pottery before firing, you have several options for paints.
AMACO’s semi-moist underglaze pans are recommended for watercolor-like effects, while liquid underglazes allow for acrylic-like effects and heavier application.
Working in layers with liquid underglazes is best, as they are not at full strength until three layers are applied.
Keep in mind that dark colors may bleed through overlying layers.
For unglazed pottery, acrylic paint is recommended as the best option, while enamel paint is durable and resistant to high temperatures for glazed pottery.
To prepare the surface, sanding and priming the ceramic is important, followed by cleaning and drying to remove dust and dirt.
When painting, use a small amount of paint on a palette to conserve.
For shading, dip the brush in water and lightly dab on a paper towel for a smoother texture.
Allow each coat of paint to dry before adding more.
After painting, air dry the piece if it is glazed, or bake it in an oven or kiln to increase durability if it is unglazed.
Finally, protect the design with an acrylic sealant for unglazed pottery.
