The process of creating ceramic coffee mugs involves several stages, each contributing to the final product's quality and durability. Initially, raw materials are ground into clay powder and mixed with other elements such as quartz and feldspar.
Screen printing can be used to print a design or logo.
Glazing
Mugs receive color and glaze. It's painted to ensure quality coating. After the mug is painted, it is set aside to dry.
Handle Application
Handles are dipped into a mixture of clay and water called Slip. This acts as an adhesive binding the handle to the mug.
Milling
Raw material is fed into a grinder and crushed into clay powder. The powder is added into a mixer with quartz, feldspar, and water. It's fed into molding tubes and cast into long clay mugs
Firing in a Kiln
The mugs go into the oven or kiln. Rows of mugs are put onto a conveyor belt and into a standard temperature of 2,200º F.
Detailing
Excess clay or rough edges are removed. Dust or debris are rinsed, giving the mug a smooth finish.
Molding
Clay logs are cut into portions, placed into a single use mold, and formed into the shape of a mug. Once the mold is dry, the mug is removed.
