What can I put in ceramic cups to stain them?
<|assistant|>
You can put tea, coffee, or acid based liquids in ceramic cups to stain them. The liquid should remain in the cup for a few hours or overnight to allow the stain to penetrate the material. Some acids, such as lemon juice and vinegar, can also be applied directly to the cup prior to staining. This is useful for creating a unique, one of a kind design.
