Does food colouring stain china bowls?

Here's a breakdown:

* Water-based food coloring: This type is generally less likely to stain china bowls. However, it's still possible for the color to seep into the porous surface of some china, especially if left to sit for a long time.

* Oil-based food coloring: This type is more likely to stain china bowls due to the oils in the coloring. The oils can penetrate the glaze and leave behind a noticeable stain.

* Natural food coloring: Some natural food colorings, like turmeric or beetroot juice, can also stain china bowls, especially if they are left to sit for a long time.

* Glazed vs. unglazed china: Glazed china has a protective coating that makes it less likely to stain than unglazed china. Unglazed china is more porous and can absorb color more easily.

Tips to prevent staining:

* Use a small amount of food coloring: Less coloring means less chance of staining.

* Wash bowls immediately after use: Don't let the food coloring sit in the bowl for a long time.

* Pre-soak bowls in cold water: This helps to loosen the color and make it easier to wash away.

* Use a mild detergent: Avoid harsh detergents that can damage the glaze.

* Don't use bleach: Bleach can damage the china and make the stains worse.

* Try soaking the bowl in vinegar: Vinegar can help to lift some food coloring stains.

Overall: While it's possible for food coloring to stain china bowls, it's not always a guarantee. The best way to prevent staining is to use a small amount of coloring, wash the bowls promptly, and avoid using harsh detergents.
