If there is a pattern on the dinnerware does that mean not dishwasher safe?

It's not necessarily true that a pattern on dinnerware means it's not dishwasher safe.

Here's why:

* Many patterns are printed on dishwasher-safe glazes. The pattern itself doesn't usually affect the dishwasher's ability to clean the dish.

* The dishwasher's heat is what can affect dinnerware. Some patterns are printed with inks that are not heat-resistant and might fade or crack in the dishwasher.

* Check the manufacturer's instructions. Always look for the "dishwasher safe" symbol on the packaging or on the bottom of the plate itself.

Here are some things to consider:

* Metallic patterns: These are more likely to fade or change color in the dishwasher.

* Hand-painted patterns: These are often not dishwasher safe.

* Vintage or antique dishes: They might not be dishwasher safe, even if they have a simple pattern.

It's always best to err on the side of caution and check the manufacturer's instructions. This will help you keep your dinnerware looking its best for longer.
