Hand-painted mugs, mugs with metallic inlays, and ceramic mugs with certain types of glazes can be damaged by the high heat and harsh detergents used in dishwashers. Additionally, mugs made from certain materials like thin porcelain or bone china can crack or chip. To preserve the longevity and appearance of your mugs, it's best to check the manufacturer's care instructions or opt to hand wash them.
