do ceramic mugs keep coffee hot
Ceramic mugs are popular for their design and safety, but they don’t keep coffee hot as long as stainless steel or glass options. With a thermal conductivity of 3.8 W/mK, ceramic mugs lose heat faster than their counterparts. However, they excel in taste neutrality, ensuring that the coffee’s flavor remains pure without any metallic aftertaste. To enhance heat retention, preheating the mug or using a lid can help maintain temperature longer. Despite their limitations in heat retention, ceramic mugs remain a beloved choice for many due to their aesthetic appeal and ability to preserve the integrity of coffee flavors.
