There is no good reason that we are still using ceramic over enamelled steel or injection molded resins. Other than some hoity-toity friends and family will call us trashy.
Metal is fine for cooking utensils but when used for plates and dishes it helps hot foods to cool too quickly.
Enamelled table-ware is made, but that too is fragile in that the enamel is a brittle ceramic, easily chipped.
And if you've had a hot drink from an enamel mug, you'll know why such mugs have been nick-named "lip burners".
