Why is lead used in ceramic glazes?
The glaze – which may contain lead to facilitate the melting of glaze particles – fuses to the pottery when it is fired in a kiln, a special oven used to bake clay.Because the lead may not fuse into the non-lead glaze, it may contaminate food when the pottery is used with food.

Are ceramic mugs safe to drink from?
If ceramics are baked for long enough at hot enough temperatures, they may still be safe, but if not, the lead can leach into food and cause lead poisoning. Acidic food or drink is especially likely to cause lead to leach out of ceramics, unfortunately for coffee drinkers with favorite earthenware mugs.
What is the best material for coffee mugs?

Are all ceramic mugs microwave safe?
From my observation, most manufactured glassware and mugs are microwave safe so long as they do not have metal gilding. A lot of companies still apply "microwave safe" labels to a lot of products, so you can still look on the bottom to be sure. On the other hand, hand made pottery tends to be less safe for microwaving.
