Lately I've been re-categorizing thousands of archaeological items at Wikimedia Commons and that inevitably made a lot of questions pop in my mind. Some of them are in an incipient stage:
When did stoneware become widespread (in Europe, Middle East and Asia)?
editHow expensive were the glass vessels comparing to ceramic vessels in Ancient Rome and in the Middle Ages?
editWhat prevented the glazed ceramic to become widespread and prevalent in the Claudian period and after?
edit(Vitreous enamel#History - Production is thought to have come to a peak in the Claudian period and persisted for some three hundred years, though archaeological evidence for this technique is limited to some forty vessels or vessel fragments). Started by: Fructibus (talk)
Because without glazing, the earthenware is not suitable for holding liquids, and they used Amphora for storing/transporting oil, which is a liquid. Started by: Fructibus (talk)
Is the Rio Grande Glaze Ware (Pre-Columbian) nonporous, like any glazed ceramic?
editWhat did the Pre-Columbian Americans use for storing liquids?
editTheir pottery was only non-glazed (and therefore porous) earthenware - (except Rio Grande Glaze Ware)? - Started by: Fructibus (talk)
How quickly is the water leaving an unglazed earthenware vessel anyways?
editWhy did the Ancient Romans throw Amphora at Monte Testaccio?
editFor being dented or because they wear out after a certain number of transports (like developing a certain unpleasant smell and taste that contaminates the oil if used again). Started by: Fructibus (talk)
