What were tin glazed pottery jars used for?

These vessels served primarily in apothecaries and dispensaries to store dry drugs, wet medicines, ointments, and syrups. Pharmacies relied on labelled jars to keep medicinal ingredients organised and protected from moisture. Over time, many of these utilitarian containers transitioned into decorative objects for domestic interiors. Lidded vases and ornamental urns were also produced purely for display in grand rooms.

How do I tell Dutch Delft from Italian Majolica?

Dutch Delft pieces often lean towards blue and white palettes influenced by Chinese porcelain, alongside distinct European floral and architectural designs. The glaze tends to be bright white with crisp cobalt painting. Italian Majolica frequently embraces rich polychrome palettes including yellow and manganese, often featuring dense historiated scenes or vibrant floral garlands upon heavier earthenware bodies.

Are lids usually original to these jars?

Many surviving jars lost their original covers over centuries of handling, cleaning, and daily dispensary use. Finding a piece retaining its matching period lid is a notable advantage for collectors. Nomenclature such as vase and cover or jar and lid in a description denotes a complete pairing, though marriage pieces with later replacement lids do occur.
