Can I use these pots for live plants?

Historical pots, particularly early tin-glazed earthenwares, remain porous and can suffer structural damage from damp soil. Moisture causes soluble salts within the clay body to expand, leading to glaze flaking. Utilise a modern plastic liner inside the vessel if housing live greenery. Ensure adequate drainage protection to prevent standing water from contacting the interior base.

What is the difference between delftware and stoneware?

Delftware consists of a softer earthenware body covered in an opaque tin-lead glaze. This creates a smooth white surface ideal for painted cobalt decoration but leaves the ceramic relatively fragile. Stoneware utilises vitrified clays fired at extremely high temperatures until non-porous. These vessels are considerably heavier, naturally water-resistant, and frequently decorated with salt glazes or moulded reliefs.

How can I distinguish an 18th-century pot from a later copy?

Examine the base and interior surfaces for signs of hand-throwing marks, kiln separation scars, and natural wear patterns consistent with age. Early pieces often exhibit minor glaze imperfections and subtle asymmetries. Consult reference literature regarding specific cobalt pigments and potting weights typical of the period. Pigment chemistry and potting techniques shifted noticeably toward industrial standardisation during the nineteenth century.
