Lustre Decorated Miniature Vase by Wilkinson, 1920s

• Firing Crack - A firing crack is a crack in a porcelain or stoneware item that occurs whilst the item is in the kiln.They are usually caused by faulty design, where one part is thicker than the surrounding area, and being thicker it cools more slowly, setting up a stress with the surrounding area. Firing cracks are not often seen on modern mass produced porcelain, as the damaged items are discarded during prooduction. However they are seen in earlier items and artisan-produced objects.
• Lustre Ware - Lustre decoration on ceramics is created by painting a thin deposit of metal oxide such as gold, silver or copper onto the surface, and then firing the item again, so that metal oxide forms a thin film on the surface. The finished effect is a shiny metallic surface. The technique was used in the 19th century by potteries such as Crown Devon, Grimwades, Maling, and Royal Doulton. However the best known use was by Wedgwood for its Fairyland lustre.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
