How can I tell if a porcelain vase is antique?

There are a few ways to tell the approximate age of a porcelain vase, including identifying the maker's mark. These are usually located on the bottom of the vase. The maker's mark can help you find the era of manufacture once you know the company or studio that produced the piece. Look for imperfections, which were inevitable with wood-fuelled kilns of the past but uncommon with modern gas-fuelled kilns.
