Dear Anne,

What you have here are so called Nanking ware ginger jars made for export in China around 1900 / 1910. You have two types of Nanking ware; polychromic and blue / white. The blue white one's are usually more appreciated in the market and prices are a little higher for those wares. The crackle in the glaze is deliberately done in the making process by cooling the glazed pot quickly in cold water. The crackle appears due to the ''scare up'' of the glaze. You did not mention the height of the pots and that is important for the price. My estimation is based on my assumption the pots are 15 cm high. If they are less high price will drop a little. A pot of 20 / 25 will be doubled in price. The pot on the right will do 60% of the estimate and the one on the left will do 40%. The brown ring in the glaze is not so much appreciates as without.
