The vase, just 3in (8cm) high, was part of a tray lot of otherwise modest Chinese blue and white porcelain pitched at just £30-40 at the December 7 sale.
It was identified by two bidders as a Yongzheng (1723-35) mark and period ‘melon’ form jar. Each of the six lobes is decorated with melons growing on stalks and tendrils.
A similar vase sold at Christie’s South Kensington in 2012 for a premium-inclusive £34,850.
The price represented a huge Christmas windfall for a Leicestershire resident, who put it up for auction after a clear-out at home.
The previous house record for Shouler & Son, established in 1843, was set in the 1990s when a Georgian walnut bachelor’s chest sold for £25,000.
