A massive silver-gilt wine cistern, on a spreading base with scroll feet, cast all over with shells and rocks, and covered throughout with applied Bacchanalian groups; at each end are groups of infants at play; the handles are cast as lion and unicorn supporters; the interior is engraved with the arms of George IV.

The largest piece of wrought English plate in existence, the Punch Bowl weighs 8,000 oz, and cost £8500. It was designed by Thomas Stothard as the culmination of George IV's great dining service - the Grand Service - although the King did not live to see it delivered to Windsor Castle. It was first used at William IV's 65th birthday dinner in 1830. Accounts of the dinner note that John Bridge himself attended, and hid behind the wine cooler during the course of the meal, in order to oversee the plate in use without being seen himself. Queen Victoria converted the wine cooler into a punch bowl, commissioning a massive ladle to accompany it. It was used to celebrate the christening of her eldest son, Prince Albert Edward, in 1842.
