Port tongs are a special set of tongs designed to open wine bottles that are sealed with a cork. The tongs are heated over an open flame and held against the neck of the wine bottle for 20–30 seconds. The heated section of bottle is then cooled with a damp cloth or ice water, causing the glass to fracture due to thermal expansion. The result is generally a clean, predictable break. Any possible shards of glass are strained out, along with any sediment, when pouring the wine into a decanter. The tongs are intended for use when the cork cannot be removed with a normal corkscrew, such as old corks that would break apart and crumble into the wine.[2]
