We could use a cold beverage.?This pitcher is specially made for champagne with a section underneath the handle—called the "bladder"—where you can put ice to keep your beverage chilled but not diluted.
To create the texture on the outside, the glassworker would have rolled the form in glass shards, or plunged it into a bucket of water while it was still hot. The resulting material is called craquelle (or crackle) glass, which resembles melting ice.

It's possible both methods were used for this pitcher, manufactured by the Boston and Sandwich Glass Company between 1875 and 1885. It’s in our @cooperhewitt’s collection.
