This is what the tea that was dumped into the Boston Harbor would have looked like. In the 1700s, tea was compressed into planks; a plank this size could last a person roughly a year. They would be bought in sections, and small slivers would be shaved off into the kettle every time somebody wanted to make a cup of tea.
what the fuck that’s so neat
I want to take a bite out of it.
Sorry, but apparently no. (OP’s source link is just imgr – I’m linking the Boston Tea Party Ship (museum) site, which isn’t academic but does cite their sources. The tea bricks are real, though! They just weren’t the form commonly imported to the West in that time.)
