2. European colonial luxuries

By 1800, Europeans could see the Age of Discovery’s impact everywhere – except, apparently, in their standard of living. Spices from Asia added flavour to meals; tomatoes transformed Mediterranean diets; and potatoes provided a new and cheap source of calories. Coffee, tea and chocolate were enjoyed by the upper classes, and increasingly, lower down the social scale. Silver from the Americas was used for coins. Sugar from the Caribbean sweetened hot beverages and preserved the fruits of summer as jam and marmalade. Cod from Newfoundland arrived on European tables by the boatload. European fleets and armies fought each other in the far-flung corners of the earth in a struggle for global supremacy. Many scholars have thus concluded that globalization began in 1492.
At the same time, the Age of Discovery apparently did not improve European living standards. Profits from transatlantic trade were small and overseas trade did not change factor prices before the 1830s.  The supply of raw materials from the New World was also unimportant. Thus, Europeans lived none the better as a result of the discoveries; per capita incomes stagnated prior to the Industrial Revolution, or even declined.
The Age of Discoveries raised European living standards importantly through gains from variety. Global trade after 1500 mattered not because the quantities involved were large, but because of the novelty of the goods traded. The ‘Columbian Exchange’ made life sweeter and more stimulating, by bringing sugar, tea, chocolate, tobacco, and coffee to European tables. Early modern consumers increasingly voted with their pocketbooks in favour of these goods –aggregate consumption of colonial.
Around 1750 only about 5% of Europeans were drinking tea, coffee or chocolate morning and afternoon and this created a limited demand for place settings to match the this upper class cultural distinction (Table 1).   In a century from 1700 the price of coffee had fallen to a third.  But there was no increased demand until the last decade of the 18th century, when it went up ten-fold (Fig 4). This rise was probably due to the spread of a coffee-drinking culture.  The ceramics industry responded by searching for new ways to bring down the price of table settings.

Export porcelain continued to be produced in China into the 1700s. However, during the eighteenth century the techniques of blue and white production were taken up by pottery manufacturers in the West. This resulted in cheap mass production of blue and white transfer patterned pottery in the UK. The most famous pattern is, of course, the ‘willow pattern’, which was designed by Thomas Minton in about 1790. The original pattern features a willow tree, a bridge with three figures crossing, a boat, a pagoda or two, a garden and a fence. Slightly later patterns also show two birds in flight. Mass production of pottery featuring this pattern made items more affordable to middle and working class households, and established willow-pattern crockery displays on open shelves.
Since then the way these luxuries are grown and processed has profound environmental importance both locally and internationally.  Four themes are intimately related: biodiversity and conservation of forest ecosystems; agro-chemical use; water pollution from coffee processing; and soil quality. Each of these factors is critical to environmental quality.
