By 1714, the thumb-piece on English serving pots had disappeared, and the handle was no longer set at a right angle to the spout. English coffee-pot bodies showed a further modification in 1725, the taper becoming less and less.

Coffee grinders were so common in France in 1720 that they were to be had for a dollar and twenty cents each. Their development by the French had been rapid from the original spice grinder. At first, they were known as coffee mills; but in the eighteenth century, roasters came to be known by that name. They were made of iron, retaining the same principle of the horizontal mill-stones—one of which is fixed while the other moves—that the ancients employed for grinding wheat. They were squat, box-shaped affairs, having in the center a shank of iron that revolved upon a fixed, corrugated iron plate. There was also the style that fastened to the wall. At first, the drawer to receive ground coffee was missing, but this was supplied in later types. Before its invention, the ground coffee was received in a sack of greased leather, or in one treated on the outside with beeswax—probably the original of the duplex paper bag for conserving the flavor.

The French brought their innate artistic talents to bear upon coffee grinders, just as they did upon roasters and serving pots. In many instances they made the outer parts of silver and of gold.

By 1750, the straight-line serving pot in England had begun to yield to the reactionary movement in art favoring bulbous bodies and serpentine spouts.

About 1760, French inventors began to devote themselves to improvements in coffee-making devices. Donmartin, a Paris tinsmith, in 1763, invented an urn pot that employed a flannel sack for infusing. Another infusion device, produced the same year by L'Ainé, also a tinsmith of Paris, was known as a diligence.

A complete revolution in the style of English serving pots took place in 1770, with a return to the flowing lines of the Turkish ewer; and between 1800 and 1900, there was a gradual return to the style of serving pot having the handle at a right angle to the spout.
