TILE WORK OF THE 17th and

18th CENTURIES

Migration of techniques and styles

HE HISTORY

of what we have largely

come to recognise as the 17th- and

18th-century tile work of northern

Europe is a fascinating trail of migrating

communities and craft techniques.

Glazed ceramic tile- and brick-making

is an ancient art first found in Egypt,

Mesopotamia and China. Tile-making

among the Islamic cultures of North Africa,

the Middle and Near East was, and still

is, widespread, as are tiles originating from

medieval and modern Spain, particularly

Talavera de la Reina, Toledo, and the Triana

district of Seville. This strand of tile-making

can be traced from Moorish Spain and also

from Italy up into Holland and the Low

Countries at the beginning of the 16th century.

The Portuguese tradition of tile-making

was inextricably linked with both Flemish

tile-making and the Moorish tradition

throughout the 17th century. Flemish ceramic

artists of the highest calibre travelled to

Portugal to work on royal interiors. The

exchange of talent and technique between

southern and northern Europe was

commonplace for over three centuries.

The Spanish tradition migrated across to

Mexico and later into California. The Dutch

and Low Country tradition first appeared

in London during the mid-16th century as

people fled wars of religious persecution.

However, it wasn’t until the 18th century

that the technique for tile-making firmly

established itself in Britain with centres in

Liverpool, Bristol and London. Thousands

of tiles were also imported from Holland in

response to the soaring popularity of ‘Delft

tiles’ (although, as we will see, the term Delft

can be misleading).

By the mid-18th century the industry in

England was at its height and, in addition to

the home market, tiles were shipped in their

thousands from the ports of Europe across the

Atlantic to the Dutch and English east coast

settlements of the New World.

Tile-making continued in Holland, where

it still survives. The English scene saw the

slow decline and end of the ‘Delft’ tradition

as developments in the English ceramics

industry began to produce the robust and

distinctive product which eventually became

the Victorian tile.

There was a brief revival of imported

Dutch tiles between 1890 and 1910 when they

were favoured by Morris & Co and other

Aesthetic Movement designers.

MANUFACTURE AND USES

The Spanish and Delft styles of manufacture

are broadly speaking the same: a twice-fired,

hand-decorated, tin-glazed tile. However, it

is the later, northern hemisphere examples of

manufacturing technique and conservation

that will be the focus of this article.

The city of Delft, in Holland, was

generally thought to produce the best

tiles so ‘Delft’ has, over time, become the

commonly used generic term. English

tile-makers went to great lengths to make

their product indistinguishable from

the Dutch tile and it requires an expert

eye to differentiate between them.

In Holland, Spain and Portugal

elaborately hand-painted tile panels were used

as interior and exterior decoration in their

own right (above). However, in England their

use seems to have remained firmly utilitarian

in dairies and kitchens although they were

used more decoratively in fireplace surrounds

(see page 177, second illustration).

The clay used for ‘Delft’ tile-making

is specific, it tends to be rich in calcium

carbonate and fine sand deposited as silt from

river beds and has added marl (a naturally

occurring sedimentary clay). This produces

a tile which is light in weight and tends

towards porosity. Clay was usually dug locally

but, as with all large-scale ceramic industry

production, imported clay often eventually

replaced locally dug clay.

The clay was weathered in the open air

over a period of time, allowing the natural

actions of frost and rain to break down its

solid mass. The production technique began

with rolling and ‘pugging’, mixing and folding

the wet clay to remove stones, impurities and

small pockets of air. The wet clay was then

rolled out onto a sanded board to thicknesses

as little as 6–7mm, allowed to dry leather-

hard and cut into squares. After a further

drying period the undecorated tiles were

put into a kiln for the first biscuit firing to

temperatures of up to 1000°c to produce a

hard ceramic object.

The biscuit tile was then ready for glazing

and decorating. Tin glaze is prepared from a

clear lead glaze with added tin oxide, which

gives the glaze an opaque white colour. Shades

of white could vary widely and eventually

sand and an alkali were added to glazes to

consolidate and strengthen the final product.

Traditional glaze colours for decoration

were produced by adding cobalt to produce

Despite the complexity of the repeated pattern on these Delft tiles, the hand-painting displays an easy, flowing style.
