Introduction
Ceramic tile is a building material unparalleled for its combination of practicality
and beauty. For centuries, it has been
used to adorn humble kitchens and
majestic palaces. Its values have
remained unchanged. What has
changed, however, is the variety of
ceramic tile offered. New technology has
introduced an ever-widening selection of
tile for almost every application.
As the world’s leading manufacturer of
ceramic tile (with an yearly production
of 600 000 000m2), Italy is at the forefront of design and technological innovation. New firing techniques produce
tiles suitable for tough industrial installations. New glazing techniques produce
floor tiles in colors and finishes never
before possible. Tile size can range up to
4
Introduction
60cm2. The variety of shapes is nearly
endless.
Today, Italy produces 43% of tile in
international commerce, supplying contractors and dealers around the globe.
As the variety of tile and its application
has increased, so have the terms and
nomenclature used to describe it. In
addition to the abundance of newly
coined expressions, there is a great latitude in commonly used terminology. A
contractor’s term may be understood differently from a layman’s term or that of a
retailer.
This dictionary is intended for everyone
involved in the selection and installation
of Italian ceramic tile, from the dealer
and contractor to the consumer and
5
specifier. It is a two-part reference tool.
In the first section, definitions are supplied for the most frequently encountered trade terms – from production to
end-use. The second section supplies
translations of these terms from English
to Italian and vice versa.
We hope that this dictionary will contribute to the user’s knowledge and
enjoyment of Italian ceramic tiles.

Classification and M
of Italian Ceramic T
Notes
Ceramic tiles are derived from mixtures of clay, sand
and other natural materials that are shaped into slabs
and fired at high temperatures, up to 1250° C. Their
composition is the same as that of all ceramic material,
from tableware and sanitary ware to roofing tiles. Like
all ceramic material, ceramic tiles are durable, hygienic, non-combustible, fire-resistant, and easy to maintain. Tiles are also rigid and feature relatively low
resistance to shock. These features are intrinsic to the
nature of ceramic materials.
As floor and wall covering, ceramic tile serves a dual
function: an aesthetic function as a design component
and a technical function as a finishing building material. As a building material, ceramic tile must be able to
withstand a range of environmental stresses. Features
defined by international norms govern the technical
function of ceramic floor and wall tiles.
1 - Classification and application
According to current international norms (ISO13006),
ceramic tiles are classified into 9 groups based on two
features: the level of water absorption and the shaping
method (see Table 1). This simple classification is warranted given the extremely wide range of products
9
Manufacturing

with different trade names and countries of origin.
The chosen features are also significant factors in
defining the performance specifications of the different products.
As will be discussed later, there are norms and acceptance requirements for standardized characteristics
within each group.

In the new ISO norms (ISO 13006), the group BI is
devided in two subgroups: BIa (W.A. ≤ 0,05%) and
BIb (< W.A. ≤ 3%). In addition to the ISO norms,
other well-established classification systems (technical
and artistic) are still used in trade. Table 2 shows the
technical-commercial classification used in Italy.
Most ceramic tiles are shaped by dry-pressing (B
groups). About 95% of tiles produced in Italy are dry-
10
Classification and Manufacturing of Italian Ceramic Tile
pressed. Their usage can be roughly outlined as follows:
- Unglazed tiles (clinker, cotto, red stoneware and
porcelain stoneware) are used mainly for floors.
Clinker and porcelain stoneware have also been successfully used on walls, particularly in exterior applications.
- Majolica and white body-earthenware are typical
materials for tiling indoor walls.
- Single-fired tiles (red and white body) are generally
used for floors. However, in recent years, “monoporosa”, a porous single-fired material, has been
developed for wall applications.
- Cottoforte is used for tiling indoor floors and walls.
- Vitrified, dry-pressed tiles (BI) and extruded tiles,
mostly unglazed (clinker and cotto), are used mostly
in exterior installations.
This outline demonstrates the range and variety of
product types that can be included in the classification
of ceramic tile for floors and walls. The range of technical and aesthetic features and of the performances
by the different types is vast as well. The performance
range in particular has expanded in recent years,
thanks to the development of glazed and unglazed
products with superior resistance to a variety of environmental stresses. Once relegated to kitchens and
baths, ceramic tile is now a viable alternative for any
11
public and industrial application. The versatility of
ceramic tile is further enhanced by the almost endless
range of colors, textures, and decorative motifs, and
by the range of sizes from less than 10 x 10cm to more
than 60 x 60cm.

2 – The Manufacturing of Ceramic Tile
Raw materials for the body: The range of tile bodies is
as vast as the above-mentioned range of products.
Majolica, cottoforte, red body single-fired products,
cotto and red stoneware are mainly obtained from a
natural mixture, i.e. a mixture of few clays coming
from the same quarry. White or light body tiles (earth-
12
Classification and Manufacturing of Italian Ceramic Tile
enware, white single-fired products and porcelain
stoneware) are obtained from mixtures prepared in
the factory. Illitic and kaolinitic white clays, calcite and
dolomite, sand, talc and feldspars generally form the
earthenware body.
Mixtures of kaolin, white-firing plastic clays, feldspars
and sands are used for white single-fired products and
porcelain stoneware.
Body preparation: The dry process with traditional
wetting is generally used for all products obtained
from a single raw material (majolica, cottoforte, red
stoneware). The dry process with granulation is used
for medium-sintered or porous red single-fired products to be fired in slow-firing kilns. The wet process
(wet grinding and spray drying) is used for all the
white body products (earthenware, white single-fired
products, and porcelain stoneware) and for red singlefired and highly vitrified products to be fired in fastfiring kilns.
Shaping: With the exception of cotto and clinker,
which are shaped by extrusion, all types of ceramic
tiles are shaped by dry-pressing, generally with
hydraulic presses.
Drying: Hot-air, rapid dryers are most commonly used.
13
Glazes and glazing: Glazes are mixtures of frits, sand,
kaolin, coloring agents and opacifiers, mostly applied
wet using different systems. Decoration is often
obtained by silk-screening. The double-firing technique, in which glaze is applied to the previously fired
body, is still used today for products in majolica and
cottoforte. In the single-firing method, glaze is applied
to the dried raw body before firing. Many innovative
techniques have been developed to improve the
mechanical features of the glazed surface. Some of the
most important are dry applications and press-glazing
(the application of the glaze in powder form when
pressing the tile body).
Firing: Single-layer fast-firing kilns are used for most
products. The firing temperatures range between
1000-1020° for porous products; 1050-1100°C for red
single-fired products; 1150-1200°C for white singlefired products; and 1200 –1220°C for porcelain
stoneware.
3 – Characteristics and norms
The characteristics that ceramic floor and wall tiles
must have, according to their intended use, are indicated and classified in Table 3. The norms currently in
force require their check.

Without examining all the characteristics in detail,
some general aspects should be noted.
• Water absorption, a measurement of open porosity,
is one of the determining parameters in the technical
classification of ceramic tiles. Porosity significantly
influences many other characteristics and, therefore,
the performance of the product.
• Water absorption is an important aspect in determining frost resistance. Not only the quantity of
pores, but also their size must be considered. In
dry-pressed ceramic tiles, which feature roughly
round and generally small pores, a lower absorption
level reduces the risk of frost damage, as in porcelain stoneware, with a water absorption level of less
than 0.5%.
• The mechanical and chemical characteristics of
glazed tiles surface depend on the composition and
microstructure of the glaze which also affect its
durability. Micropores in the glaze can contribute to
surface damage, such as ingrained dirt, as wear
increases. However, as mentioned above, in recent
years, innovative glazing techniques have been developed that have improved the glaze microstructure
and produced glazed tiles capable of withstanding
16
Classification and Manufacturing of Italian Ceramic Tile
the high levels of chemical and mechanical surface
stress often present in contract and commercial
flooring applications.
• Finally, it should be noted that in addition to features defining ceramic tile performance in a given
installation, the new ISO norms also require checks
for features relating to ceramic tiles’ impact on the
environment and safety in use.
