7/14/2019 monografia http://slidepdf.com/reader/full/monografia-56327b712c97c 1/9 B y analysing seven great works o architecture, we shall see how the exceptional qualities o enamelled and glazed ceramics, colour, shine and adaptation to complex shapes, are enhanced, and how they accompany and ne-tune the architect’s idea o the project. Using these properties, we shall directly relate Ceramics and the Design Decision. We shall understand when, how and why ceramic, and not another material, enters the design process o some o the most representative works o architecture. From the Ishtar Gate to Saint Catherine’s market, the examples chosen will show us that it is essential to make the material work in avour o the project’s unctional, physical and aesthetic needs, by choosing it conscientiously. Also, the importance o knowing what has been learned throughout the centuries with respect to both the tradition o ceramics and architecture itsel will be highlighted, so that rm steps can be taken, based on the development o what has already been done, to reinterpret and reprocess these achievements. Origins Ceramics go beyond the simple interpretation “made o clay”, but are to be connected to the history o almost all the peoples o the world, so much so that ceramics date sites and name cultures. Ceramics were invented during the Neolithic revolution, and they were a result o the settling o civilisations, i.e. o humankind’s bonding to a Colour, shine and shape in architectural cladding R.

particular land. At the beginning, ceramics were made using the
clay extracted rom the area, creating a bond between the land,
the cratsmen and the community.
Ceramics, as an ancient art, has evolved along with humanity’s
progress. While the clay is oten sourced locally, nowadays the
end product is usually the result o industrial processes which
orm the piece. Ceramic tiles are one o a very small number o
products which retain much o their original integrity, in spite o
the act that they are now generally mass produced by highly
technical processes.
Two o the breakthroughs that led to more aesthetic and plastic
possibilities in the world o ceramics were the enamelling and
glazing processes. Applied to the clay base, these techniques give
the ceramic piece the attributes o colour and shine.
Covering the tile body with a layer o protective enamel or glaze
opened up a spectacular range o possibilities, rstly by making it
waterproo, long-lasting and easy to clean, and by also allowing
the architect to design and combine colour and shine.
Ceramics are also extremely easy to mould. Tiles may be hand
made, extruded or dry pressed. Whichever process is adopted the
nal product is usually easy to cut. The nished product can be
installed with high quality adhesive and grout, to provide a suracethat is highly resistant to abrasion and staining
These eatures, present in other materials but exceptional in
ceramics, are colour, shine and adaptation to shape.
Ceramics, in all their variants, but perhaps especially in the
enamelled and glazed ones, ulls Steen Eiler Rasmussen’s
maxim: “as a general rule, it can be said that materials with
poor textural eects improve with a deep embossment, while
high-quality materials can take a smooth surace and, in act,
they appear more advantageous with no embossment or any
ornament ”.
But while it is interesting to know the qualities o the material
(the ingredients), it is more valuable to try to grasp how the
architect uses those qualities to enhance, accompany and ne-
tune an idea (the recipe).
Why did architects like Jørn Utzon, Enric Miralles and Antoni Gaudi,
among others, rely on ceramics to urnish an image, characterise
spaces and provide a special atmosphere or their buildings? What
makes ceramics special in comparison with other materials and
how and why was tile applied in these works?
In short, it is being able to directly relate Ceramics and the
Design Decision; to understanding when, how and why ceramics
and not another material have entered the design process o some
o the most representative works o architecture.
Deep down, it is a return journey, rom the architectural design
to the identication, classication and evaluation o the qualities
o ceramics as a construction material.
It is dicult to say when non-three-dimensional ceramicsappeared as a material inseparable rom architecture.
A remaining wall precursor is the Ishtar Gate in Babylon, clad
with thousands o enamelled bricks eaturing bulls and dragons.
But there are also others like the small mosaics ashioned rom
coloured clay that decorated walls and columns in the Assyrian city
o Nineveh, possible orerunners o the Greek stone mosaics that
would be treated in the Hellenistic era and reached perection in
the Roman and Byzantine period.
Saint Esteven of ViennaThe rst mosaics were possibly not made o stone, but o clay.
It is also possible that the rst slabs or plates or roos in Central
Europe were neither made o slate or ceramics, but o wood. There
are multiple inter-connections, oten return journeys, which bring
back improvements.
In France, Germany, Austria and other Central European countries
with heavy rains, it was the custom to cover roos with steep
slopes with wooden tiles supported on a grid o wooden strips. The
typical appearance is the one with a sh-scale structure due to the
wide overlaps that were built to prevent water rom entering. One
o the best surviving groups is in Troyes, France. It is a material that
has aged nobly with a very pleasant texture, but since it is a wood
that is exposed to the exterior, it cannot be given colour. Something
similar happens with the slate, with a strong appearance but with
a monotonous nish. While acades, doors, windows and interiors
were becoming more and more complex, the highly visible roos
with steep slopes had to be kept like uniorm drapes, in a certain
way monotonously, merely used or their unction o protectingagainst the elements.
When it was built, Saint Stephen’s Cathedral in Vienna became
the largest structure in the city. Its high, wide roos would be visible
within a radius o kilometres. Virtue arose rom necessity, since the
wide gable, ar rom imposing itsel and weighing down on the
city’s huddling houses, became its giant symbol. Its 250,000 tiles
drew the city’s coat o arms in a mosaic and gave it a colour that it
lacked. Far rom imposing a continuous solid mass on the square,
it was a light, clear decoration against which the pointed Gothic
sections were silhouetted.
On this building, ceramics acquired a type o construction that
came rom wood and slate, but which was totally in its avour.
The decision to use ceramics was rather experimental. It could
be thought that the chromatic quality o the material allowed
architects to convert what was initially a problem into a virtue:
it is possible that, when imagining the eect o the thousands
o tiles laid out in mosaic, they gave the roo an even more

pronounced slope than necessary or it to become the maineature o the square.
The same problem occurred, with the same solution, in the city
o Beaune in Burgundy, France, the most representative case being
the Hospices, a teenth century almshouse.
This desire to incorporate colour into architecture will oten be
the motive or introducing ceramics.
In the quest to distinguish public buildings rom the rest o a city’s
huddle o houses, the size or height o a tower is oten sucient,
but sometimes the grey monotony o a climate or the brownish-
grey tone o a city built entirely o the same material requires a
touch o colour, a sparkle, something that breaks the rule.
The possibilities o enamelling or through-body colouring allow
an indelible pigmentation on a product that is also waterproo.
It is true that colour can be incorporated into other materials in
the orm o paint, but this is temporary, since it requently does
not withstand inclement weather. One only needs to think o the
Greek temples, which used to be richly coloured.
Esfahan, The Blue CityThis is the case o Esahan in Iran, a symbol o the golden age o
Persian civilisation. It was designed to amaze the world, with wide
avenues and squares.
The use o tiles on walls and foors was already common in the
Middle East beore the Hellenistic period and it was revived by the
Sassanids. The Islamic use o the tile really began in the Abbasid
period, but it reached its maximum splendour in Iran ater the
18th century. In the rst stages, glazed ceramics had hexagonal
and star shapes, but then the mosaic technique, with small pieces
o cut tiles that were joined together to orm rich and complicated
drawings, was developed.
In Esahan, the large public buildings, due to their size but alsobecause o their colour, had to stand out rom the rest o the
buildings, which were structures which display the land’s natural
colours and were an integral part o the landscape.
In Esahan, at two ends o the axes o the immense Imam Square
(previously the Shah’s Square), the mosques o the Shah and
Sheikh Lot Allah stand out rom the double row o superimposed
arcades because o their intense blue colour, rather than their
size. Thus, the so-called blue city has been given its second name
rom the colour o the millions o tiles that cover the mosques’
doors, acades and domes. The dome o the Sheikh Lot Allah
mosque, with warmer tones, changes colour depending on the
sunlight, and goes rom cream to pink, taking ull advantage o the
characteristics o the textures and colours o the ceramics.
The acades sometimes give the impression o merging with the
sky thanks to the colour o the cobalt, a shade o blue that puts
an end to a return journey. Chinese ceramics, a possible precursor
o this art, which would have spread rom east to west until it

reached the Mediterranean, going through Mesopotamia and the
north o Arica, would be enriched centuries later by a colour which
had been unknown to them until that moment.
As it is perectly visible on the acades and domes o Esahan’s
mosques, another o the most beautiul eatures or experimental
possibilities o ceramics can be especially appreciated: the shine.
The double-curvature suraces strengthen this eect, which is even
more obvious when the base o the dome is built o unglazed clay.
The small sizes into which the tiles are cut, but above all the
studied geometry with which they are put together again, allow the
ceramic cladding to be adapted to the dicult shapes o the domes.
The possibility o enamelling or glazing the tile body allows us an
extremely wide variety o tones, which depends on the oxides we
use, but it also allows us to introduce shine or gloss, a very dicult
eect to obtain in other materials. Although wood can be polishedor varnished, that nish will not stand up well to the elements. In
stone materials, polishing is the process that allows us to shine
their suraces, but we also nd ourselves with limitations, since not
all stones take it and the weight and necessary thickness o the
stone pieces make it impossible or them to be applied on many
roos. Metal can have a high gloss, but in time it may rust, making
it lose its power o refection. Glass, which perorms well in terms
o cost and durability, does not adapt well to sinuous shapes.
Gaudi, Jujol and trencadisIn 1904, Antonio Gaudi designed a ceramic cladding with a gradient
o blue tones in the patio o the “Casa Batlló”, with which it blends
the light that trickles down its walls.
But it is with so-called trencadis that the Catalan architect uses
all the possibilities o ceramics, as well as colour. This technique
consists o a type o mosaic made with ragments o ceramic scrap
or with white china cups and plates joined together with mortar.

Good examples o this technique are the chimneys in the Mila and
Batllo houses and the dragon in Parc Güell, but the work in which
it is best used is perhaps the undulating white that crowns the
garden’s cornice.
Both the trencadis cladding o the bench and the ceiling o the
hypostyle hall are works o Josep Maria Jujol i Gubert, a leading
gure in the Catalan modernism movement.
The bench is made up o a series o concave and convex modules.
The base is made o white trencadis and it is crowned with a ceramicdecoration with motis that are generally abstract, but also with some
gurative elements like stars, fowers, sh, crabs, etc. This trencadis
was built with scraps, tiles, bottles and pieces o dishware. The sinuous
shapes o the bench could undoubtedly have been made o reinorced
ace concrete, but they would never refect the light o dusk in the
way the pink, blue, yellow and green ragments do.
Trencadis uses ceramics in-situ, but not in the normal sense o
“rst I know the place where it’s going to be placed, and then I
make the piece”, but in the uller, and at the same time, more
intense sense. It is not a case o new pieces to be made in situ,
but o old pieces in situ which have already been made the most
o, laid out on a drawing, which is careully designed but also
undetermined, a drawing that does not recompose the original
piece, but that, along with the extreme possibilities o colour and
shine o ceramics, makes the waves o the cornice in Parc Güell
vibrate under the changing sunlight. The shine highlights the
objective nature o the buildings and the space it covers.
As well as the aesthetic value itsel o enamelled ceramics,
architects highlight their expressive power through contrast.
The white trencadis cladding, with the largest expanse, acts as a
neutral background that validates the coloured background.
On the other hand, the repetition o the sinuous shapes made
with stone materials, which are heavier, in the rest o the park
brings to mind an empathy with the land, which, by comparison,
make the waves o the cornice made in trencadis much lighter.
In spite o using a new technique with great skill, Gaudi and Jujol
did not leap into the void. O course, they knew the stone mosaicswhich are so widespread in Rome and Byzantium, but, due to
their interests in Eastern and Mudejar architecture, stages through
which they went in their proessional career, perhaps they were
even more aware o the North Arican mosques clad in glazed
ceramic mosaic, which are much more expressive in colour than
their stone counterparts. This way o practising architecture, which
is captivated by what has been done previously, ar rom being o
little creativity, oten leads to the building o structures that better
withstand the passing o time.
Oscar Niemeyer: the Luso-Brazilian experienceOther geographically ar o experiences, but near in spirit, are
the ceramic claddings used by Brazilian architects. A particularly
outstanding case is the Oscar Niemeyer designed church o Saint
Francis o Assisi in Pampulha district o Belo Horizonte
Along with Jorn Utzon who designed the Sydney Opera House, the
Brazilian architect is one o the ew who has managed to invent
