The document discusses glass and ceramics. It defines glass as a hard, fragile, transparent amorphous inorganic material made through fusion of silica sand, sodium carbonate, and limestone at 1500 degrees. Ceramics are principally made from clay and boiling water, and have been widely used since antiquity for containers, figures, bricks, tiles, and insulation. The document notes applications of glass in construction for properties like security and insulation, and uses like windows and lenses. Ceramics have been used for containers, religious figures, bricks, tiles, sculpture, and thermal/electrical insulation.

2. Glass (Vidrio)
The glass is an
inorganic material hard,
fragile, transparent and
amorphous.
The glass is a type of
ceramic material.
The glass is obtained by
fusion at 1.500 degrees
of silica sand, sodium
carbonate and
limestone.

3. Glass applications
The glass is used in
construction. Each one is
designed to obtain certain
properties: high security,
anti-theft device,
bulletproof, fire-resistant,
against solar radiation,
thermal and acoustic
insulation, decorative
effects, etc. The glass is
used to make windows,
lens, and a big variety of
products.Burj Al Arab is a five-stars hotel in
Dubai and it is the fourth tallest hotel in
the world.

4. Ceramics, pottery (Cerámica)
Ceramics is a type of
material principally
made with clay and
boiling water, although
its mineral compose can
change when you add
other additives. It's
widely used since the
antiquity. There are
some types of clay like
earthenware, terracotta,
china, etc.

5. Ceramic applications
It first was used like a
container for foods; then it
was used to make figures
of magic, religious or
funerary character. Also it's
used in construction to
make bricks (ladrillos), tiles
(tejas), floor tiles
(baldosas), glazed tiles
(azulejos) and ceramic filler
blocks. The glazed
technique is used also for
the sculpture. Actually is
used like thermal and
electrical insulator.
Casa Batllo is a building restored by
Anonio Gaudí and Josep Maria Jujol in
the year 1877.
