slate etchings
Since
1997 I have been experimenting making etchings with slabs of slate.
I kept in mind that such material with it's natural laminated structure
and lack of hardness would not survive many presses and would soon
be broken under the pressure of the press.Nevertheless
it was exactly this that intrigued me and made me want to continue
observing the unique behaviour of this material.
The
slate was brought from a quarry in Germany, typical of the region
of my hometown, and I looked for pieces of varying sizes and thicknesses.
The
first difficulty of working with slate resides in the irregularity
of its surface, so I was searching for the most uniform slate pieces.
Later
in the same quarry I found , packed and ready cut, slate of varying
thicknesses, sizes and prices and was shocked to see it labelled:
"Made in Spain". I need not have travelled so far to find
my plates, they came from Spain, in a region near Alicante. They
are used throughout Europe to tile roofs.
The slate is treated with with burin and dry pointed, which is quite
laborious and needs a lot of strength in the hands, but primarily
has the advantage that the natural texture of the material is not
lost. The first time that I pressed two worked plates this way was
three years ago on Mitsuo
Miura's course at the Fundación
Pilar i Joan Miró.
At
this time it did not have my own press and the plates were broken
in the second attempt to print them, but we liked the result so
much that Miura asked me to give him one of the plates. The plate
had almost transferred an image to the paper but the excessive pressure
had caused it to break slightly however it left a very interesting
result. At this point I began to investigate the idea seriously.
I bought
a press and I began to work plates in different ways. The best results
were obtained by preparing the plates with a paste, just as the
one that is used for colografias and that is prepared with "Blanco
de España", water and glue, which once applied upon the plate,
it is possible to be treated in a variety of different ways, with
different grafismos or applying collages.
Once
prepared and inked the plate, the moment comes for finding the right
pressure so that the slate does not break immediately.
This is for me the most delicate moment, and needs to be repeated
with each new plate since each slate is different and the even the
smallest differences make a big difference to the treatment. But
this is what makes it interesting.
Ideally
it is possible to be print a few times with the slate before the
first crack appears.
With
this first crack, which of course is random, begins the adventure
and the chance, since you do not know beforehand in which direction
or place it will appear.
The
plate cracks a little more with each successive pressing until the
point is reached, in which it is impossible to remove it from the
table of the press to ink it.
Sometimes
it is at this point that the best and most beautiful press of all
can be obtained. It is completely impossible to obtain a series
of identical presses, and because of this every pressing is unique.
As
time has passed I have become more and more accustomed to this capricious
material and the surprising results that can be obtained from it,
and I believe, that there are many more possibilities than I will
discover as I work.
I presented
this technique for the first time in the Biblioteca Nacional de Madrid
with three pieces of work from the years 2000 and 2001, as well
as in the Fundación
Pilar i Joan Miró in Palma de Mallorca with a dossier y la memoria
en el año 2001 with the purpose of exhibiting a series of presses
in the "Espai Cero".
In addition a work made with this process has been selected for
the “IX
Premio Nacional de Grabado y Arte Gráfico 2001”, organised by
Calcografía
Nacional Real Academia de Bellas Artes de San Fernando, Madrid.
