Descripción de la invenciónDescription of the invention

El procedimiento de fabricación de piezas cerámicas sometidas a cambios de temperatura comprende utilizar:The part manufacturing procedure ceramic undergoing temperature changes includes use:

- Un molde y echar en él un material cerámico con una humedad comprendida entre 40 y 50%. El material se distribuye uniformemente hasta alcanzar la misma altura del interior del molde.- A mold and put in it a ceramic material with a humidity between 40 and 50%. The material is evenly distributed until reaching the same height as inside of the mold.

- Se introduce el molde en una prensa y se le somete a una presión comprendida entre 900 y 1000 kilogramos/cm^{2} durante 5 a 8 minutos.- The mold is inserted in a press and it undergoes a pressure between 900 and 1000 kilograms / cm2 for 5 to 8 minutes.

- Una vez efectuado el prensado, se desmoldea, y la pieza obtenida se somete durante 12 horas a un secado en un secadero a una temperatura comprendida entre 40 y 50ºC hasta que se alcanza una humedad del 20%.- Once the pressing is done, it is unmold, and the piece obtained is subjected to drying in a dryer at a temperature between 40 and 50 ° C until it is reaches a humidity of 20%.

- Posteriormente se introduce la pieza conformada por moldeo en el horno a una temperatura comprendida entre 1200 1300ºC durante 8 a 9 horas.- Subsequently the piece is introduced formed by molding in the oven at a temperature included between 1200 1300 ° C for 8 to 9 hours.

- Se deja enfriar la pieza en el propio horno hasta alcanzar una temperatura de 300ºC.- The piece is allowed to cool in the oven itself until reaching a temperature of 300ºC.

- Se saca la pieza del horno y se deja enfriar a temperatura ambiente.- Remove the piece from the oven and let it cool to  room temperature.

- En estas condiciones, a la pieza se le aplica por su cara vista un esmalte y se la introduce en el horno a temperatura comprendida entre 1000 y 1100ºC durante 9 horas.- Under these conditions, the part is applied by its face seen an enamel and it is introduced in the oven to temperature between 1000 and 1100 ° C for 9 hours.

- Se enfría en el interior del horno dicha pieza hasta alcanzar 300ºC.- This part is cooled inside the oven  until reaching 300ºC.

- Se saca la pieza del horno y se deja enfriar a temperatura ambiente.- Remove the piece from the oven and let it cool to  room temperature.

- Sobre la superficie vista y esmaltada de la pieza se fija una fotografía y posteriormente se introduce la pieza en el horno a una temperatura comprendida entre 900 y 1000ºC, lo que favorece la fijación de los pigmentos de la fotografía sobre el esmalte de la pieza.- On the exposed and enameled surface of the piece a photograph is fixed and then the piece in the oven at a temperature between 900 and 1000ºC, which favors the fixation of the pigments of the photograph on The enamel of the piece.

Descripción de un ejemplo práctico de realización de la invenciónDescription of a practical example of realization of the invention

El procedimiento de la invención va dirigido a obtener por moldeo piezas planas cuadrangulares de unas dimensiones en su cara vista que sean, al menos, de medio metro cuadrado.The process of the invention is directed to obtain quadrangular flat pieces of a size by molding in their face seen that they are at least half a square meter.

Además, estas piezas son de material cerámico esmaltadas en su cara vista y en la que se fija una fotografía que mediante calor hace que los pigmentos de la fotografía se fijen sobre el esmalte de la pieza.In addition, these pieces are made of ceramic material enameled on his face and in which a photograph is fixed that by heat causes the pigments in the photo to be fixed on the enamel of the piece.

Por lo tanto el procedimiento consiste:Therefore the procedure consists of:

- Utiliza un molde en el que se echa el material cerámico que tiene una humedad entre 40 y 50%, y el material cerámico alcanza la misma altura dentro del molde.- Use a mold in which the material is cast  ceramic that has a humidity between 40 and 50%, and the material ceramic reaches the same height inside the mold.

- El molde con el material cerámico se introduce en una prensa y se somete a una presión comprendida entre 900 y 1000 kilogramos/cm^{2} durante 5 a 8 minutos.- The mold with the ceramic material is introduced in a press and undergoes a pressure between 900 and 1000 kilograms / cm2 for 5 to 8 minutes.

- Se efectúa a continuación el desmoldeo, obteniéndose la pieza que se somete a un secado durante 10 horas en un secadero y a una temperatura entre 40 y 50ºC hasta alcanzar el 20% de humedad.- The demoulding is carried out, obtaining the piece that is subjected to drying for 10 hours in a dryer and at a temperature between 40 and 50ºC until reaching the 20% humidity

- Transcurrido este tiempo se introduce la pieza en un horno a una temperatura entre 1200 y 1300ºC durante 8 a 9 horas.- After this time the piece is introduced in an oven at a temperature between 1200 and 1300 ° C for 8 to 9 hours.
