New stone exhibition in France, Rocalia.
At the initiative of the magazine Pierre Actual living a new stone will be held in France. In Lyon, from 5 to 7 December, 2017.
Use of enamelled lava
The enamelled lava and stoneware are mainly used for reading tables, but can also be used for small-format plates or built-in support.
The lava has a noble aspect, a very nice texture and two centuries of use of this material, little known to the public, proved its absolute immutability signage and outdoor decoration.
Indeed, lava glazed stoneware and have a very long life. These are substances that do not know aging: they are totally unalterable by frost, acid, salt, solar and lunar radiation. They are resistant to scratches like a glass; the most resistant enamel baked several times at high temperature are rayables that diamond. The "tags" can be cleaned without altering the surface. A small downside, however, painting the tag can enter the microcracks crazing and it becomes almost impossible to remove it.
So if we know that the plate will be subjected to graffiti type of damage, it may be best to choose sandstone which does not have this crazing. Shocks pebbles leave only small traces on impact - they do not change over time inerte- on the substrate. The shotgun pellets ricochet. But a plate of enamelled lava or stoneware will not take more than another material in a violent attack to ground or chisel!
This sustainability is both an advantage and a disadvantage: it is useful in risk environment (urban area), although not resistant cases of violent vandalism, but we must take into account that any communication style old ...
The building market could stabilize in 2016 in France.
The activity of the building industry (including markets of mirrors and marble) in France could stabilize this year, which would end a "continuous slump since 2012," said Thursday the Confederation of Crafts and small construction companies (Capeb).
With a decline of 2% in volume last year, reduced to -1% last quarter, 2015 "ends with less degradation of the activity of the building crafts," announced during a Capeb press conference.
However, this is the fourth annual decline of activity in the sector, which lost another 15,000 jobs last year, lamented Patrick Liébus, president of Capeb.
"Fortunately, the 2016 outlook is less dramatic, thanks to devices for the energy performance of new and accessibility of the built," he has said.
If it is "hard to be optimistic" vis-à-vis 2016, for Capeb, it's a little more confidence, building on "a change in volume of 0-1%".
Indeed, a "less degradation in new markets and the energy renovation and accessibility, should create more favorable prospects", which would "stop the continuous slump since 2012".
For Capeb, "speak of real recovery is premature, however, while the unfair competition and lack of consumer confidence ostensibly inhibit the growth of the activity of the building crafts."
In the fourth quarter 2015, the activity in the nine still yielded 2.5% (against 5% in Q3), while it remained sluggish in eco-renovation (against -1%).
Over the whole of last year, the activity in the nine fell by 4.5%, but the sector has benefited from the growth of energy performance works (+ 1%) and the resumption of sales of existing homes .
Despite this, the maintenance and renovation activity fell 0.5%, as in 2014.
As for the improvement seen since August 2015, sales of new homes, it "should take effect sometime in 2016," said Capeb.
In early January 2016, the order books represent 72 working days, or seven days from a year earlier.
For 2016, Capeb expects a decline in activity of 0.5% to 1.5% in the nine offset by an increase of 0.5% to 1.5% in the maintenance and renovation.
The restoration of historical monuments

Understanding the past
Restoring a historical monument still born of admiration for creative work and construction that is sometimes performed many centuries. Because a book does through time if beyond its useful function residential building, defense, worship, ... magic made art and technology has exceeded its original destination.
The first work of the technicians of the historic buildings is to "grab" the magic of the place in all its dimensions. Apprehension of space, integration site-conditions for initial construction, stories of a building that has sometimes been so many assaults of men and time.
This step requires a historical research, iconographic, photographic ... with local libraries, archives, museums, universities ...
This understanding of the past depends on all the quality of the restoration, the building to its appearance but also its original spirit.
Work of art and passion, the renovation of a historic building is also an economic act. Respect for the past does not mean technological archaism; on the contrary the most modern techniques and sophisticated are used to complete the construction site.
Thus D.A.O. which will optimize stéréodomie and the work of the fitter; or even resin injection techniques that strengthen the structures without disrupting them.
The goal at this level is put at the service of a state of mind, the modern techniques which will ensure maximum reliability of the intervention as well as cost control.
Perpetuate traditions
The atmosphere as much as the look of the renovated monument depend on a multitude of details that go from the choice of materials to processing and assembly.
To make their buildings to their original shine and appearance, technicians follow the ancient building techniques.
Trained in the trades of yesteryear, the companions execute projects using conventional and traditional materials such as lime, stone or brick, if possible period.
Distinguishing features of monuments, ornaments are often the parties who have suffered most severely the action of natural erosion or that most pernicious of pollution and men.
The stonemason must then repeat the gestures that, centuries before, had given life to the same reasons, jewels, medallions, moldings ...
