Sols et Paysages

Très bel ouvrage, écrit par deux passionnés, détaillant les relations entre paysages et types de sols sur une douzaine d’exemples différents.

Ce livre écrit par deux universitaires est très agréable à lire et explique en détails les principaux types de sols que l’on trouve en Europe et leur incidence sur la végétation et l’utilisation des terrains correspondants.

Cet ouvrage décrit de façon détaillée un grand nombre de sols en croisant les observations sur le terrain, les analyses en laboratoire et en s’appuyant sur la bibliographie et l’expérience des deux auteurs. A partie de ces données sont expliquées la formation du sol et ses incidences sur la végétation et l’exploitation des terrains correspondants.

L’incidence de l’habitat, de l’agriculture, de l’exploitation du sous-sol sont prises en compte ainsi que leurs incidences sur le sol.

Une autre partie traite plus en profondeur les usages du sol qu’ils soient urbains, forestiers, agricoles, viticoles ou autres.

Ce livre est abondamment illustré de photos et croquis.

Il s’adresse à tout professionnel ou futur professionnel dans ce domaine ou dans des domaines proches (agriculture, exploitations forestières ou minières…) mais aussi à toute personne convaincue de l’importance du sol et de l’impératif de le protéger.

Very strong growth in Internet sales of wheels for mirrors machines.

Vedip, the first European web site (French origin) Internet sales of Italian wheels for mirrors machines saw its revenues for the second 2019 quarter  increased by more than 67 %.

The strategy developed by Vedip to propose, in partnership with a leading Italian manufacturers of wheels and diamond core drills for glass, very competitive prices  for working only on the Internet, detailed fact sheets with photos, standard wheels made by manufacturers / Machines / Positions, alternative wheels and a telephone support seems to meet the needs of the market in Europe mirrors.

The site already has 1741 tools now online  continues  to improve the technical data of the tools and the number of referenced machinery (over a hundred).

On Vedip you can view the data sheets (with photos and price) of the wheels for the main flat glass processing machines of the market (straight line edging machines, CNC, drills, double edger, chamfering ...) and the most important suppliers (Intermac, Bovone, Glaston, Bavelloni, Lattuada, Schiatti, JANBAC Baudin, Battelino, Denver, Bimatech, Ada, Besana, Bottero ....).

Glass story : the first steps

 

In the nature the glass exists :

-It can come from :

-volcano

The obsidian (generally green or black) has been used during the prehistory (the oldest tools with obsidian has been manufactured 100 000 years ago) and changed in tools, weapons, jewels, mirrors (inside which it was possible to see his own soul!)

Obsidian piece.

 

Obisidian knive.

 

 

Obsidian jewels

 

-from meteorites

 

 

When a meteorite drops on sand

-From the lightning, when a lightning flash touches sand

 

 

Every time glass is created it is because there are extreme temperature and pressure conditions.

But a lot more amazing is that glass is also synthesized  in very large quantities in ocean by seaweeds or inside some sponges skeletons.

 

Yes it is glass!

 

Seaweeds called "diatomés" have a very delicate glass shell. The glass synthesis is done here by a chemical reaction.

 

"diatomées".

 

The glass production from seaweeds is huge, a lot more important than the industrial production.

This organic glass is also called "opale" used in jewelry

 

 

 

Two Opales samples.

 

But the oldest glasses have been discovered on ….the moon during the Apollo missions.

 

Glass discovery:

The glass was discovered by accident during metal working or inside potter’s furnaces.

The metal working is going to remove the glass from the weapons or tools using to focus it in jewelry, decoration or religious using.

 

The oldest glasses coming from human work are from 3000 years before JC. Some small statues, beads and jewels were found in Middle East.

During this period the glass is not transparent because the impurities remaining inside the glass.
