A lot of people are wrong and think it's the same thing. We tell you why this confusion.

The difference between glass and glass is a matter of order. In the crystal its components, atoms and molecules, are arranged according to an ordered system following perfectly established laws, which gives rise to defined shapes with axes and planes of symmetry; in the glass are not subject to rules, they are arranged randomly.

Crystals are created by nature and can be found in different forms, such as quartz. Most crystals are formed from the crystallization of pressure gases in the inner wall of rock cavities, instead, what is manufactured mainly by melting silica sand, is glass. There are, however, glass created by nature following the same casting procedure: like obsidian, also called volcanic glass, which is formed by the heat generated inside volcanoes; or the fulguritas, which is the result of lightning falling into the sand.

Food containers, bottles and jars are always glass. They are manufactured in industrial furnaces that melt silica sand, sodium carbonate and limestone at about 1500oC. Currently, because glass can be completely recycled, i.e. re-melt without loss of quantity or quality, glass packaging manufacturers also incorporate recycled glass – helmet or calcin – in their ovens to create new packaging, thus saving raw material and energy.

Some glasses are added certain metals, such as lead, so that their properties in terms of brightness, loudness and weight are very similar to those of crystals. This is the case with glass crockery, although it is glass we call it glass. And this confusion remains because the legislation admits to naming crystals such glasses. In particular, Spanish legislation admits to calling glasses that incorporate at least 24% lead oxide into their composition, although in rigor they are still glass, they are called crystals. 

General care for your glass cups and jugs:

- Never keep the cups face down, as the edge is very delicate and may not hold the weight.

- If your cup has any stains or dust, do not try to remove it with your finger, as you may break it by pressure. Use a sponge or cotton.

- When you wash or relocate your glasses take it by the chalice (the part where the wine is poured) not by the stem (the long part that holds the chalice) to prevent it from breaking.

- When washing, avoid the use of aroma-scented detergents, as they could alter the taste of the wine.
