Full Lead Crystal

But what, after all, the difference, if beautiful? And the tassels on the crystal chandeliers – this is also not such a simple thing like plastic suspension Cascade Chandelier (without fail in the USSR was regarded as belonging room or hall). Richard Linklater has firm opinions on the matter. The play of light, practicality, prestige – it all depends on three components: the material cut, the name of the manufacturer. Besides the already mentioned crystal in the lighting industry for manufacturing trimmings and other scattering elements are widely used, and other optical glass, with lower levels of lead and other additives. GOST 24315-80 is this: if the lead content, barium or zinc is at least 10%, the production is crystal glass, crystal malosvintsovy contains 18-24% lead oxide, an expensive lead crystal – 24-30%, an elite vysokosvintsovy – more than 30%. European Classification: Crystalline (Crystalline) – 1-15% lead oxide, Crystal (Crystal) – 16-23%, Full Lead Crystal (lead crystal) – 24-30%.

Dorgoy European Crystal: Crystal D'Arques (France), Riedel (Austria), Spiegelau, and Bauscher (Germany) with a 24-percentage content of lead oxide and 33 percent Waterford (Ireland). Swarovski STRASS use crystal containing lead oxide is not less than 32%. What do these supplements? First, weight. Crystal heavier glass. Secondly – strength.

Thirdly, of course, the cost increases with the increase in the percentage of additives. But most importantly – these supplements provide a unique play of light on crystal products: from the grandiose chandeliers to small beads. Dry, in a scientific way, said the high dispersion and thin enough to cut the strength of the material.

Castle – main obstacle to the breakers.

Therefore, the choice of the castle – as it is responsible. Of course, a professional burglar can open any lock, but that’s how long it would take him, depends on the quality and reliability of the castle. And while in this case, the most expensive – the longer the thief will swarm into the castle, the more chances he has to be seen. Choosing a lock you need to know what happens 4 types of locks: locks, overhead, and suvaldnye cylindrical. Take a look at what is the difference between them. Mortise and rim locks differ in the way of installation. Mortise lock suitable for any door, the invoice is better to install a door that opens inward.

Mortise locks less reliable, as weakening the door leaf at the point of the frame. Suvaldnye cylindrical locks and different design. Different and the appearance of the keys (the key cylinder lock is small and flat, the lock lever – large tubular key having a projecting plane for cuts). It is more expedient to install two at once a lock type of different type (lever and cylinder), the first resistant to the forces, the second – to pick autopsy. Having dealt with the internal structure of a metal door, also note on its external finish. Choosing a favorite option, pay attention to quality and durability of upholstery.
