对于大部分准备购买酒杯的消费者来说，下面这些基本常识是很有用的。

全文如下：

    人们习惯把葡萄酒杯笼统称为高脚杯。但爱酒的人，对于酒杯也不肯有一丝马虎。挑一个酒杯的认真态度不亚于挑选一瓶酒。有必要吗？相当的有必要。

    葡萄酒杯的形状多为底大而杯口微缩，目的于晃杯时容易兜住酒液，避免洒出，同时，有助于敛留香气。饮什么样的葡萄酒用什么样的酒杯，红酒杯与白酒杯不同，就算同样是红酒，饮酒的杯子亦有区别。这就是饮酒人所谓的量体裁衣。先不说喝什么酒用什么酒杯，先说说玻璃杯与水晶杯。

    品酒的人，多用水晶杯，但初学者通常分不清楚玻璃杯和水晶杯有什么区别。或许，要说，价格不同。当然，价格肯定是不同，但不识货，花了钱也不一定买到对等的杯子。

首先、玻璃与水晶

    水晶，分为天然水晶和人造水晶。

    天然水晶产量比较大，学名二氧化硅，一般用来做工艺品。

    人造水晶，通常就是加入了氧化铅的玻璃。氧化铅含量达到24%以上，折射度达到1.545就称为人造水晶。广义的人造水晶包括铅水晶玻璃、钡水晶玻璃、锌水晶玻璃、钛水晶玻璃和锆水晶玻璃以及混合型水晶玻璃。通常简单说来，就是含铅水晶和无铅水晶。

    玻璃，日常生活中所用的玻璃大多是以SiO2为主要成分的硅酸盐玻璃，由熔融物冷却、固化等到非晶态固体。

    水晶玻璃和普通玻璃的化学成分差别，导致了两者质地、折射率的不同。

    用于制作水晶杯的水晶玻璃，含铅量在24%好处是增加了重量，有质感，更通透、清澈和明亮。

    但也有缺点，那就是较软、易磨花。主要的铅中毒，长期使用含铅水晶杯盛放酒类、汽水、蜂蜜或果汁等酸性饮料或食物，会产生对人体有害的化学物质，导致慢性铅中毒。

    欧盟2000年起，出台明文禁令，停产全线含铅水晶杯。所以，欧盟境内，绝对找不到一家生产含铅水晶杯的厂商。现在欧盟的水晶杯是水晶琳制品，即含钾玻璃制成，超越含铅水晶玻璃。

其次、水晶杯与玻璃杯的鉴别

水晶杯质地细腻、明亮、反光，有弹性，一款做工好的水晶杯薄如纸、声如磬。可以从以下几个方面鉴别：

  第一、手感

触摸，水晶杯比玻璃杯凉爽。因为水晶导热性能比玻璃强，所以传递给指尖的触觉也不相同。水晶杯有一定弹性,轻轻挤捏杯沿，可以感觉到杯子的变形。当然，玻璃杯会被捏碎，所以千万别用蛮力，否则……

  第二、看光泽

水晶玻璃可以吸收光泽，甚至紫外线，举起水晶杯对着光线旋转，晶莹剔透，折射出五彩光线，就像看一件水晶工艺品。普通玻璃对光线的折射率和透光率不同，对于光线的反射效果也区别明显。

  第三、看杯口

杯口边缘略突出，像是缠着一道细箍，细箍如细粉丝，通常称为粉丝杯口。这就是玻璃杯，因为粉丝是热切时玻璃液回流所形成的水晶杯的杯口是冷切出来的通常经过打磨，因而多为光滑的

  第四、掂轻重

水晶杯通常薄如纸，拿在手中有轻盈的感觉。而玻璃杯多杯壁厚实，拿在手中有沉甸甸的感觉。当然，随着制造工艺的先进，玻璃杯也越轻巧了所以这一条不能当做绝对的衡量标准。

  第五、听声音

轻敲或轻弹杯子，玻璃杯是发闷的咔咔声，两杯相撞声音沉闷。而水晶杯声音清脆如金属声响，并有穿破空气荡漾出优美的余音。两杯相撞，清脆且回音长。

无铅水晶比含铅水晶有更好的折光性，轻弹发出的金属声也更悦耳，关键是比含铅水晶更有韧性耐撞击。当然，最主要的对人体更安全更可靠。这种水晶杯价格也偏高。

国内对于水晶器皿的制作缺乏规范的管理，没有水晶器皿的国家统一标准。市面上便宜的水晶酒杯，建议不要购买。还不如直接用玻璃杯更安全。购买水晶杯一定要选择无铅的

Habits, it is generally known as the wine glass goblet. But people who love wine, for wine is not willing to have a trace of sloppy. Pick a selection of glass no less serious about a bottle of wine. Necessary? Quite necessary.

Wine cup shape of the bottom large cup miniature, easy to aim at the cup Akira Douzhu wine, to avoid throwing out the same time, contribute to convergence to stay aroma. What kind of wine to drink with what kind of wine, red wine and white wine glass is different even if the same wine, and drinking cups are also different. This is the so-called tailor-drinkers. Not speak of what wine to drink with what wine, let us talk about glass and crystal glass.

 Wine people, the use of crystal glass, but beginners often could not tell the glass and crystal glass What is the difference. Perhaps, say, the price difference. Of course, the price is certainly different, but do not know what's what, spent the money does not necessarily get to the other cup.

First, glass and crystal

Crystal, divided into natural and artificial crystal crystal.

Production of relatively large natural crystal, generic silica, generally used for crafts.

Artificial crystal, usually added lead oxide glass. Lead oxide content of 24%, and reflects the degree to 1.545 is known as man-made crystal. Broad, including man-made lead crystal glass, crystal, barium crystal glass, crystal glass, zinc, titanium, zirconium crystal glass and crystal glass and mixed crystal glass. Usually simple, it is a lead crystal and lead-free crystal.

Glass, used in daily life are mostly based on SiO2 glass as the main component of silicate glass by the melt cooling, curing until the amorphous solid.

Ordinary glass, crystal glass and the chemical composition of the difference, resulting in both texture, refractive index difference.

Used to produce crystal glass crystal glass, lead content in 24% of the benefits is to increase the weight, texture, more transparent, clear and bright.

But there are also disadvantages, that is soft, easy to wear flowers. The main lead poisoning, long-term use of leaded crystal wine glass in full bloom, soft drinks, honey or fruit juice and other acidic drinks or food, will produce harmful chemicals, leading to chronic lead poisoning.

EU 2000, issued decree, across the board cut lead crystal glass. Therefore, within the European Union, will not find a manufacturer of lead crystal glass manufacturers. The EU is now crystal glass products, Crystal Lynn, that potassium glass, lead crystal glass beyond.

Secondly, the identification of crystal glass and glass

Crystal cup fine texture, bright, reflective, flexible, a good crystal glass as thin as paper work, such as chime sound. Can be identified from the following aspects:

First, feel

Touch, crystal cup cooler than the glass. Because of stronger than glass crystal thermal conductivity, it passed to the fingertip touch is not the same. Crystal glass has a certain flexibility, gently squeezes rim of the glass, you can feel the cup deformation. Of course, the glass will be crumbled, so do not use brute force, or else ... ...

Second, look shiny

Shiny crystal glass can absorb, and even ultraviolet light, lift cup to the light crystal rotation, crystal clear, colorful reflection of light, like watching a Crystal. Ordinary glass of refractive index and transmittance of light is different for the light reflection effect is the difference obvious.

Third, look at the cup

Slightly prominent edge of the cup, like wrapped around a small hoop, small hoop, such as small fans, often referred to as fans cup. This is the glass, because the fans are eager to return the glass formed by liquid crystal cup of the cup is cut out of the cold usually polished, and they tend to smooth

Fourth, weigh the severity of

Crystal glass is usually thin as paper in my hand a light feeling. The more Beibi thick glass in my hand a heavy feeling. Of course, with advanced manufacturing processes, the more light the glass so that one can not as an absolute measure.

Fifth, listen to the sound

Tap or flick the cup, glass is a muffled sound of Kaka, two cups of collision sounds dull. The crystal cup crisp sound, such as metal sound, and has pierced the air waves a beautiful lingering. Two cups of collision, crisp and echo long.

Lead crystal Lead crystal better than the refractive index, issued by the flick more pleasant metallic sound, the key is more resilient than lead crystal impact-resistant. Of course, the most important human safer and more reliable. This crystal glass prices are high.

Domestic production of crystal ware for the lack of standardized management, there is no national uniform standards of crystal ware. Cheap crystal glasses on the market, it is recommended not to buy. Not as the direct use of glass safer. Must choose to purchase lead-free crystal glass.
