تفاوت بین شیشه و کریستال چیست؟
If you're planning a full course meal for an elegant event or looking to add a sophisticated touch to a romantic dinner, you may find yourself headed to the china cabinet to pull out the good crystal. Crystal glass has long been associated with high-end dining, but why is it considered more luxurious than standard glass? Below we'll clarify the difference between crystal and glass to help you set the table for your next event.
کریستال در مقابل شیشه
When comparing glass vs crystal, crystal is a type of glass that contains strengthening minerals like lead-oxide, potassium carbonate, and silica to make the material durable. The added strength allows the crystal to be molded into thin, delicate shapes. Standard glass is usually made with sand, soda ash, and limestone, making it durable but unable to be molded as thin as crystal. Crystal is also able to refract light while glass will typically lack that ability, making crystal more sought out for formal table settings and more expensive than glass.
شیشه چیست؟
شیشه یک ماده شفاف است که می توان آن را ذوب کرد و به شکل های جامد درآورد. از ماسه، خاکستر سودا و سنگ آهک ساخته شده است، اما مواد معدنی دیگری مانند سیلیس و باریم را می توان برای دستکاری رنگ، دوام و ضخامت آن اضافه کرد.
Glass with a low mineral count is non-porous, which makes glass dishwasher safe and heat-resistant. Some popular types of glass used in public settings are borosilicate glass, commonly used for glass food storage containers, and fuzed quartz glass used for camera lenses and lab equipment.
کریستال چیست؟
شیشه کریستال ماده ای شفاف است که با همان مواد تشکیل دهنده شیشه ساخته می شود، اما با افزودن اکسید سرب-یا فلز-. مواد اضافی باعث می شود که کریستال یکپارچگی خود را حتی در هنگام برش یا دمیدن حفظ کند. مواد افزوده شده در شیشه کریستال، مواد را کمی متخلخل می کند و به آن توانایی شکست درخشان نور را می دهد. با این حال، این همچنین به این معنی است که این ماده قابل شستشو در ماشین ظرفشویی نیست.
Crystal is produced by companies around the globe and can be made with varying levels of lead-oxide. Unlike the name suggests, crystal glass does not actually contain a crystalline structure in its material compound. The name is derived from the Italian term "Cristallo", which was used for high-end hand-blown glass in Murano, Italy. Its association with sophistication makes crystal desirable and higher in price than glass.
تفاوت بین شیشه و کریستال
شیشه و کریستال هر دو با حرارت دادن در کوره تا مذاب ساخته می شوند. سپس توسط شیشه دمنده دمیده می شوند و به طرح های دلخواه در می آیند. با این حال، این دو ماده دارای تفاوت های مختلفی هستند، از ترکیب شیمیایی و وزن آنها گرفته تا نحوه شکست نور و بازتاب صدا. ما نگاهی دقیق به تفاوت آنها در زیر می اندازیم تا روشن کنیم که چرا کریستال قیمت بالاتری دارد.
تفاوت های ظاهری
Glass: Glass is often slightly foggy in appearance and can typically feature a tint based on the ingredients in its composition. It can have a green tint if made with iron or a blue tint if made with soda-lime.
Crystal: Crystal boasts incredible clarity, which makes it a desirable choice for high-end glassware and decorations.
تفاوت وزن
Glass: Glass is lighter in weight in comparison to crystal pieces of the same design.
Crystal: Because crystal contains lead or other metals, it tends to be heavier in weight than standard glass of the same design.
تفاوت ضخامت
Glass: Due to the soda-lime in its chemical composition, glass requires a high working temperature and hardens rather quickly after being heated, which results in a thick rim. The material is more fragile than crystal so most cup rims will be reinforced for added strength.
Crystal: Crystal can be heated at lower temperatures than glass because of the lead and potassium carbonate in the composition. This allows for the glassblower to more easily work the material and make it thin. The additional chemicals also help the material to remain strong while being stretched further than glass.
برش تفاوت ها
Glass: Since glass hardens more quickly than crystal, it offers little time to be cut by hand. The material is generally too hot to manage with gloves so glass is typically bent into shape while hot or blown into a mold. Any cuts on the surface are usually sharp, rigid, and brittle.
Crystal: Since crystal is strengthened by its minerals, it is soft enough to add smooth hand-cut details to its surface without compromising its durability. The material is more malleable than glass, allowing the artist to add intricate patterns. The cuts can then be buffed and polished without fear of shattering the structure.
تفاوت های انکساری
Glass: Glass has very little metal content, which means that light will pass through like a windowpane without refracting. The soda-lime in glass lacks retracting abilities.
Crystal: Because of the lead and metal content in crystal, the material can refract light that passes through it in the right position. Light disperses from crystal in a rainbow hue, making the material desirable for decorations and tableware.
تفاوت صدا
Glass: Glass provides a dull chime when tapped or flicked. The sound is usually short in length and subtle.
Crystal: When tapped, crystal creates a satisfying bell-like ringing sound. The lead content in the material allows the sounds to be slightly prolonged.
فواید
Glass: Glass tableware is a great option for everyday use because it is made thick and durable. It can be put in the dishwasher for easy cleanup and has a reinforced rim to prevent chips and cracks.
Crystal: Crystal glass refracts light beautifully, glinting light into rainbows. This makes it an excellent choice for cups, bowls, vases, champagne flutes, chandeliers, and ornaments. It can also be molded thin, which means that wine glasses can have a thin rim, providing an uninterrupted flow of wine. Crystal is also popular at weddings because of the ringing noise it makes when glasses are clinked.
