Mitä eroa on lasilla ja kristallilla?
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.
Kristalli vs lasi
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.
Mikä on lasi?
Lasi on läpinäkyvä materiaali, joka voidaan sulattaa ja muotoilla kiinteisiin muotoihin. Se on valmistettu hiekasta, soodatuhkasta ja kalkkikivestä, mutta muita mineraaleja, kuten piidioksidia ja bariumia, voidaan lisätä manipuloimaan sen väriä, kestävyyttä ja paksuutta.
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.
Mikä on Crystal?
Kristallilasi on läpinäkyvä materiaali, joka on valmistettu samoista ainesosista kuin lasi, mutta siihen on lisätty lyijy-oksidia tai metalli-oksidia. Lisäaineet saavat kristallin säilyttämään eheytensä myös leikattaessa tai puhallettaessa. Kristallilasiin lisätyt ainesosat tekevät materiaalista hieman huokoisen, mikä antaa sille kyvyn taittaa valoa loistavasti. Tämä tarkoittaa kuitenkin myös sitä, että materiaali ei ole astianpesukoneen kestävää.
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.
Erot lasin ja kristallin välillä
Sekä lasi että kristalli valmistetaan kuumentamalla niitä uunissa, kunnes ne sulavat. Sitten ne puhalletaan lasipuhaltimella ja muotoillaan halutuiksi malleiksi. Näillä kahdella materiaalilla on kuitenkin erilaisia eroja niiden kemiallisesta koostumuksesta ja painosta siihen, miten ne taittavat valoa ja kaikuvat ääntä. Tarkastellaan tarkasti niiden eroja alla selvittääksemme, miksi kristallin hinta on korkeampi.
Ulkonäkö erot
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.
Painoerot
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.
Paksuuserot
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.
Leikkaa eroja
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.
Taittumiserot
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.
Äänierot
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.
Edut
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.
