Metallic Sterling silver is the
traditional material from which good quality cutlery is made. Historically, silver had the advantage over other metals of being less chemically reactive. Chemical reactions between certain foods and the cutlery metal can lead to unpleasant tastes.
Gold is even less reactive than silver, but the use of gold cutlery was confined to the exceptionally wealthy, such as monarchs.
Steel was always used for more utilitarian knives, and
pewter was used for some cheaper items, especially spoons. From the 19th century,
electroplated nickel silver (EPNS) was used as a cheaper substitute for sterling silver. In 1913, the British metallurgist
Harry Brearley discovered
stainless steel by chance, bringing affordable cutlery to the masses. This metal has come to be the predominant one used in cutlery. An alternative is
melchior, corrosion-resistant
nickel and
copper alloy, which can also sometimes contain manganese and nickel-iron.
Titanium has also been used to make cutlery for its lower thermal conductivity and considerable weight savings compared to steel, with uses in camping.
Disposable cutlery Plastic Plastic cutlery is made for
disposable use, and is frequently used outdoors for
camping,
excursions, and
barbecues for instance. Introduced for
convenience purposes — being lightweight and needing little clean-up after the meal —
disposable cutlery made of
plastic has become a huge worldwide market. These products have become essential for the
catering industry,
fast food and
take-away outlets as well as being provided with
airline meals where metal cutlery is banned, along with other
disposable tableware — paper plates, plastic table covers,
disposable cups,
paper napkins, etc. The products are emblematic of
throw-away societies and the cause of millions of tons of non-biodegradable
plastic waste. Plastic cutlery has been banned in Australia, but there remain public calls for its return. The European Union has banned such plastic products from 3 July 2021 as part of the
European Plastics Strategy. Bans are also planned in the UK and Canada. Also, plastic is used for some young children's cutlery that is often thicker and more durable than disposable plastic cutlery, often encountered in the early years of primary schools.
Wooden As an eco-friendly
biodegradable alternative to non-degradable plastic,
wooden disposable cutlery is gaining popularity. Bamboo (although not a wood) and maple are popular choices. Some manufacturers coat their products in food-safe plant oils, waxes, and lemon juice for a longer shelf life making these safe for human use. Cutlery is then cured for a few days before leaving the manufacturing plant.
Edible Edible cutlery is made from dried grains. These are made primarily with rice, millet, or wheat. Since rice cultivation needs a lot of water, manufacturers market millet based products as more environment friendly. The
batter is baked in moulds which hardens it. Some manufacturers offer an option of flavoured cutlery. Edible cutlery decomposes in about a week if disposed. ==Manufacturing centres==
