Asians and Europeans have a long history of using tin. Tin mugs have traditionally been used in Europe to enhance the taste of beer and liquor, for instance. The Japanese make tin cups for sake. In some parts of China, brides’ families would place elaborate orders at the tinsmith’s for their dowries. In bygone times, tin was a precious metal on a par with silver and gold. Vessels and containers made of tin were a prized luxury. In more recent times, advances in mining have brought tin to market at prices that don’t break the bank. How to care for tinware: Clean your tin using a sponge and soap or detergent. Do not use scrub sponges or steel wool. Tin is a soft metal. Rough or abrasive cleaning instruments may leave scratches. • Avoid storing tinware at temperatures under -5 ℃ (23 ℉) — such as in the freezer — or over 140℃ (284 ℉). • Don’t let your tin come in contact with highly acidic or highly alkaline substances. The tin may oxidise and change in colour. • To restore oxidised tinware to its original colour, rub it with a silver polishing cloth or a linen cloth, or crumple up some copy paper and go over the tin with the crinkled edges. • Tin will oxidise slightly if left sitting for long periods of time. This is totally normal and doesn't impair the utility of the tin, but you can prevent this by storing your tin in a cupboard or a box. Oxidised tin can be restored as described above.
