Journey with Art Clay Silver 純銀黏土的燒成原理

Making Process 製作銀黏土的基本過程

 

Sterling Silver 925 VS Pure Silver 999
925 標準銀 與 999 千足銀

Pure silver, also referred to as fine silver, has actual silver content of 99.9%. Because of its high purity, fine silver is too soft to use in jewelry making and is often mixed with other metals to make it harder.

Sterling silver is an alloy created when copper is added to pure silver in order to make the resulting compound more durable and less soft.

Usually, sterling silver has a purity of 92.5%, meaning that 7.5% of the alloy is made of copper or another metal (usually nickel or zinc).

純銀，又稱千足銀，其含量有高達99.9%的銀成份，因為它的純度極高，所以也比較軟，多數會混與其他金屬來增加硬度。以銀黏土所製的銀飾品，多數只要不故意用外力加以破壞，也是有相當的硬度的。

標準銀，是一種與銅做結合的合成金屬，以致增加它的硬度與耐度；通常，標準銀是由92.5%的銀和7.5%的銅所製成的，但有時也會混合其他金屬，如鎳或錫。

Pure Silver, Sterling Silver, and Tarnishing
純銀、標準銀與氧化

Although sterling silver is more durable than pure silver, the additional metals in the alloy make sterling silver more prone to tarnishing.

This happens because the copper, nickel, zinc or other mixtures in sterling silver may react with oxygen and other elements in the air.

雖然標準銀比千足銀來得強韌，但是其他添加的合金金屬，反而導致標準銀更加容易氧化，會發生這個情形多數是銅、鎳、錫或其他的混合金屬會與空氣中的氧氣或其他外來元素產生化學變化。

Sterling Silver and Plating
標準銀與鍍銀

Often, sterling silver items are plated with a thin layer of pure silver to improve the shine of the piece.

大多數的標準銀會在表面做一層鍍銀來增加表面的光亮度。

純銀黏土在燒成後是成為99.9%的千足銀喔！
