[导读]有2种笨方法确定蓝宝石玻璃和矿物质玻璃
How to Differentiate a Sapphire Crystal from a Mineral Crystal Oct 03,2005 -06:26 PM There are two fool-proof tests to differentiate a sapphire crystal from a mineral crystal:有2种笨方法确定蓝宝石玻璃和矿物质玻璃
怎样确定蓝宝石玻璃和矿物质玻璃
1) the colour test -look at the edge of the crystal.A sapphire crystal will have a pinkish hue,a mineral crystal will have a greenish hue.颜色:蓝宝石玻璃发粉色,矿物质玻璃发绿色
 
2) the water test -place large drops of water on the crystal,then tilt the watch and watch the water slide off.On the sapphire crystal,water will easily slide off -leaving small well-formed round globules of water on the surface.On the mineral crystal -most of the water will"stick"to the crystal and the drops of water will spread across the surface of the crystal to form a non-uniform"puddle"instead of sliding off.水测法:放一大滴水在表镜上,倾斜让水流下。蓝宝石玻璃上的水流的很快,水滴不变型,无残留。矿物质玻璃上的水滴发“粘”,留在表镜上的水没"型"。
 
Try both tests on watches you know have sapphire crystals or mineral crystals and the results will become immediately apparent to you.Test number 1 doesn't always work if the edge of the crystal is not a clear polished finish(instead an opaque powder finish) -and can be confusing before a comparison test is performed.2种方法都试验一下,因为第1种不是很灵,表镜的边缘有时被抛光,打毛处理过。
