I write mostly about public schools, but private schools have their own methods and rituals that affect many families. At this time of year, for instance, parents looking for a good private school often find themselves in trouble. They have applied to a school they had their heart set on. They have been rejected. Actually, it is their child who has been turned down, but you know what I mean. This can create panic.
Different Types of Luster. The Earth has so many minerals in different categories. Since luster is a property of minerals, luster also varies widely, so there are many different types. Mineralogists first divide the types of luster into two categories: metallic and nonmetallic.
Solder (also spelled soder by some) is a metallic compound that when heated, and subsequently cooled, fuses 2 pieces of metal together. Generally solder is silver in tone, but not always made of actual silver. Ok, anywho: older tea sets are made of pure silver. The solder they used to fuse the handles of cups, or the spout of the tea pot to the base is actually silver solder, made from silver, not just silver colored.
