In making containers sand is added to clay______．

Clay l3an often be found________．

The article is most probably from_______．

完成下列各题

D

Clay is important because it is used to make containers of all kinds．Workers add water to soften clay．This makes it．easier to form. into shapes by machine．Then it is heated to a very high temperature．The result is a container that．will last for many years．

In many countries，clay was formed from volcanoes(火山>．This．kind of clay usually contains many minerals(矿物质)．So the fires to make containers from volcanic clay must be hotter that those used for non—volcanic clay．The fires may be as hot，as 1400℃．The high temperature should not be reached too fast SO that the containers can be dried slowly．You can add some materials to clay to gain desired results．For example，you can add sand to prevent tiny breaks or lines from forming on the surface of the final product．But you should not use sand from the coasts of oceans．Instead，you should use sand from rivers or other areas．

Clay often exists in fields covered with some water．The clay will be found about one meter below the ground．．River banks often also have clay about one meter or less under the surface．Clay is very shiny when it is wet．You can also take some of the material and add enough water to it．Then press it in your．hands until it is about the size of an egg．It is probably clay if it holds together when you stop pressing．

What’s the difference between volcanic clay and non-volcanic day?
