TWO THOl'SAND DEGREES
1'NDKR THE MICROSCOPE by J. H. Welch of the Building Research Station
Cement, glass, bricks, steel. They are all made at high temperatures. But how can we find out exactly what is happening at 2,000° Centigrade? Whipping out samples and cooling them rapidly is one way, but it is now possible to observe high-temperature changes directly in the high-temperature microscope. The speaker describes the instrument and some of the things that can be done with it.
