es: SEGER CONOS
Seger cones are for measuring heat in kilns and were made and invented in Germany in 1886 by Dr. Hermann Seger. Their shape is an elongated triangle, coded by numbers and colors. The color is to help distinguish the different degrees, as there are many and so small that it is difficult to read the indented stamp. There are two types; Mini Cones which are placed in the sensing rod and when the kiln arrives at correct heat they bend, cutting off the electricity and Standard Cones which are for testing the heat in different parts of the kiln.
