es: SEGER CONOS
Seger cones are for measuring heat in kilns and were invented and made in Germany in 1886 by Dr. Hermann Seger. Their shape is an elongated triangle and they are 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 which bend and cut off the electricity when the kiln arrives at correct heat and Standard Cones which are for testing the heat in different parts of the kiln.
