Seger|ˈzeɪgə(r)|
[The name of Hermann August Seger (1839–93), German ceramics technologist.]
Seger (also seger) cone: each of a series of small numbered cones or pyramids made of different mixtures of refractory material and flux so that they melt at different known temperatures, used to indicate the temperature inside kilns, etc.
[1890Jrnl. Iron & Steel Inst. II. 680 Professor Seger's ‘normal’ clay pyramids..should find extended application. 1894Ibid. XLV. 432 Le Chatelier's pyrometer was used.., as Seger's cones did not appear to exactly meet all requirements.] 1895Ibid. XLVII. 304 These Seger cones give the temperatures with quite sufficient accuracy. 1931G. W. Tyrrell Volcanoes iv. 115 He used a stout iron pipe within which seger cones were fastened at regular intervals, and thrust it into the lava as far as he could. 1964H. Hodges Artifacts i. 40 There are several series of pyrometric cones of which the Seger cones are, perhaps, the most commonly used. 1971Materials & Technol. II. v. 271 The plaque..is heated above 1000°C at about 10°C per minute, and the end point is taken as the temperature (as indicated by the condition of the Seger cones) at which the tip of the test cone is on a level with the base. |
