According to the temperature employed in the pyrometric
tests, it was possible to observe stability temperatures below 1300[degrees]C and up to 1600[degrees]C and softening temperatures and vitrification from approximately 1600[degrees]C and above, as is shown in Figure 7.
Beginning with wet stoneware scrap clay combined with sawdust, perlite and nylon fibre, Gordon pressed the mixture onto a bed of salt crystals, copper shavings, rust scale, glass fragments, pyrometric
cones, small pottery shards and metallic found objects.
measurements detect the surface temperature and by the help of simulations it is possible to draw conclusions regarding the tensions in the glass.
cone equivalent testing determines the refractory value of a coating.
The Orton Ceramic Foundation has been producing high quality Pyrometric
Cones for the worldwide ceramic community since 1896.
It is not unusual to have several different clay body formulas for specific pyrometric
cone ranges such as cone 9 (2300[degrees]F), cone 6 (2232[degrees]F) and cone 04 (1945[degrees]F).
THE CONES KNOW Use pyrometric
cones to monitor when you have reached temperature.
The functionality of such a system could be proved by a pyrometric
temperature control in the TIG-overlay welding procedure and in laser transmission beam welding.
The tests discussed in the presentation were core degradation, Baume, weight per gallon, viscosity, solids content, coating deposit, penetration and permeability, Pyrometric
Cone Equivalent, biological growth and pH.
Comments on efficient air and heat flow, and the use of pyrometric
cones is of value in this worthwhile video.
