Orton packages small cones in pairs to minimize breakage during shipping. This video shows how to Separate a pair of conjoined Small Orton Cones. Watch the PRODUCT VIDEO below to learn how to separate them. Pyrometric cones measure heat-work (the effect of time and temperature). They are slender pyramids made from about 100 carefully controlled compositions. Each cone number is unique in measuring temperature within a small temperature range (less than 30°C). Cones measure the amount of heat absorbed over time. As the cone nears its maturing range, it softens and the tip begins to bend, drawn down by the influence of gravity.Junior cones are designed to be used in a KilnSitter. Warning! Do not view cones above earthenware temperature with the naked eye as this may cause cataracts. View through welders goggles - sunglasses are not suitable as they filter out UV, but not the infra-red, which is the damaging wavelength in this case!
