No! Clay’s sold at craft stores are (98% of the time) polymer clays. These can be fired in a toaster oven, but be sure to read directions on any clay that you buy. Even at a super low fire temperature, a kiln still reaches over 1000 degrees F.
A cone is a way to measure the temperature in your kiln. Many older kilns will have a kiln sitter, which requires a cone to be placed inside the mechanism and will bend when the cone reaches temperature, it will shut off your kiln. Most newer kilns are run by a computer system and a thermocouple. This essentially takes away the need for a cone. However, many potters choose to still place a cone in their kiln to just double check the accuracy of the kiln computer.
