Abstract: A method of producing and using an artists chalk from dry copier toner is disclosed. The method includes the steps of providing a holder having a cavity for holding the toner, the cavity having a shape which, at least approximately, defines the shape of the finished chalk; and heating the toner at a temperature high enough and for a period long enough to sinter the toner into a chalk. Pressure is not applied to the toner particles. The temperature is in the range of, approximately, 150° F. to 220° F., and the time is in the range of, approximately, 3 to 60 minutes. The holder typically includes a paper tube which forms part of the finished chalk. Typically, the temperature is in the range of 180° F. to 185° F., and the time is in the range of 7 to 11 minutes. For harder chalks higher temperatures and shorter times are used. For softer chalks, lower temperatures and longer times are used.
