Gray chalks are not useful in grounds they develop ugly dark spots when touched by oil. French chalk was a type of solid talc bar used by tailors for marking cloth , by cleaners for removing Fat grease from cloth and as a dry lubricant in its powdered form. French chalk has also historically been used in the repair of punctured inner tubes of pneumatic tire s, such as are found on bicycle s. A block of French chalk is typically included in proprietary puncture repair kits, which may include some means of generating a fine powder from the block, for example a small file or a roughened area on the metal case in which the repair kit may have been supplied. The French chalk prevents the repair from sticking to other parts of the tire.
