Q. How is a magic pane made?

The ink of the pen is stored in a polyester reservoir. Porous ceramics or synthetic fibers are typically heavily compressed to create the "felt" utilized for the tip. As solvents xylol and toluol were employed for the dye and they are still used for the indelible ink in permanent markers. The nib traditionally made of firm felt and the cap that keeps the marker from drying out are located in the upper portion of the marker. Their toxicity has led to their replacement in several marker formulations with less important chemicals.
