The oblique dip pen was designed for writing the pointed pen styles of the mid 19th to the early 20th century such as Spencerian Script, although oblique pen holders can be used for earlier styles of pointed penmanship such as the copperplate scripts of the 18th and 19th centuries. As the name suggests, the nib holder holds the nib at an ...
Dip pen nanolithography (DPN) is a scanning probe lithography technique where an atomic force microscope (AFM) tip is used to directly create patterns on a substrate. [1] It can be done on a range of substances with a variety of inks. A common example of this technique is exemplified by the use of alkane thiolates to imprint onto a gold surface ...
A luxury pen. A pen is a common writing instrument that applies ink to a surface, usually paper, for writing or drawing. [1] Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity that had to be periodically recharged by dipping the tip of the pen into an inkwell.
Dip-pen scanning probe lithography (dp-SPL) or dip-pen nanolithography (DPN) is a scanning probe lithography technique based on diffusion, where the tip is employed to create patterns on a range of substances by deposition of a variety of liquid inks.

Quill and a parchment. A quill is a writing tool made from a moulted flight feather (preferably a primary wing-feather) of a large bird.Quills were used for writing with ink before the invention of the dip pen/metal-nibbed pen, the fountain pen, and, eventually, the ballpoint pen.
The firm was founded in Manchester as James Perry and Co. in 1824, but later moved to London, where they made and sold pens and pen-holders, pencils, elastic bands and ink, and dealt in stationers' supplies. [1] From 1829 all of Perry's pens were made by Josiah Mason, which was considered by the time as the finest pens manufacturer. [2]
A fountain pen is a writing instrument that uses a metal nib to apply water-based ink, or special pigment ink—suitable for fountain pens—to paper.It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use.
