There are no long term effects of etching the teeth before sealant application. The etchant is a strong acid that dissolves the matrix material between the enamel rods that make up the tooth. It is rinsed off within seconds and leaves the tooth with a frosty appearance when dried. The nature of a resin dental sealant is that it requires a mechanical bond with the tooth, this mechanical bond is achieved between the sealant material and the enamel rods. In the case the tooth was "over etched" that is to say the sealant material is not covering the entire etched surface of the tooth, the minerals in the saliva, and topical fluoride rebuild that area of the tooth to make it as sound as it was before the procedure.

There are none. The purpose for the etching step is to create a rough surface for the composite material to hook into as it hardens. Think of it as a velcro system!
Etching is a process to produce semiconductor devices. It is also used in printing. Wet etching and Dry etching are possible.
An etching on paper is a print made from a metal plate, called an etching.

Drawing with crayons is not etching. You do not dig into anything with crayons. To create a crayon etching, you would need to use the crayon to indent something.

Glass etching pastes or cremes contain fluoride. The most common are sodium fluoride and hydrogen fluoride. This does not 'etch' the glass, it causes fluoridation which looks like etching.
The difference between the two intaglio processes of etching and engraving is the use of acid. Engraving is a form of dry point and etching uses acid.
If the etching is one of a kind, I recomend looking for the name of the artist on the etching. If there is a name, you can look up the artist and get a general idea of what a piece of his/her art is worth. If there are more than one sculpture/etching of this same theme. Try to find the price or value of the other.
The basic stages involved in making a pcb (printed circuit board ) are: Designing the traces on paper or an autocad style computer application. Using a transfer or mask to apply a resist to a copper clad board Spraying or putting the copper clad board into an etching bath of acid. The etching bath removes the copper that was not protected by the resist. Washing the etching solution off to stop the process. Removing the resist that protected the copper.
