	== ~~Remove~~ image ==		== Removing the image ==
	* ~~Wash~~ the stone with ~~terpetine~~ to remove the ink on the image		* grind the stone with pumice to remove the ink on the image
	* grind two stones together with sand and water between the stones		* grind two stones together with sand and water between the stones in an 8-shaped pattern. The mixture of water and sand is when the top stone rolls over the sand particles but does not touch the bottom stone. I.e., there needs to be a layer of sand that covers the full bottom stone and enough water to make the grinding go smoothly. Don't put pressure on the top stone, it's weight should do the work.
	* grind ~~til~~ you don’t see the image ~~any moreGrind a bevel on~~ the stone with the stone file.		* grind until you don’t see the image anymore. Bevel the edges of the stone with the stone file.

	== ~~Grinding a~~ stone ==		== Polishing the stone ==
	* grind the stone with ~~a glass or steel muller an abrasive we use~~ carborundum ~~and water start~~ with ~~rough grit carborundum then~~ medium ~~carborundum~~ and fine carborundum		* Wash both stones so there are no stone or sand particles anymore
			* Start off with the roughest grain carborundum powder and grind the stone again in the same way as with the sand do this for 5 to 10 minutes
			* Wash both stones so there are no carborundum particles anymore
			* Repeat this step with the medium and fine carborundum. Make sure that before the switch, the stone is clear of carborundum

	~~== Make a image on a~~ stone ==		* grind the stone with a glass or steel levigator and the finest carborundum and water. Use a pattern that covers the whole stone equally. Don't put any pressure on the levigator.
	* draw with ~~Lithographic crayon~~ or ~~Lithographic pencil thous contain greasepaint with lithographic tusche you can~~ water the ~~ink down to get grey tones~~

	== ~~Eching~~ a stone ==		== Make a image on the stone ==
	* use cotton wool to apply talcum powder over the image pour a mixture of ~~gom arabic~~ with nitric acid on a ~~non with~~ part of the stone and move it over the image ~~with~~ a ~~squeezed sponge end with a thin~~ layer ~~over the stone~~		* draw with one of the special materials for stone lithography. Lithographic crayon, Lithographic pencil, Tusche, or Lithographic ink. Make sure to keep the edges (+/- 5cm)of your stone free from drawing. The edges won't be printed.
			== Etching the stone ==
			* prepare the etching fluid. This is a mixture of gum Arabic with nitric acid. If you are not sure how to do this ask one of the staff. Nitric acid is dangerous!
			* use cotton wool to apply talcum powder over the image.
			* pour the mixture of gum Arabic with nitric acid on a white part of the stone and use a damp sponge to move it over the image. Keep moving this around for a minute or two. Then thinner the layer of gum as much as possible.
	* wait at least 12 hours		* wait at least 12 hours

	== ~~Wash and rolling up~~ ==		== Washing the stone ==
	* wash of the acid ~~gom mix~~ with water and sponge		* wash off the acid gum Arabic with water and a sponge
	* dry the stone with a ~~lithographers~~ fan.		* dry the stone with a lithographer's fan.
	* apply plain gum on the stone with a ~~squeezed~~ sponge ~~end with a thin~~ layer ~~over~~ the ~~stone~~		* apply plain gum on the stone with a damp sponge and make the layer thin
	* ~~wash out~~ the drawing ~~materials~~ with ~~pure~~ turpentine ‘dry wash’ the surface of the stone is protected by the gum ~~arabic~~.		* Dry the gum Arabic
	* wash of the gom with a good amount of water keep the stone wet with sponge		* Start removing the drawing with turpentine. This is called the ‘dry wash’ the surface of the stone is protected by the gum Arabic.
	* ~~roll up~~ the ~~image~~ with ~~not drying black ink (pen inkt)repeat till you see~~ the ~~image again~~.		* wash off the gom with a good amount of water and keep the stone wet with a sponge
			* remove the rest of the drawing with turpentine. This is called the ‘wet wash’ the surface of the stone is protected by the water.

	== ~~do a second etching~~ ==		== Rolling up the stone ==
	* use ~~cotton wool to apply Rosin dust powder over the image~~		* Refresh your washing water and make sure the sponge you use from now on has no turpentine in it
	* ~~use cotton wool~~ to ~~apply talcum powder over the image~~		* Use the sponge to moisten your stone. It is important that the stone is completely moist every time it encounters the ink roller. It should not be wet. Too much water will prevent the ink from the roller from attaching itself to the greasy parts of your stone.
	* pour a mixture of gom arabic with nitric acid on a non with part of the stone ~~and move~~ it ~~over~~ the ~~image with a squeezed sponge end with a thin layer over~~ the stone.		* roll up the image with not drying ink (pen ink) and repeat till you see the image again as you have drawn it. Be sure to moisten your stone all the time.
	* ~~Wait for a hour~~.

	* ~~Wash~~ and ~~rolling up~~		== Second etching ==
			* Dry the stone
			* use cotton wool to apply Rosin dust powder over the image
			* use cotton wool to apply talcum powder over the image
			* pour the mixture of gum Arabic with nitric acid (usually stronger than the first consult a teacher for details) on a white part of the stone and use a damp sponge to move it over the image. Keep moving this around for a minute or two. Then thinner the layer of gum as much as possible.
			* Wait for 5 to 10 minutes. Time to have a coffee or thee break before the printing parts starts.
