		The salt, ferric chloride, has none of the disadvantages associated with the other two etching solutions: it does not produce dangerous fumes, is odourless and, though corrosive, is not absorbed through the skin.
		Ferric chloride solutions in water are strongly acidic but in their reaction with copper no significant fumes or gases are produced.
		Ferric chloride can be obtained either as a solid (not recommended as it can give off highly toxic hydrogen chloride fumes when mixed with water) or in liquid form which is usually supplied in a strength of 45° Baume.

	Ferric and acid complex - Patent 7034172
		A ferric and acid complex as set forth in claim 2 wherein said ferric salt is selected from the group of ferric sulfate, ferric carbonate, ferric chloride, ferric nitrate, ferric bromide, ferric citrate, ferric glycolate, hydrates of said ferric salts, and combinations thereof.
		Although the ferric and acid complex may be stored and packaged in the solvent, it is to be appreciated that the ferric and acid complex may be separated from the solvent into a solid form, such as a powder.
		Ferric and acid complexes of the subject invention are prepared by first charging solvent into a 1 liter vessel, which is a flask, at room temperature of about 77° F. The chelant is then charged into the vessel, along with a portion of the base until the pH value within the vessel is about 4.

	Foodstuffs containing a cereal ingredient and ferric EDTA - Patent 5534275
		The ferric EDTA component of the R-T-E cereal of example 1 was replaced with reduced iron, ferrous fumarate, and ferrous sulfate, and the samples were tested for three characteristics: 1) color or brightness; 2) metallic offtaste; and 3) oxidative stability.
		This example establishes that ferric EDTA is superior in bioavailability to reduced iron which is commonly used for iron fortification in breakfast cereals.
		Ferric EDTA can also be combined with an additional iron source, i.e., reduced iron, in different types of cereal ingredients.

	33699. Etching at 40 degrees Centigrade with Ferric Chloride on 304 SS [Australia]
		Yes, it is the effectiveness of the etching which we are worried about, the evidence of a "scum" in the ferric chloride is an observation that is made when "etch rate" is diminishing.
		Ferric for very little etched area and we would have thought to acheive much more etching from such volumes, hence my question as to whether the temperature may have had an impact.
		The ferric chloride solution will dissolve the nickel and chromium as well, so if you want to be totally technical, these have to be taken into account in the overall reaction.
