			Hey, all; 
		
		
		
		
		
		
		
	I have that project jambiya just about ready for the etching stage, and was wondering what proportions to use when mixing the etch. I have both ferric chloride and copper sulfate in powder form, and need to know what ratio to use: how many ounces of powder to add to say 8 oz. of water to mix the proper strength? Thanks!  |
