What is the technique for gram staining test?

the gram staining procedure involves four basic steps; 1.the smear is first flooded wit the primary stain crystal violet dye.in this case the primary stain is the first dye applied in any multicelled staining procedure and it stains all the cells. 2.the smear is rinsed with water to remove any excess crystal violet and then its flooded wit a dilute solution of iodine called grams iodine.iodine acts as a mordant.i.e. the substance that increases the interaction and affinity of cellular components for a dye.this is done so that the cells can stain more strongly. in this case the iodine complex thereby decreases the solubility of the dye within the cells 3.the stained smear is rinsed again and then 95% alcohol or a mixture of alcohol and acetol is briefly added.this solvent acts as decolorizing agents and they readily remove the dye iodine complex from gram negative but not from gram positive bacteria. 4.a counter stain is then applied to import a contrasting color to the now colorless gram negative bacteria.for this purpose,the red dye safrannin is used.this dye stains gram negative as well as gram positive bacteria but because the gram positive are already stained purple,it impacts little difference
