314. STAINING WOOD. 



wet, brush it over with alum-water made in the 

 proportion of two ounces of alum to a quart of 

 water. 



For a less bright red, dissolve an ounce of dra- 

 gon's blood in a pint of spirits of wine, and brush 

 over the wood with the tincture till the stain appear 

 to be as strong as is desired ; but this is, in fact, 

 rather lacquering than staining. 



For a pink or rose red, add to a gallon of the 

 above infusion of Brazil wood two additional 

 ounces of the pearl-ashes, and use it as was before 

 directed : but it is necessary, in this case, to brush 

 the wood over with the alum-water. By increasing 

 the proportion of pearl-ashes, the red may be 

 rendered yet paler ; but it is proper, when more 

 than this quantity is added, to make the alum-water 

 stronger. 



To stain Wood Blue. 



Wood may be stained blue by means either of 

 copper or indigo. 



The method of staining blue with copper is as 

 follows : Make a solution of copper in aqua fortis, 

 and brush it while hot several times over the 

 wood j then make a solution of pearl-ashes in 

 the proportion of two ounces to a pint of water, 

 and brush it hot over the wood stained with the 

 solution of copper, till it be of a perfectly blue 

 colour. 



To stain Wood Green. 



Dissolve verdigrease in vinegar, or crystals of 

 verdigrease in water, and with the hot solution 

 brush over the wood till it be duly stained.
