3[i' STAINING WOOD. 



wet, bi'usli 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 slam Wood Blue. 



W-ood may be stained blue by means either of 

 copper or indigo. 



The method of staining blue with copper is as 

 ibllows : Make a solution of copper in aqua fortis, 

 and brush it w^iile hot several times over the 

 wood ; then make a solution of pearl-ashes in 

 the })ro])ortion 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 slain Wood Green. 



Dissolve verdigrease in vinegar, or crystals of 

 verdigrease in water, and with the hot solution 

 brusji over llie wood till il, ])c duly stained.
