Renovating An excellent method of rendering tim- 



Mahogany. ber impervious to fire is to cover its sur- 



face with a solution of silicate of soda. 

 When wood treated in this way is exposed to a fierce flame, the 

 heat draws the salt contained in the solution to the exterior of 

 the timber on which it forms a glazed coating, after having been 

 melted by action of the fire. The solution should be generally 

 adopted as a wash for woodwork in houses, as it effectually re- 

 tards the action of the flame which the resinous nature of the 

 deal commonly used in building is too liable to promote- 



To renovate mahogany. Dissolve four ounces of best white 

 wax in 8 ounces of turpentine and 6 ounces of water in a glue 

 kettle over the fire, and while hot add an ounce of ammonia. 

 Stir well together whilst cooling. Remove all dust from the ar- 

 ticles ; then apply with old pieces of clean flannel and polish. 

 Before renovating, if there are dents in the furniture, cover the 

 places with a damp rag, and iron with red-hot iron and then 

 polish with the following solution : Equal parts of linseed oil, 

 vinegar and water. Put them in a bottle and shake well to- 

 gether; apply with a piece of flannel, and polish with soft cloth.
