[modeleng] Tanalising

Hi All,

    I recently bought some tanalised wood.   I screwed and glued (PVA 
glue) a couple of pieces together.   Of course some of the glue oozed 
out of the join.   I scraped this up using a steel bladed scraper.   The 
scraper became nicely copper plated!

    The only time I have seen steel become copper plated like this is 
when it comes into contact with copper sulphate.   Is that what 
tanalising is - just soaking the wood in copper sulphate?

    I am sure someone here on this list will know.

    The wood was being used on the workshop - model engineering content!


       Cheers,


          Roger Mason,  in St. Agnes.
