(This sand is an unsieved natural quarried sand and may contain stone inclusions. Prior to use it needs sieving to remove inclusions and break up sand lumps as well as the moisture content adjusting to suit, any sand lumps can be crushed through the sieve with a moulders trowel. In the worst case senario you may get 10% inclusions.)
Using Bromsgrove Greensand/ Green Sand
Green sand is not green in color, but "green" in the sense that it is used in a wet state (akin to green wood). Bromsgrove sand has all the natural qualities required of a high quality moulding sand.Through use the condition of the sand will improve and will eventually blacken. After considerable long term use a new bag should be mixed in to recondition the sand and replace any burnt out clay deposits.
The sand must not be too wet or it becomes sticky, nor should it be too dry as it will not form correctly and crumble. Remember to do the hand squeeze test, it should easily mould to shape and not stick to your hand but cleanly break when snapped without crumbling.
If working with cast iron you can add 3 to 5% of coal dust which will help gases escape and produces a smoother casting.
Follow appropriate health and safety procedures.
