Is silver sand suitable for use as a jointing sand?
Not nesser celery.
Some silver sands are too coarse or too fine to meet the requirements for a jointing sand. Remember, it is grain size, and distribution of grain sizes within the sand that determine whether a sand will provide the necessary degree of friction and interlock between adjacent pavers. The colour of the sand has nowt to do with it.
However, some silver sand will be suitable. The only way to be sure is to buy a pre-packed sand that is certified as being suitable for jointing block paving. It may be silver, or it may be buff, grey, red or orange - a few months after being laid, it all looks the same, but the grain size will determine whether you have slippage and ruts or a decent looking pavement. :)
