Here  is  a  refining  tip  from  @jen_surine  -  βThis  tip  is  one  I  picked  up  from  @metalsmithsociety  a  while  back,  but  it  is  such  a  great  one,  I  had  to  share.  
Running  my  tumbler  water  through  a  coffee  filter  catches  particles  of  silver  and  gold.  It  literally  prevents  me  from  pouring  money  down  the  drain.  Before  I  started  doing  this  I  honestly  had  no  idea  how  much  gold  and  silver  the  coffee  filter  would  be  collecting!
Once  the  filter  gets  gunked  up  I  throw  it  in  a  bag  that  I  send  to  my  precious  metals  refiner,  along  with  dust  from  my  buffing  machine,  floor  sweeps,  and  dirty  rags  I  I  use  around  the  studio.  
It  all  turns  into  money  again.  
Did  you  see  all  that  glittery  gold  and  silver  caught  in  the  filter?  πβ  thanks  for  letting  me  share  Jen!  So  helpful  to  see!  π  #refininggold  #refiningsilver  #recycledmetals  #jewelrymaking
