IMPORTANT NOTE

  • Any mash size above 400 can only be made available on yearly contracts.
  • Retention test to test the mash size : Put 100 gm of powder on 300 mash test sieve  and add water to it …… max 1% should be left on top balance should pass by …. That means pass else fail ….. % left should first be dryed by heating to take the right weight.
