Step 4: Pour Liquid rubber compound slowly and gently over the milled object make sure that it should raise little above the height of object, After pouring the compound into mold as shown in    fig 7.

Step 5: Keep object of Poured liquid rubber compound at room temperature for 4 hours, remove mold from object after set time is over, and Remove the solid rubber mold cavity gently from the wax impression

Step 6: Mold cavity is ready for pouring of plastic or Instamold or Dry stone powder, in this process Instamold powder is used.

Step 7:Mix the powder gently with the water, in such a way that, first take water in a cup add 1/3rd of powder stir it again repeatedly add powder in to the water until it converted into slurry. Never add water in the powder, add powder into the water.

Step 8:Now pour the slurry gently into the mold cavity until the mold cavity is fully filled, and Keep the mold cavity for curing up to 1-1:50hr or until it becomes solid.
