Hello All -

    I worked for a small jewelry manufacturer many years ago and spent
    some time troubleshooting our investment/casting issues.  

    We daringly tried an experiment on some injection waxes that
    produced amazingly cleaner castings. 

    After the wax models/sprues are added to the rubber base try
    spraying the whole thing with a spray bottle mixture of room temp.
    water and about 1/2 teaspoon of mild dishwashing liquid.  Let it
    stand on the waxes for about a minute and then rinse off under
    gently running tepid water.  Use an air-gun (low pressure) to blow
    the excess water off and dry the tree... then invest as usual. Yes,
    you'll need an airline in your studio. 

    This step will remove hand oils, lint, small particles of wax dust
    and any other surface dirt that may be stuck on the waxes and
    sprues.  

    If you already do this process, good for you !  It does make a
    difference. 

    Thanks to some great people that I worked with, this step gave us
    better surface quality on our castings ! 

Ciao,
