    There have been some excellent  posts already submitted regarding
    making a flowerpot burnout kiln.  I just want  to add a few
    suggestions. It is a smelly process, so unless you have no other
    alternative try to burn outside or in your  garage. It can be done
    inside, on your kitchen range, but you should have the hood fan on
    to assist with the exhaust of the fumes.  This is a noisy nuisance,
    will smell horribly,and  the soot will  cover your cabinets. 

    Be sure to elevate your flask.  A small piece of firebrick (about 2
    inches square)  should be  placed under  one rim of the flask , 
    tilting it slightly. Place it so  the the dish side of the flask is 
    downwards so that the wax can flow out., You can burn out more than
    one flask at a time by placing them around the disk of firebrick.  

    The amount of time needed for the burnout will vary depending on the
    heat output of your range,and the type of wax used. If I remember
    correctly  I used to allow 4 hours.  You can judge whether the
    burnout is complete by the chalk white appearance of the investment.
    Also, there should be a red glow radiating in the dish part of  the
    investment, and the little  sprue chanels will glow  sort of orange
    red.   Examine them in a dim light as they will not show up clearly
    in a bright light. 

    When  lining your clay flower pot with foil,  put the dull  side
    against the pot and have the shiny side facing outward so that it
    will radiate the heat toward the flask. Use plenty of  foil  so that
    you   totally cover the inside of the pot  as will as bringing it 
    well up over the outside of the clay pot. Use heavy duty foil, or two
    layers of  the thiner foil.   Also be sure to poke a hole in the foil
    so that the bottom of the pot will be open  and the fumes can excape
    from it. 

    One important point is to select a size of flower pot that will
    totally cover  the heating coils of your burner thereby directing
    all the heat to the inner part of the flowerpot. You  don't want the
    pot to rest on the coils,but to extend out over them and rest on the
    burner. 

Good luck.  Alma
