    I just used this method originally posted by JD in September. I
    thought I'd post my little testimonial. 

    I cast 3 flasks - silver, 18ky and 14kpd white gold - all of them
    came out beautifully. thanks, Miche 

          It's all in the steam. When I was told about this method, I
          thought it was some sort of fictitious urban legend and refused
          to try it for months. I tried it successfully on a Christmas
          Eve emergency and used the method for every casting after that
          for many years, with both original hard carved waxes and
          injected waxes. The only drawback I ever had was when I was
          casting seven or eight 7" flasks in one burn out and fried a
          coil in my oven with the steam. It especially was nice when
          electricity costs in San Diego, where I was at the time, went
          through the roof. 

          This will sound crazy, but try it once, I guarantee it will
          work. Here it goes...after investing (with no special
          investment) let the flask sit for 20 minutes or so. Take off
          the rubber base and submerse the entire flask completely under
          water, under your bell-jar, vacuum at 30lbs. until the bubbling
          almost stops, (about a minute or two). Place the fully
          saturated flask in a 1350-1400 degree oven and hold for about
          an hour, or until the sprue hole is clean and white, (often
          less then an hour), turn off the oven and open the door, drop
          the temp to the desired casting temp, close the door and hold
          for a five or ten minutes(depending on flask size)and cast.
          Heavy or light, white or yellow, 14 or 18k, you will have a
          perfect cast piece in less then two hours. 

          I know, it goes against all that I have ever learned, but it
          really works. 

          All I can figure is that it's all in the steam. 

          JD
