Hi. What temperature did you use to do the burn out? When we tried it last time, we did not get it hot enough and ended up having nasty black stuff on the outside of the piece.
i burn out at 1100 to 1400F in a vented kiln. you want to have the side down where the ash can accumulate and not be a issue for best surface detail.
I was sand casting, so the only burnout was when the molten aluminum went in. Lots of bubbles, smoke, and fire but it seemed to work well. My intent was to make 2, the 1st one via removing the two halves of the print from the sand, and the 2nd leaving the print in and burning it out with the aluminum. Unfortunately, I didn't pack the molds tight enough on my 1st try and one half fell apart - so I just did part 2...
