Notes

After the cool-down:

 

filled_form_top_sm

Form filled to the brim with black glass.

 

pot_drop_sm

Glass drip frozen in mid-air…

 

crucible_sm

The glass billets left a nice “imprint” in the crucible/funnel…

 

after_cast_sm

So you open the kiln and behold: none of the molds broke and the glass seems to have melted nicely into the forms.
