today's casting

[dallen]

yep, the two halves together make a flask, the one with the pins is called the drag it goes normally on the bottom, the one without pins is called the cope and normally is positioned on top. If the alignment pins are long enough you can put the heel of you hand on top and grasp the lip of the handle and raise the top half straight up to clear the pattern without tearing the same which causes some of the jagged edges you see on a lot of my castings.
