Well, so far I've done roughly 600lbs. Molds work great. The first ingots to drop are a little wrinkled as expected due to cold mold but after that, beautiful.
Having no trouble getting them to drop, let them cool a few minutes, grab with vice grip, a rap or two on the table and done. Refill and repeat.
I prefer not to link mine because i'm storing them in the small flat rate boxes from the post office and they wouldn't fit if linked. With my ladle the ignots consistently drop just over 2lb 1oz giving me 25lbs per box, makes it easy to inventory with every 4 boxes being a 100lb.
Now only 1500lbs to go..........
These are perfect for my needs. Thanks again Lakehouse!
