I Finally Bought Mold Release Spray! - Permanent Mold Casting with New Molding Bench!

[@timrobertson299]

We have used that spray on graphite for years in our lead operation at work, it works very well.

Boron Nitride coatings are perfect for this. pretty expensive for a can but it should last a while. you can also coat the ladle with the spray

if you could skim the moulds maybe they would mate up again?

Will graphite work in a muffin tray mold?

[@greensnmachines]

I wouldn't advise eating the muffins cooked with graphite lubricant. Unless you're talking about casting ingots, then probably yes.
