Back around 2004 I was given a small (2.0 oz) bottle of colloidal graphite in isopropanol. Have enjoyed success coating my molds with it before casting. I de-grease my molds with carb cleaner, clean cotton rags and Q-tips. I then coat the mold with the graphite. It dries on fast and I usually give the mold a second coat. The boolits drop out of the mold easily and lead sticking to the mold is not a problem. Does anyone know where I can buy some more of this? The label on my bottel can not be read.
Also I believe that the graphite maybe working as a lube on the sprue plate pivot. I have been reluctant to try bees wax on it as I fear it will flow into the mold cavity and screw up the quality of the casting.
Would like to hear from those of you in the know.
Thanks, Sendaro
