Somewhat Different Lost PLA Process

 

Xalthran — Today at 9:49 PM

I have actually never used PoP for lost PLA, but I -did- do a thin coating of investment and surrounded it with homemade sodium silicate bound sand. Poped it in a small toaster over for a couple hours then threw it in my small kiln along with the silver I was melting and simultaneously pulled the mold out and poured the silver.
