Looking back at old replies to similar questions and I tried a grinder pit-- only to find out it won't touch ingots, ore, or components (then I read the wiki which says this). Specifically, it's (2Mkg) silicon I'm trying to get rid of as there's little use for it compared to the iron and nickle I get from stone processing. While an incinerator block would have been awesome if Keen ever made one I'm wondering if my only recourse is a pit and dumping the silicon ingots into it like a landfill, hoping the trash collection function will delete some of it before I'm lagged to heck.
