More White titanite Chunks than I know what to do with

I have like 30 white titanite chunks on my main melee build (SL 152). My faith on this build is low (14). What's the best thing for me to do with these chunks? I can upgrade some occult weapons I have but with my low faith, it doesn't seem like I would get any useful weapons out of it. I only get 50 souls a piece if I trade them with Frampt so that doesn't seem like it's worth it either. Am I stuck with a bunch of useless white titanite chunks?

You can actually break them down into other titanite pieces by having them in your inventory when you speak to him. I don't know what path they go down, but I imagine they break into green then shards. Who knows they may even break into larges I sure as heck know they are a pain in the butt to get when you need them.

they break down to the green ones.

Sorry if this is a dumb question but how do I "have them in my inventory" get Frampt to break them down to green ones. I don't see an option to "Feed White titanite Chunks" in the main dialog menu with Frampt?

that's trange....they should show up just as the normal titanite chunks..
