Vent: My ink mix ate through a pen feed in under a week

I was in my garage workshop last Friday, testing a new purple I made with 3 parts standard blue and 1 part red sheener. I filled a cheap demonstrator pen to see the color. By Wednesday, the feed had turned cloudy and brittle, and ink flow was a mess. I think the red sheener was way more acidic than I realized, and it reacted badly with the plastic. I had to toss the whole pen. Has anyone else had a specific ink component damage a pen body or feed? I need safer recipes.

Honestly, that sounds more like a bad pen than a bad ink mix. I've seen cheap demonstrator feeds get cloudy just from regular ink sitting in them too long. Tbh, the red sheener is probably fine, those plastic feeds can't handle much of anything. I mixed a super saturated dark green once that everyone said would melt pens, and it's been in a Preppy for months with no issues. Might just be that particular pen body was already weak.

I always blamed the ink, but your Preppy story makes me reconsider.
