how to remove glass chip?
I have this 30-day old starter, raised from five-roses unbleached all-purpose. First 20 days I fed with 1:1:1, it capped at 20% rise and I switched to 1:2:2. Now notice the acetone smell is gone, and it reaches 50% rise occasionally.
This morning, I noticed a red dot on the glass, I thought it was the pink disease. But after investigating, it was a broken round glass chip inside the lid. There might be some minerals in the glass voids reacting to the sourdough and causing a red mark (I didn't take a picture).
I then took 20g of sourdough to a new jar and continued feeding. I cleaned the old jar and noticed the big chip torn off. Now I am afraid of glass chips in my sourdough. I threw away all discards I had been collecting, but the active sourdough might still be contaminated by the shards.
Perhaps if I keep feeding with new jars, there will be enough dilution to remove the shards?
Edit: To give more context, I think the jar I used was very low-quality with small air bubble pockets in the glass. The sourdough got into the air pockets and broke the thin glass off. The image shows how much glass was chipped off after I scrape off the sourdough and clean the jar.
