What does vinegar do in glue?
The acid (vinegar) breaks down the protein (casein). This causes the casein to precipitate (or come out of solution) and coagulate (or clump together) into solid lumps called the curd. The leftover liquid is referred to as whey. When filtered, the curds remain in the filter paper and are used to make the glue.
