I use a round, wide-mouthed container and a spatula for regular water-based glue use. I can pour out the amount I need; if it dries out because I left it too long, no biggie. It was a small amount to begin with. This setup prevents contaminating your glue with dried bits, leather, and color bleeding.
Our container has a wide opening so you can use a spatula, brush, or nearly any applicator. I keep two in rotation, so they’re easier to clean. I pour my project amount into one container and use it until it’s empty. There’s usually a build-up of dried glue on the edge where you scrape excess, on the sides and between the threads for the lid. I leave this nearly empty container open until it dries out overnight. The next day, I can simply peel off the dried glue and have a fresh new container to use. I’ll use the second container when the first one is drying out, so I’m never without a glue pot. Most of my glue is still in the original container, uncontaminated, and seldom exposed to air. This lengthens the shelf life of my glue and reduces waste. I similarly have two spatulas that I maintain in the same cleaning rotation.
