Custom paint mixes never match on the first try

I've been getting paint from the same place for years, but lately every mix is a bit off. It adds so much time to each job when I have to tweak it myself. Is this just a problem with modern pigments or what?

Honestly, maybe humidity's messing with the base before it even gets mixed.

My glaze went totally grainy last August in that swampy heat, like it absorbed water straight from the air. I keep my dry ingredients sealed with those silica packets now, which helps a lot.

Saw a potter's blog post last year that talked about this exact problem! They said some glaze materials, like gerstley borate, suck up moisture like crazy. Even with silica packets, if the container isn't totally airtight, you can still get grainy glaze. The blogger recommended double-bagging with heavy-duty zip locks and adding extra desiccant. I tried that with my own supplies and it made a huge difference. Humidity is a real beast for potters!
