Ever wonder if certain brands of gouache get more moldy than others? Have you ever spent two months of your life observing moldy gouache just for fun? No? Ok. I'll show you what happens when I purposefully let my gouache get moldy in order to compare 12 brands of gouache in airtight travel palettes. Now obviously a normal person wouldn't WANT mold to grow, and usually we take measures to prevent it. But for this experiment I wanted to know if any particular brand was more prone to mold, and in what circumstances.
Just because a brand of gouache might get moldier than others, doesn't mean it's bad! It just means it has certain ingredients that bacteria like to eat. It also means the paint probably doesn't contain biocides. Ultimately that is more natural than others...so is it really a bad thing? It comes down to how you use it.
