It's one of the most common questions we get at Artmount & Framing Matters: "Does the glass actually matter?" Short answer: yes, it really does. And not just for aesthetics. The glass you choose plays a significant role in how long your artwork stays looking the way it does today. Get it right, and your piece will look great for decades. Get it wrong, and you might be looking at fading, yellowing, or worse — and wondering why.
