Synthetic Sizing

I’m a vegan. I’ve heard that some companies use animal products as part of their sizing process. What is paper "sizing?" 

Sizing is applied to paper in the papermaking process to make sheets less porous. Without sizing, paper would react to moisture like a blotter. The type and amount of sizing applied to paper varies with each type based on the desired working properties.

Drawing paper is sized for surface strength, helping protect the surface for erasing. Watercolor paper is sized to help produce a consistent wash as well as help the scrubbing and layering of colors. The majority of our products use plant-based and synthetic sizing.
