PrimaTone Burnt Sienna – Transparent Oil-Alkyd Paint with Genuine Earth Pigment (PR102)

PrimaTone Burnt Sienna

Fast-Drying Oil-Alkyd Paint for Professional Results

PrimaTone Burnt Sienna is a rich, transparent reddish-brown earth color made from natural calcined iron oxide (PR102), sourced from high-grade deposits in the United States. Valued for its warmth, depth, and flexibility in tonal work, Burnt Sienna is a studio essential for classical and contemporary artists alike. Ground in a durable oil-modified alkyd binder, it dries evenly to a matte or semi-gloss finish within 18 to 24 hours—perfect for artists requiring reliable drying times without sacrificing the expressive potential of a traditional pigment.

With its moderate tinting strength and excellent transparency, PrimaTone Burnt Sienna is ideal for glazing, warm shadow development, and underpainting. Its chromatic subtlety and responsiveness make it a versatile color for portraiture, landscape, and figure work—enhancing compositions with glowing undertones and smooth transitions.

PrimaTone—Fast-Drying Oil-Alkyd Paints

PrimaTone paints deliver the trusted characteristics of traditional oils with the added benefit of accelerated drying. Colors are touch-dry in 18–24 hours and ready for varnishing in approximately 30 days. With a working time of 4 to 8 hours, artists can refine and blend with ease before the paint sets.

All PrimaTone colors dry uniformly to a matte to semi-gloss surface, making them ideal for both foundational layers and final applications. The combination of lightfast pigments and a resilient alkyd binder ensures a long-lasting paint film. Compatible with traditional oil mediums and easily cleaned with mineral spirits, PrimaTone offers a practical solution for artists seeking speed without compromise.

Safety and Toxicology

PrimaTone Burnt Sienna contains Pigment Red 102, a natural calcined iron oxide recognized for its excellent stability and low toxicity. It presents no known chronic health risks under standard studio conditions and does not require special hazard labeling in compliance with ASTM D4236.

The oil-modified alkyd binder includes a small amount of hydrotreated petroleum distillate, a high-flash, low-odor aliphatic hydrocarbon used to improve handling. At the concentration used, it does not trigger chronic hazard labeling for art materials intended for adult use.

As with all oil-based paints, observe standard precautions: avoid ingestion, do not sand dry paint films, ventilate your workspace, and wear gloves if skin sensitivity is a concern.

All components—pigment, binder, and additives—are clearly listed on the product label, in keeping with Natural Pigments’ commitment to ingredient transparency. Store in a cool, dry place and keep out of reach of children.
