Look. If you paint with acrylics and you have not tried GOLDEN Heavy Body yet, this is your sign and we are not sorry for the intervention. Red Oxide (S1) is part of the range that put GOLDEN on the map in 1980, and it genuinely keeps getting better. A 59ml tube of thick, richly pigmented acrylic with a buttery, knife-holds-its-peak consistency. The kind of paint that makes your mark-making feel like it actually counts for something.

What Makes This Colour Special

Red Oxide is a single-pigment colour (PR101). That matters more than most people realise. Single-pigment paints mix cleaner, stay truer, and give you far more predictable results on the palette. No hidden extras, no surprises.

Red Oxide is fully opaque. What you put down, stays down. Strong, decisive, not messing about. Perfect for solid coverage and for painting over your earlier experiments.

Lightfastness is rated ASTM I — the highest possible. Not a marketing claim, a tested, verified fact. Your work will hold its colour for well over 100 years under normal indoor display conditions. The kind of promise you can make to buyers.

Why GOLDEN Heavy Body is in Serious Studios

• No fillers. No extenders. No dyes. Pure pigment in 100% acrylic emulsion. That is it.
• Buttery consistency that holds its peak. Brushstrokes stay. Palette knife marks peak and stay peaked. No overnight slumping.
• Batch-to-batch colour consistency. Every production run is matched. Your palette does not change on you between orders.
• Permanent and waterproof once dry. A flexible, archival film that will not crack, yellow, or reactivate with water.
• Fully intermixable with all GOLDEN mediums, gels, and pastes. No weird reactions, no surprises. Also plays beautifully with other professional acrylic brands.
• Series 1 pricing — based on pigment cost and rarity, not quality. Every series is made to the same uncompromising standard.

About Series Pricing

GOLDEN uses a Series 1 through 9 pricing system based purely on pigment cost and rarity. Series 1 uses the most accessible pigments. Series 9 uses the expensive, rare ones. What it does not mean is that Series 1 is lesser quality than Series 9. Every single series is made to exactly the same uncompromising standard. Red Oxide is a Series 1 colour, priced at $21.95 per 59ml tube.

Getting the Most Out of This Tube

Straight from the tube is where Heavy Body shines. Impasto, texture, bold mark-making, palette knife work. This is exactly what it was designed for.

Thin with water up to around 25% for smoother applications. Beyond that, reach for GOLDEN Fluid Medium or Glazing Liquid — heavy dilution with water alone can compromise the binder over time.

Need more working time? GOLDEN OPEN Medium or a touch of Retarder slows drying significantly. Wet blending, soft edges, all the things oil painters get to brag about — all possible.
