DiVolo Petroleum essence is a mineral solvent

Description

Artistic Context

• Petroleum essence is preferred by artists when they want a solvent that evaporates cleanly and doesn’t interfere with paint layers.
• White spirit is more common in general painting and household use, but it can sometimes slow drying or leave traces.

Key Properties

• Physical state: Clear, colorless liquid
• Odor: Strong
• Volatility: High — evaporates quickly without leaving residue
• Flash point: Above 21 °C (so it’s flammable, but less so than lighter solvents like acetone)
• Density: About 0.888 kg/L, slightly lighter than water

Uses in Art & Painting

• Oil painting: Added in small amounts to thin oil paints, making them more fluid without altering drying time too much.
• Varnishes & mediums: Useful for diluting natural resin or acrylic resin-based varnishes.
• Printmaking: A few drops can make chalcographic (engraving) ink more workable.
• Cleaning: Because of its solvent power, it can help clean brushes or dissolve certain resins.

⚠️ Safety Considerations

• Highly volatile → always use in well-ventilated areas.
• Flammable → keep away from open flames or sparks.
• Strong odor → prolonged inhalation can be harmful, so protective measures (like masks or good airflow) are recommended.

What’s interesting is that petroleum essence sits somewhere between turpentine and white spirit: it’s purer and evaporates more cleanly than white spirit, but less “natural” than turpentine. Artists often choose it when they want a solvent that won’t leave oily residues or slow down drying.
