Gamblin refines petroleum to medical-grade standards, removing the aromatic hydrocarbons that cause odor and health concerns in standard mineral spirits. What remains is pure aliphatic solvent, effective for thinning oils and mediums without the headaches, literally. The slow evaporation rate gives you working time; paint stays open longer on the palette, and you're not constantly breathing vapors as solvents flash off.

Gamsol maintains the cleaning power oil painters need. Brushes rinse clean, palettes wipe down, and mediums thin to proper consistency without leaving residue. The high flash point of 145°F provides safety margin during studio work and storage. Combined with Galkyd mediums, you can paint in spaces without dedicated ventilation systems, apartments, shared studios, home workspaces, where traditional solvents would be problematic.

The permissible exposure level exceeds standard mineral spirits significantly, meaning extended painting sessions don't require respiratory protection under normal use. Pour it into brush washers, use it for paint-out rags, thin your medium mixtures. Studio cleanup becomes straightforward rather than an ordeal involving fumes and forced air circulation.
