Buying Guide: Key Purchase Considerations
- What technique will I use most—glazing, varnishing, pouring, or mixing with colors? Pick a medium that emphasizes that use (gloss glaze vs. pouring).
- What level of gloss and transparency do I need? Some mediums enhance depth and translucency; others emphasize surface shine.
- How does the medium affect drying time and flexibility? Consider resin content and compatibility with other acrylics in your kit.
- Is safety important for education or family use? Look for ACMI certification and non-toxic formulations when applicable.
- How will the medium interact with textured surfaces or impasto? Some gels and pastes maintain brush marks or add dimension, while others level for smooth sheets.
