This artist-quality additive from Pebeo makes it easy to produce beautiful cells, fractal effects & more during your pouring projects! Only requiring a small amount to produce these effects, you can incrementally add this drop by drop using the convenient in-built pipette for accurate measurements & applications. For instance, dependent on the desired effect, in a medium colour mixture a maximum of 3-8 drops will be sufficient. Please be aware that applying too much Silicone Oil can potentially cause "holes" to appear in your work.
