The epoxy resin used is derived from museum conservation-grade materials to ensure its clarity is preserved for decades. Many resins contain a UV stabilizer to help delay the epoxy's natural yellowing process, however this alone is not enough to prevent yellowing from happening. This epoxy resin contains both a UV stabilizer as well as an advanced additive called HALS (hindered amine light stabilizer) that interrupts the yellowing process before it can begin. The result is that it stays clear both in the bottle and once cured.
The frame is made of solid Poplar, biscuit joined, with at least 2 coats of polyurethane.
