transparent golden yellow flame: OxidizingYellowAmber

Work in an oxidizing flame to achieve a clear, transparent golden yellow.
darkened, increasingly opaque yellow flame: Reducingstrike: Flame Or KilnYellowAmber

In a neutral to slightly reducing flame the glass begins to darken and turn more opaque; flame or kiln striking can develop this further.

Neutral or reducing flame will darken and opacify the color — adjust flame chemistry to control transparency.
