Garzoni Giovanna is also known as Botero.  Work this glass in a neutral to oxidizing flame when you melt this glass.  When your bead is formed and you are ready to bring the colour out of this glass, reduce repeatedly to encourage the colour.  This should be done at the back of the flame. The more you do this, the better the colour result will be. You can bring the silver to the surface by using a heavier reduction flame. 

Striking Guide for Precision 104 Colours:

Use adequate ventilation when using silver rich colours.

Use a neutral flame (shortest yellow candle) while constructing your bead.

Remove your piece from the flame until the glass loses it glow.

Adjust your flame to slightly reducing (longer yellow candles) by turning propane up or oxygen down.

Reheat your bead until the glass is glowing again.

Remove the bead from the flame and watch the colours develop. To further develop the colours repeat.

To clean off any effects reheat at the tip of an oxygen rich flame.
