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.
