Grape, 773 along with Dark Plum, 775 were the first purple tones in the borosilicate palette.  Grape, 773 is a dark translucent rod and the rich nature of its color really pops when applied over white.  In sculpture it will reflect black and transmit purple light.

Working Tip: Work in neutral flame to avoid reduction (gray streaks).

Double Passion provides the artist with an easy to control amber to purple striking color.  Since Double Passion is less saturated than its older sibling Triple Passion, it does not strike as dark as fast, providing you with the opportunity to develop intense pink and magenta colors.

Triple Passion, 786 was introduced as an easy striking amber to purple color.  Due to its formulation this color quickly, easily and consistently strikes through a wide range of bright and delightful purples.  The use of color-changing borosilicate exploded soon after Glass Alchemy introduced this color to the market.  This is a must have in every glass studio!

Working Tip:  Get this color white hot to erase the striking history.  A variety of effects are achievable depending on how long you flame/kiln strike.
