REDUCTION GUIDE for Aion, Elektra, Gaia, Kronos, Nyx, Psyche

1. Use adequate ventilation for silver rich colours.
2. Shape you piece in a neutral flame. (shortest yellow candle)
3. To begin the reduction process; remove your piece from the flame and allow to cool until no longer glowing hot.
4. Set a slightly reducing flame by turning your gas up.
(longer yellow candles)
5. Pass your piece through the reduction flame for a few seconds. (time to reduce varies by colour)
6. Remove your piece from the flame and check the reduction progress.
7. To further reduce the piece, repeat steps 5-6.

*Clean off undesired results in an oxygen rich flame.

*Hot head users can produce a reduction flame by temporarily covering the air inlet holes with a hot pad or a fusing glove.

STRIKING GUIDE for Khaos, Luna, Triton and TerraNova2

1. Use adequate ventilation for silver rich colors.
2. Work in a hot neutral flame. (shortest yellow candles and no streaks)
3. To begin striking; allow the piece to cool until no longer glowing hot.
4. Gently reheat.
5. Anneal at 940F.

*Working too cool can result in milky colours.

**Multiple heating/cooking cycles can further develop the colour, though a single cycle of the right durations yields the brightest colours.

TIPS for specific colours:

Aion- Works best over dark colours.

Gaia- Compared to Aion and Kronos, Gaia has a much shorter striking time. In just a few passes in the reduction flame it will strike fully.

Elektra- It's nearly impossible to overstrike. Almost the opposite from Gaia, you can have it in a reduction flame for longer periods of time and it will just get redder.

Nyx- Can also be struck in the kiln. Depending on placement, time and temperature, Nyx will fade through a series of blues.

Luna- Work very hot. The hotter it's worked, the brighter the results.

Triton - Work in a neutral flame, allow to cool for a few seconds, reheat far out in a large reducing flame.

  • AION 2

    AION 2

    Priced per pound as shown and sold in 1/4lb increments. Reduction colour. This well balanced formula is easy to strike and hard to mess up.
    • CA$94
  • ARKE

    ARKE

    Arke can develop exterior metallic finishes of silver, gold, green, red and blue. Variations in flame chemistry, exposure time and temperature alter which metals are deposited on the surface of the glass. The green metallic finish in the photo was achieved using a "hot" reduction flame. The silver tone resulted from brief exposure to a "cool" reduction flame, while the red tones were developed by repeated reduction. Contrast between these metallic finishes can be highlighted by using a small oxidizing flame to remove the metallic ouster from selected portions of the bead, the re-exposing the bead to a reduction flame, building the metallic layers of alternating composition. Priced per LB as shown and sold in 1/4 LB increments

  • ATLAS

    ATLAS

    Priced per pound as shown and sold in 1/4lb increments.

    Atlas is a highly saturated striking color, four times as strong as Skiron. Pure silver is the only colorant. Atlas can produce a range of colors both transparent and opaque, including ambers, purples, blues, and greens.  It works well in both surface and encased applications.  Super-heating can cause phase separation, creating patterns in the final outcome.
    Formulated with the same nucleation system as Skylla, Skiron, Terra3, and Ekho2.  Atlas is easy to strike using the reset/cool/warm sequence. It is very responsive to varied thermal history, allowing the development of many different colors on the same piece.
    Our benchmark times for surface application are Reset/30 seconds cool/30 seconds strike. A clear encasement layer adds about 15 seconds to the cooling and striking times. Specific times and color outcomes will vary depending on several factors.

  • AURAE

    AURAE

    Priced per pound as shown and sold in 1/4lb increments. Also known as "pinky-purple luster." If you love Triton, you'll love his pink baby sister!
    • CA$94
  • CHLOE

    CHLOE

    Chloe is a green, speckled, luster glass. The speckling comes from thousands of refractive inclusions dispersed throughout the glass. When reduced and encased it creates a textured mother-of-pearl effect. Priced per pound as shown and sold in 1/4LB increments
    • CA$94
  • CLIO

    CLIO

    Priced per pound as shown and sold in 1/4lb increments.

    Clio is the first colour-shifting, reducing and striking glass. The colours will shift in different light sources. Once struck or reduced that colour shift is altered. Thus, many colour outcomes are possible with this unique colour chemistry.

    • CA$117
  • EKHO2

    EKHO2

    Ekho2 is a dual color, capable of both reducing and striking. It works best if you choose one technique or the other. Ekho2 is a reformulated version of Ekho. The nucleation system used in Skylla and Skiron has been added, resulting in a glass that is easier to strike.

    Ekho2 can be used as a surface luster, an encased pearlescent luster, struck on the surface, or struck under a thin encasement layer.

    • CA$94
  • ELEKTRA 2

    ELEKTRA 2

    Priced per pound as shown and sold in 1/4lb increments. Reduction colour. New formula resists boiling and kiln burn off.
    • CA$72
  • ELPIS

    ELPIS

    Priced per pound and sold in 1/4 lb increments

    Elpis is a chrome-free green reducing glass that is resistant to over reducing. She transmits a spring green colour. She's the same as sold out test batch PX-772 from this years online ISGB Gathering.

    • CA$117
  • EUROS

    EUROS

    Euros is an opaque white glass that with different heat treatments can produce lavender veining, a blushed ivory or when reduced can fume to a creamy ivory luster with tiny, gold colored spots. Priced per pound as shown and sold in 1/4 LB increments
    • CA$60
  • HELIOS

    HELIOS

    Priced per pound and sold in 1/4 lb increments

    Helios is a super luster in a golden-yellow citrine jewel tone. The texture shown was made with a Jim
    Moore hand stamp.
    • CA$117
  • HYPERION

    HYPERION

    A relative of Clio and the CX test series. It's a strong reduction color that is designed to strike automatically during the bead making process to medium amber. To maintain the cleanest color, reset Hyperion until the glass appears clear, and reduce very lightly. Encasing the light reduction in clear results in a purple pearlescent luster with a warm, honey coloured undertone. Priced per pound as shown and sold in 1/4LB increments
    • CA$117
  • HYPERBOREA

    HYPERBOREA

    Hyperborea has a rich violet and red colour transmission and easily develops a strong silver luster when reduced.  It works well both in surface applications and under encasement.  
    The colour is saturated and may present best over a core of clear glass, as pictured.  A replacement to Boreas, Hyperborea is made in our updated colour base resulting in cleaner colours, smoother working characteristics and improved viscosity curves.

    • CA$112
  • IASO

    IASO

    Iaso (eye-ay-sow) From test batch AX-598, the bronze version of Iris. Iaso has a high copper content and is capable of yielding bronze metallic exterior lusters. Like Iris, brief but repeated exposure to a small, cool reduction flame produces the best results. The temperature of the beads surface, as well as the intensity, duration, and frequency of reduction determines the final outcome. Variations in the luster can be accentuated by using a very small oxidizing flame to selectively erase portions of the luster, then repeating the reduction process. In our experience, a brush reduction flame produces the best results. Priced per pound as shown and sold in 1/4 lb. increments
    • CA$117
  • IRIS

    IRIS

    Iris is the production version of the most popular test batch from this summer, AX-605. The A was for Arke and the X was for 10 times the strength! This reduction color can yield a multicolored metallic iridescent luster. In our experience, a brush reduction flame produces the best results. Though designed specifically for exterior applications, the silver portion of the luster will hold up under encasement. Priced per pound as shown and sold in 1/4 LB increments

    • CA$112
  • KETO

    KETO

    Keto is a blue-speckled luster based on test batches TC663 and TC665. A relative of both Chloe and Ossa

    Priced per pound as shown and sold in 1/4 LB increments

    • CA$80
  • LOTIS

    LOTIS

    A pink version of Rhea. A lead-free gold pink that plays well with silver colours and survives a reduction flame without discolourations.

    • CA$144
  • MELIA 2

    MELIA 2

    Melia 2 is a chrome-free reformulation of Melia, a teal version of the Arke, Iris, and Iaso family. Different metallic effects are possible depending on the reduction techniques you use. Melia 2 retains its luster under clear encasement. An opaque celadon blue can develop with extended annealing, about one hour at 950F. Lower annealing temperatures and/or shorter times maintain the transparent teal.

    • CA$117
  • NOTOS

    NOTOS

    A silver saturated super luster with a subtle blue-grey-green tone. Repeated gentle reduction can yield pink iridescent lusters. Priced per pound as shown and sold in 1/4 LB increments
    • CA$117
  • OKEANOS 2

    OKEANOS 2

    Priced per pound as shown and sold in 1/4 LB increments

    Okeanos 2 is a blue striking and reducing color. Reformulated with the same nucleation system as Terra 3 and Ekho 2, it strikes to a range of blues, greens, purples and amber. It works well on the surface or encased. Super-heating can cause phase separation, resulting in webbing. Okeanos 2 is capable of developing a subtle luster and retaining that luster under clear encasement.

  • ORACLE BLACK

    ORACLE BLACK

    Oracle-Black has smooth working characteristics, reads "darker" than some existing black glasses, does not spread excessively, and can be worked very hot without boiling. It is made in USA without Antimony, Arsenic, Cadmium, Chromium, Lead, Nickel, or Selenium.  Rods are blue but strike to black during the annealing cycle.  Stays neutral with striking colors but reacts to luster colors.  

    For maximum opacity, particularly in thin applications, briefly cool the bead then lightly flame strike (30 seconds) before annealing for 2 hours or more at 950F.

    • CA$54
  • ORACLE WHITE

    ORACLE WHITE

    The house white that's used for murrini.  This white has a nice viscosity curve, it allows for some light transmission which creates a brighter appearance. It’s good as a base white, in thick stringer and in latticino. It's especially nice under Rhea and the Oracle-Ruby.

    • CA$47
  • ORACLE OPAL

    ORACLE OPAL

    Oracle-Opal, a striking glass that produces a range of misty opal tones. It easily resets to crystal clear, initiating the striking process. After resetting, Oracle-Opal will cool to a faint translucent opalescence. Further exposure to flame temperatures around 1000°F will cause more extensive opacification 

    For Best Results: If you’d like to retain the color effect as-is when you’re done, anneal cool at about 920°F for up to two hours. Higher temperatures and longer annealing times will initiate further striking of the opal. Encasing the Opal will also add heat and time so adjust your annealing accordingly or plan on having more opacity.

    • CA$50
  • ORACLE VIOLET

    ORACLE VIOLET

    Oracle-Violet Opal, a purple slow opal.  This opal is a striking glass that produces a range of misty opal pink tones.  It easily resets to transparent pale purple.  After resetting, it will cool to a faint translucent opalescence.  This opal is “slow” compared to our regular oracle opal, and it may require very gentle flame striking or longer annealing times or higher annealing temperatures to develop substantial opacity.
    For Best Results: Reset the Opal before annealing at 920°F for two hours or more. A translucent, opalescent strike can occur at annealing temperatures above 920F.  Higher temperatures and longer annealing times will initiate further striking of the opal. The opal strike may also be initiated by resetting, cooling, and striking in a very cool flame before annealing.
