TURQUOISE LUSTRE (Beautiful copper in heavy reduction) lovely turquoise with copper in light reduction.

Frit 4110= 100

Copper carb =3

Bentonite = 2

Tin Ox = 3



Neph Syenite = 5

Neph Syenite = 20

Bone Ash = 20

Cobalt Carb = 3

Copper carb = 7

Gerstley Borate 80


COPPER LUSTRE (Nice copper semi matt)
- needs heavy reduction in dark sawdust

Frit 4110= 74

Neph seyenite = 11

Ball Clay = 5

Kaolin= 3

Tin Oxide = 2

Ferguson’s White Crackle

Nepheline Syenite = 20

For excellent crackle results, fire your pot, take out of the kiln and allow to rest for about one minute.  When glaze 'pings' put the pot into the reduction container, cover with paper, allow to flame, then close the cover.  Leave for about two minutes, lift the lid and allow the paper to re-ignite.  Close the cover again and leave to reduce and cool normally.
