Here are a slew of recipes I have gathered from those on Clayart:

NAKED RAKU Resist Slips and Glazes To Go With Them

David Roberts resist slip (EPK)Kaolin 3 parts by volume Flint 2 parts by volume Copper Oxide 10% (or none)

use with the following glaze Raku Crackle Glaze (by David Roberts in Sawdust Firing) High Alkali Frit 45% Soft Borax Frit 45% China Clay 10%

Fire to 1562-1652F.

Glaze Marie-Claire in the Netherlands 90% Borax frit 10% kaolin ____________________________________________________ Resist Slip Marie-Claire 2 parts kaolin 3 parts flint or silica

works with

Glaze Frit 3110 65% Gerstley Borate 35%

don't use this glaze with the Roberts slip __________________________________________________ Jacobsons' Slip and Glaze Slip 40% Lincoln 60 fireclay 30% 6-Tile clay 20% Ione 412 Grog 10% Custer feldspar

or this variation used without glaze

Chip n Slip 40% Hawthrone Bone or A-P Fireclay 30% Kaolin 20% Pyrotol (or grog) 10% Custer Feldspar

Glaze 60% Ferro Frit 3110 40% Gerstley Borate

Bisque to Cone 012-010 Fire to cone 014 (1540F.), smoke, water-quench, peel ___________________________________________________________ Gordon Hutchens Slip used without glaze

Fire Clay 50 EPK 30 Alumina Hydrate 20 (or 10% for easier removal)

Marci Masterson (From Sharon in Fort Worth) #1 Fire Clay 40 grams #6 Tile 30 grams Custer 10 grams Grog (28 mesh) 20 grams

#3 Fire Clay 50 grams EPK 40 grams Soda Spar 10 grams (Add 5 - 15% grog)

#4 Fire Clay 50 grams EPK 35 grams Nepheline Syenite 15 grams (add 5% grog - no more)

#5 Fire Clay 45 grams EPK 35 grams Flint 10 grams Nepheline Syenite 10 grams (add 5% Grog - no more)

Notes: (can't find #2) #1. If fire clay is gritty, don't need grog (or need less grog). Interesting small design w/o grog. Marcie uses 10% grog. Apply one thinned coat crubbed. Removes very easily.

#3. Similar to #1. Marcie uses 10% grog.

#4. Semi straight edge design. Applies 4 even coats. Thinner and smaller design. Removed easily.

#5. Fairly straight edge design (almost geometric). Hard to remove. Apply like #4. Used w/o grog is good but small.

Additional notes: Every thing with talc "fused". Try other fluxes; try other clays. Almost all recipes will work with 25-50% raku claybody w/grog or sand. Mix slip to a consistency where it will just "pour" not "plop" off a spoon.

The following is the glaze recipe which is applied over the slip:

70% Ferro Frit 3110 30% Gerstly Borate

Mix "milk" thin and apply thinly.
