The following recipes have kindly been put together by Barbara Hanselman, Cherry Hill, NJ, USA.

You can vary the Copper Carbonate from 3-5% with great results and still be food safe.

SAPPHIRE BLUE - a Ron Roy reformulated recipe which breaks nicely on edges.Breaks green on light clay bodies, black on dark clay bodies.Apply medium to heavy.Good for functional and decorative ware.

CURRIE BLUE - A butter finish matte which has a lot of interest, breaks nicely and holds it’s own on all clay bodies.Very opaque but with interest.

CURRIE BLUE

BACH’S BLUE GREEN- A glossy semi-transparent glaze which holds on even the darkest clay bodies.Overlays well with Randy’s Red; great over blue, green & red oxide stains.

BACH’S BLUE GREEN

LYNN’S GLOSSY GREY & LIGHT BLUE GREEN - A glossy glaze with a lot of movement.Looks best on textured surfaces or over engobes with red iron and red iron oxide stains.

STRONTIUM WEATHERED BRONZE AND WASHED DENIM BLUE - a great weathered-looking glaze.The bronze goes from a clear, bright green to a brownish bruised green and is suited to all clay body colors, although it is best on tans.The denim blue is not tested.

TRONTIUM WEATHERED BRONZE

STRONTIUM TURQUOISE MATTE Cone 5 - The ingredients in this glaze are the same as the ones in Strontium Weathered Bronze; only the amounts vary slightly.A beautiful matte turquoise glaze!

TECO GREEN - A Tom Zwierlein matte glaze based on a Val Cushing recipe.Reminiscent of the green to grey glaze found on American Art Pottery known as Tecoesque.Really greys out to an ugly color on white stoneware if applied too thick but holds it’s own on other clay bodies [from tans to reds to browns] producing different, interesting effects.

TECO GREEN

METALLIC GREEN METALLIC GREEN - This metallic luster glaze looks awesome on clays with iron - Laguna’s Electric Brown, Hawaiian and Standard’s 266 Brown or over engobes or stains made from red iron oxide.Both the Sky Blue and Ocean variations also produce metallic lusters and look best on iron rich clays, stains and engobes. Three brushed-on coats really cover well; if more translucency is desired, one heavy or two lighter coats do the trick.

ADD Colorants:

RANDY’S RED & BLUE - a glossy, translucent glaze which works better as a liner or “inside” glaze.The red goes very orange if re-introduced to a bisque firing after a cone 5-6 firing.The blue is very lavender with specs from the cobalt oxide.Apply medium to heavy, especially outside.Can be runny.

BLACK GOLD MATTE - A great bronze black metallic for all clay bodies at cone 5-6; apply medium.

BLACK GOLD MATTE

This is my favorite of the golden bronze looking glazes!

BRONZE - Bill Shillalie’s version for cone 02-6.This recipe is so similar to my favorite above that I decided to hold on to it and test it one of these days.The other two are more options.

BRONZE 3

PERKIN’S MATTE BLACK - A matte gunmetal black which stays put - great for wax resist design work.This glaze works on all clay bodies but tends to pinhole if too thick.
