Low Fire Friday - Glaze layering (Guest Artist Martina Lantin)

Meagan Chaney Gumpert - Friday, October 05, 2012
What a treat to have Martina Lantin as this month's Low Fire Friday Guest Artist. And Martina is sharing not 1, but 2 recipes with us!  Whoohoo!


I had the pleasure of meeting Martina while we were teaching at Arrowmont School of Arts and Crafts this past August. Though I've know her work for awhile, it's always great to meet the maker behind the handmade. Instantly, I was won over by her easy going, but professional nature and enjoyed conversations we had in and out of the studio all week.

Born in Montreal, Canada, Martina Lantin received her Bachelor of Art from Earlham College (1996) and her Master of Fine Art from NSCAD University (2009).  She has been an artist in residence at Baltimore Clayworks in Baltimore, MD and Arrowmont School of Art and Craft in Gatlinburg,TN.  Currently, Martina is a professor at Marlboro College in Marlboro, VT.

Selected as an Emerging Artist by Ceramics Monthly (2002), her work has been recognized in numerous juried and invitational exhibitions. In 2010 Martina was award an Individual Artist Grant by the Tennessee Arts Commission.  She has also published articles in both Studio Potter and Pottery Making Illustrated.

Committed to the joys of working in earthenware, which she describes as chocolate porcelain, Martina creates functional ceramics through thrown and altered forms.  The thin layer of white slip serves to accentuate the construction methods and to invite an exploration of the making process.


Here are the low fire glazes and application technique Martina is sharing with us today:

WOODY HUGHES BASE GLAZE – CONE 04 – good with colorants
Gerstley Borate 26
Lithium Carbonate 4
Frit 3124 30
NephalineSyenite 20
EPK 10
Flint 10


Colorants can be metallic oxides or carbonates or mason stains, singly or in combination.

Colors in the image:

Blue green:   2% copper carbonate and 3% deep orchid stain
Violet:            5% orchid stain and 1.5% rutile



OPAQUE GLOSS: (rated for cone 015 – as an over-glaze enamel)
Frit 3134 36.4
Pemco ‘P-25’ (frit 3269) 55.6
EPK 8
Add tin 10


Colorants – stains or oxides.  Do your own tests to develop your palette – start with 2 – 10 %



First, the Opaque Gloss is slip trailed onto the piece (in the example photo - the colors you see are from the slip decoration applied prior to bisquing).  Spaces in the design motif can be filled in with colored versions of the Woody Hughes base (brush application works best for filling in areas with color).  Woody Hughes base glaze is applied to cone 05 bisqueware, ideally poured or dipped.

You can also play with waxing over the colored Woody's glazes or not before you cover with the clear glaze – depending on the fluidity desired.  The clear Woody's Base glaze can be very thin for dipping, however when the stains or oxides are added for the colored glazes, thicker is better for brushing purposes.

Martina then fires to cone 03 using a kiln sitter or cone 04 when using a computer program with cone 04 on the program and 25 minute hold at the end.

So, there you have it! Martina let us in on some of the secrets of how she gets such beautiful, fluid results in her work!

Hope you're having a wonderful Friday!
