Hello all,
I'm looking for a glaze that is a honey colored clear.
Does anyone have a good formula for cone 10 or cone 6?
Oxidation or reduction.
Thank you for your help,
Sylvia

Oxidation cone 6
This glaze can run - test to see what works for you. The Gerstley can
cause subtle differences depending on what batch of gerstly you have.
Over Toby's (Randy's Red) it gives a carmel gold color. It does really
lovely things over Floating blue and Raspberry as well as with other
glazes. As I said, it has the fault of running so you have to know what
you are doing.
Honey HM = 35
Spodumene 3000
Flint 2000
Gerstley B 1400
Talc 1300
Dolomite 700
EPK (Kaolin) 500
Bentonite Flocculent (add 1st) 200
Rutile Colorant 600

Sylvia,
This is a honey amber glaze that I used a few years ago. Hmm, several
years ago.
20 dolomite
20 frit 3134
20 spodumene
20 OM4--recipe called for ball clay
20 flint
2 bentonite
3 manganese dioxide
5 RIO
Please note that manganese dioxide is toxic. The glaze has tiny bubbles,
sometimes a sort of tea-dust effect, also tends to have soft brown
speckles, which may not be what you want. But it is a lovely honey
color and does show texture.
You can see a bowl with this at

It's cone 5 or 6 oxidation.

The guild did some 50 - 50 tests at cone 6 a few years ago.=20
Among other things we tried Redart and 3124 frit. Shiney,
transparent, honey-amber colour. Nice and simple.

This glaze has a very low calculated expansion - if anyone wants to try an
adjusted version with a higher expansion let me know - RR

This glaze is a little short of silica - adding more flint would make it
more durable.
Without the iron and manganese the expansion is getting low - RR

One of my favorite cone 6 variants is Ron/John's Spearmint substituting a couple percent of RIO for the copper. Very nice honey.
Test for color and thickness - can crawl if too thick. A normal cooling cycle in an electric kiln will give a nice transparent, glossy surface that will really show off any relief carving and edges. I do work with white clay bodies, it is not as nice on dark bodies. A slow cooling will give a lot of crystal growth and more of a solid color.

Hi Sylvia;
I managed to get a great honey colour out of my own clear base glaze. The colourants are 1.6% Red Iron Oxide and 0.2% copper oxide. You may want to run a line test in your own clear base using that as a starting point. Hope that helps.

I would really like to see it reformulated for educational purposes. The
glaze fits Standard Ceramic clay 112 (same as 225) and everything else
that has come from there as far as I know (the studio has gone through
quite a number of different clays and has not had a problem with it).
Thanks, Donna

The crazing can be eliminated using spodumene if needed.

Hi Lela,
Looks like a durable glazed - and the expansion is low enough to prevent
crazing on most bodies.
Red Art is a variable material so watch for some variation when new Red Art
comes in.

Hi Donna,
Keep in mind - I think of between 450 and 400 as being a good expansion
rate to aim for for most clays. Ive used Aussi spod and the old analysis
for GB.
So the original - I'vereduced to 100 + the bentonite and rutile.
Honey HM = 35
-----------------
AUSI SPOD........... 33.50
SILICA.............. 22.50
Gers Borate 9/97.... 15.50
TALC................ 14.50
DOLOMITE............ 8.00
EPK................. 6.00
BENTONITE........... 2.00
RUTIL............... 6.50

FORMULA & ANALYSIS
------------------
*CaO........ .31 6.85%
MnO2....... .00 .04%
*Li2O....... .22 2.60%
*MgO........ .43 6.84%

*Na2O....... .04 .87%
Fe2O3...... .01 .82%
TIO2....... .19 6.10%
B2O3....... .16 4.38%
AL2O3...... .30 12.16%
SiO2....... 2.48 59.00%
P2O5....... .00 .06%
RATIO 8.25
EXPAN 301.33
WEIGHT 252.42
If I sub in some spar (custer) for the Spod - keep the MgO and the CaO and
the ratio (silica/alumina) the same - chances are the glaze will look the
same.
Keeping the MgO and calcium the same is an easy way to get the same amount
of alkalies ( K2O, Na2O and Li2O.)
I just haved the spod, added that much Custer - saw I had too much CaO and
MgO so added more spar till the CaO and MgO were right - took out some
silica till the ratio was close and bingo - this one was easy cause I did
not have to mess with the EPK or the Talc.
Let me know if you have any questions but seed it all back cause I don't
keep it.
Honey HM = 35 revised by RR for more expansion.
