Dear Ababi,
When you wrote about the miraculous engobe that allowed one to reglaze a
pot on top of a less than successful glaze,I immediately bought Lana's
book.
I used her dry engobe with disastrous results. I covered the original
glazed surface,on the inside of a bowl, bisqued the bowl, then applied a
cone 6 glaze and refired the bowl. The result was a glaze that slipped 2
inches from the rim, and resulted in a very uneven lichen type glaze to be
charitable .I will try this with one of Conrad's recipes and see what
happens. Ababi had you ever tried the dry engobe recipe yourself? I think
there is just too much borax in it for a cone 6 firing
I also tried some of her glaze recipes, and was equally disappointed by
the results .Each to his own taste. Mia in ABQ

Dear Mia!
I never offer something I don`t do myself! Actually what you described
happened sometimes to me.
The short answer is:Test test test!
The long one is: this in-between engob is rich with borax, a terrible
material! Does not melt and you cannot control it too much. But on the other
side, gives you an unpredictable result. Do not throw that piece, cover it
again and dry it, may be this time add a ^04 glaze and refire .I think if
you read the part of lichen glazes in her book(I know you have done it) you
will understand the "philosophy behind this techninq.I add here a recipe I
made myself, NOT TESTED!!!!!!!!!!!! to create more controlled "in-between
engob"
In between
======================
KAOLIN...... 53.55 53.55%
SILICA.............. 25.03 25.03%
FRIT 3110........... 10.71 10.71%
FRIT 3134........... 10.71 10.71%
========
100.00
Notes:
Based on Lana's engob. I changed because of the hard working with the
borax. Has to be tested.It has less B2O3, but I hope it does not
matter.actually THE FRIT IS A GOOD GLUE
As we say in Latin: From our success we earn money and from our failures we
earn knowledge

Mia,
I have the same problem with food recipes. Just because they work in
someone elses kitchen, doesn't mean they will work in mine. Some times I
have to adjust the cooking time/temperature a little or maybe it is the 10
year old baking soda I use. In the pottery, I can even get my shino glaze
to run, if I put it over the rutile glaze that I use a lot.
Keep trying, keep learning. A motto to live by.

Hi, I have the Lana Wilson book and so far have found several recipes in it
that I really like, it takes a lot of testing though. I hadn't used the
engobe until it was suggested on Clayart. My most recent project of empty
bowls with special needs kids and "at risk" 9th graders produced some really
disatrous results with the glaze. Even though I gave them my best "less is
more" speech on glazing, some students wanted to glaze with every glaze on
one bowl. This produced a lot of crawling. I experimented with the engobe
as a last resort on some really awful bowls. We bisqued the engobe to cone
05 and then reglazed. Our clay is a cone 05 to 1 low fire white. The
teachers didn't want to use commercial glazes so I came up with some cone 1
glazes. I used a simple cone 1 recipe with copper carb for the second glaze
with some really wonderful results. It did run quite a bit, but the bowls
were glazed all over the place anyway. I will need to grind off some of the
bumps at the bottom. Overall, I was really quite pleased with the results,
at cone 1. My next experiment will be cone 6.
Another really interesting glaze in the Lana Wilson book is the Persimmon.
First you fire it to cone 6, it looks like a honey amber, temoku kind of
thing, then you refire it to 05. I am not even going to tell you how
beautiful it turns out, you have to find out for yourself. Be careful though
at cone six it can be runny.
Best wishes, Nancy G.
