Dear Clayarters:
Please could you help me.
I am fatally attracted to majolica, but after I returned to it, after
5 years, I realized why I abandoned it: pinholes!
Could anyone answer these questions?
Does pinholing occur because of too fast firing or slowing down?
(I fired to 04 on medium with my controller.Kiln cooled in 24
hours
but after the firing finishes it cools very rapidly)
Can I refire to get rid of said pinholes?
Would a commercial glaze work better? Or is a comm.glaze prohibitively
expensive?
Does anyone have experience using Stroke and Coat as majolica colors?
Because I noticed that where the color was thick (on the edges of a brush
stroke for instance) there was crawling of the glaze.Otherwise it seems
these colors are ideal for majolica.
Does anyone have a recipe for a cone 6 majolica? Or cone 4?
TIA,
Sharon

Sharon,
Its not as easy as it looks. 24 hr. is more than enough. like anything
in this area you have a number of things to consider. I fire to the same
temp. in about 12 hr. I make sure to take 6 hrs. from 500 degrees F up
to about 1100 with the lid proped 1/2 in. up to 500 and the top spys out
from 500 to 1100. I fire green glazed and bisqued ware this way. Hope
it helps.

Did you add starch to your mason stains mixed with frit? Most of my recipes
fire better at 03. What type of brushes are you using and how do you stroke?
Are you sanding the pot with your hand after dipping? What clay body are you
using? Remember Majolica came about as European potters wanted to imitate
Chinese porcelain, (although the technique was brought to Europe by the
Moors) it was design to fit over terracotta

Check the clay art archives a few weeks ago Majolica was the hot subject.

I am not using mason stains, but commercial stroke and coat underglazes.
Yes, I sand w/my hand. I am using white (Laguna earthenware) - My majolica
fits it very well. I believe my problems are in the bisquing (too low)
and the firing. This time I want to persevere and get it.S

Another possible alternative...the march 97 issue of Ceramics Monthly had
recipes for engobes by Wayne Bates. you may want to check out his work. the
article had several color pictures to give you an idea of the effects he
achieved.

I too am fatally attracted to Majolica. I have (sorta) solved the pin hole
problem by rubbing over the entire piece of raw glazed ware. When firing the
kiln I "soak" it for at least an hour at the maturing rate (cone o4) of the
glaze. Has helped a great deal. Hope this helps you.

I think it's the soaking that does it. I've got a kiln to unload tomorrow,
that I soaked for 5 hours, We'll see....

I had a pin hole problem that I asked Pete Pinnell about. He suggested
soaking for about 30 minutes before the frit in the glaze melts. I use
Ferro Frit 3124. I soak at 1350 degrees F. for 30 minutes and have had
no more problems with pin holes or freckles. Hope this works for you.

The soaking may be necessary for one glaze, but not for others. I have =
rarely
soaked more than 30 minutes and after firing hundreds of glazes at cone 6 =
have
few pinholing problems. I had more problems at cone five.

I fired at cone six for five years and found that my glazes liked a good
30-60 minute soak or many of them would pinhole. But then, I like rutile
glazes and they are known to pinhole. Soaking usually took care of the
problem.
Several years ago when I made my first foray into majolica, I tried Linda
Arbuckle's majolica recipe and emailed Linda to ask if she soaked her 04/03
recipe (check out her article at the ceramicsWeb, it's awesome-
http://apple.sdsu.edu/ceramicsweb/articles/majolica.html and the recipes
http://apple.sdsu.edu/ceramicsweb/articles/arbucklemajolica.html )
She told me she doesn't soak her majolica and so I never did and I have
never had any pinholing problems with that glaze. Perhaps the pinholing
problem someone reported was not firing the earthenware clay high enough in
the bisque?
YMMV :)
Mishy, who realizes this dates her online life ;-)

Lorca -
I tend to be a bit of a stickler about historical information, but I try to
do so in the name of constructive spread of information. Tin-glazed
earthenware originated in the Middle East before the Chinese were making
porcelain, and it spread with Islam across North Africa, and as you point
out, into Europe. But it was a circuitous route. Hispano-Moresque ceramics
spread to Italy via the island of Mallorca, and in Italy the name evolved to
maiolica. As was mentioned several weeks ago, the tin-glaze process with
overglaze colors moved into Europe via Faenza, and thus the French called it
faience. In most European countries faience was referred to by the places
it was made, so in Holland it is Delft, in Germany Hannau, in England
Bristol and Lambeth, etc, etc.
Once Chinese porcelain began to appear in the west, both the Middle Eastern
Islamic potters and the European potters began immitating it in faience (and
the Islamic potters did a far better job of this than the Europeans did),
but it is not really correct to say that Maiolica immitated Chinese
porcelain, because the Italians did so only very rarely, especially in 14th
and 15th century maiolica.

Vince:
Thank You for correcting me, I have read a great deal on Majolica, Delftware,
faence, etc...I got this information from a book on majolica, I'll have to
back track and find out where I got this source of mis-information from, this
new information sheds a whole different light on the subject, and busts apart
alot of my theories on postmodern appropriations before postmodernism was ever
invented....I'm kinda of a majolica nut, so if you could refere me to more
reading or suggest collections to look up I'd really appreciate it ...
