Ceramics Insider Tip - Semantics in Ceramics
It has come to our attention that many new ceramists are
confused by some of the words in our 'ceramics language'. They think applying a
clear glaze over an underglaze is using an overglaze. Or they think they need
to apply clear glaze over a colored glaze to 'finish' it. We thought we would
try to help clear up the confusion and help everyone understand how important
it is to use the proper words when asking for help with a
product.
Underglaze - Painted on greenware or bisque, this product goes
UNDER the glaze, hence the name underglaze.
On greenware the piece must be
fired to cone 04 before glazing.
On bisque, apply clear glaze over the
underglaze and fire to 06.
Glaze - Painted on bisque either on its own or over an underglaze.
This can be a colored glaze covering an entire piece of bisque or a clear glaze
covering an underglaze. After application glaze is fired to cone 06. Clear
glaze is called clear glaze, not overglaze!
Overglaze - This is a
special third fire product, which is applied OVER your fired glazed ceramic
item. You should not apply Mother of Pearl or fired Gold over unglazed bisque.
Overglazes fire to a cooler cone temperature than glazes fire to. The cone used
varies with the product.
It is so simple once you know - underglaze
goes under a glaze, as the name implies. Glaze is applied to bisque. Overglaze
is a special product that is applied over your fired glaze then fired to a
special lower cone. .
If you have any questions about other confusing ceramic words, or if this didn't clear it up for you, please let us know and we'll include the explanation in a future newsletter.
Hard Spots - Follow-up
Here is one response to our Hard Spots question from last month -
I believe from experience that hard spots are created in the casting of the greenware from pouring too fast on one spot on the inside part of the mold; from sanding wet greenware; from handcream; from holding leatherhard greenware too hard with fingers. For fixing hardspots on greenware I will wet the hardspot quite a lot and then apply several thinned down coats of liquid slip with a soft haired brush. When totally dry I will then lightly sand the spot with a very fine (wornout) sander. I used to use just vinegar and water but I found better results from the above method...fool proof. Hardspots on bisque, if acrylics are to be used, can be sprayed with a porcelain type spray. If glaze is to be used, try laying the glaze on gently and let it dry totally before applying the second and or third coats. Just my opinion though..............Kathy Joyal
