cstovin reacted to Min in Using Red Iron Oxide with Regular Glaze
I wouldn't recommend doing this on surfaces that come in contact with food. Not because of food safe issues but because using cutlery on an unglazed surface is going to be unpleasant. The washes I posted leave a deposit in the nooks and crannies but they are not a glaze. The clay itself will show where the wash is wiped off. I would suggest using as clay that is as vitrified as possible so over time it doesn't stain from coffee dribbles etc. ie, use a body that has as close to zero absorption as you can find.

Ceramics= pretty much anything made of clay materials. Technically, anything made from aluminosilicates.
Pottery is ceramic. Little figurines are ceramic. The porcelain parts of spark plugs are ceramic. Knife blades can be ceramic. Toilets and sinks are ceramic. Tiles are ceramic. The slip cast figurine branch of ceramics has taken the term to mean what they do, and call things made with moist clay 'pottery'. People who work in figurine ceramics are the only ones who use the term 'ceramics' they way they do. Everyone else uses the much broader definition of the word. If you read the magazine 'Ceramics Monthly', there are no slip cast figurines in there. It is all potters and sculptors. Some of the work may be slip cast or made in molds, but they create their own molds from scratch.
It can all be fired the same way. There's a lot of mis-information in the figurine ceramics world about what potters do, simply because figurine 'ceramics' folks don't make pottery.

Definitions according to the internet:
Ceramics = pots and other articles made from clay hardened by heat.
Pottery = made by forming a clay body into objects of a required shape and heating them to high temperatures in a kiln which removes all the water from the clay, which induces reactions that lead to permanent changes including increasing their strength and hardening and setting their shape.
As far as the firing goes: there is no truth to that statement, many people here fire to cone 6 in under 8 hours. I know I used to run a schedule that fired to cone 6 in 7 hours.
Ceramics = Pottery. There are those who separate themselves from potters, sometimes calling themselves ceramic artist, but in truth all potters are also ceramic artist. It is just how fancy we want to sound when we say our title.
cstovin got a reaction from Callie Beller Diesel in Newbie Needs Help With Glaze Cone 6 - Can It Really Be This Hard?
Thank you all; I didn't necessarily mean a three ingredient glaze would be "easy", but easier in terms of only three ingredients to potentially trouble shoot, and much less to spend at first
I liked the comment about cheating lol
Thank you for suggesting it go on heavier, I thought the second time around two coats would be good; and I did mix it with a little less water but will try it again

Thank you, PomPots, I will get my questions together and post them.....most of the items I do now are decorative, so crazing isn't too much of a concern for me now; but I just wanted to get more information and can't find much! Will try the search terms you suggested also -
