smesa Posted February 3, 2021 Report Share Posted February 3, 2021 Thinking of leaving my marbled earthenware bowls raw on the outside and glaze the inside where food will touch. Is this ok for earthenware or will the outside absorb lots of water when it’s hand washed? Link to comment Share on other sites More sharing options...
oldlady Posted February 3, 2021 Report Share Posted February 3, 2021 water will dry but the oils in your hands and whatever might touch the surface will leave a residue. at the least, unattractive. Link to comment Share on other sites More sharing options...
smesa Posted February 3, 2021 Author Report Share Posted February 3, 2021 Oh I didn’t think of that, I wish glazed pottery could look as soft and natural as bisque Link to comment Share on other sites More sharing options...
oldlady Posted February 3, 2021 Report Share Posted February 3, 2021 it can look a little like that with the right glaze application. look for something in your firing range that is described as either matte or satin finish. the right glaze can make the pot comfortable to handle and sanitary.

Hulk Posted February 3, 2021 Report Share Posted February 3, 2021 Glazed on both sides should be considerably stronger as well... Link to comment Share on other sites More sharing options...
Rick Wise Posted February 3, 2021 Report Share Posted February 3, 2021 Especially look for glazes labeled "stoney matte". Link to comment Share on other sites More sharing options...
Sorcery Posted February 4, 2021 Report Share Posted February 4, 2021 I would do it. Nothing wrong with a little patina. I was researching some glazes the other day and found this.

Babs Posted February 4, 2021 Report Share Posted February 4, 2021 @Bill Kielbhas a clear satin matte may be a good starting point. Link to comment Share on other sites More sharing options...

I do like the look of these in particular but with marbled clays I may enjoy them more if they stay the colors they are. Thank you for sharing this technique, I will definitely try it on some other pieces Link to comment Share on other sites More sharing options...
Min Posted February 5, 2021 Report Share Posted February 5, 2021 It's hard to tell from the images @Sorcery posted whether or not those cups are glazed both inside and out or not. Couldn't find any information on the linked website. They could be glazed and from either crazing or underfiring the glaze they have acquired a patina / staining with use. @smesa, if you do decide to only use a liner glaze and leave the outside of the pots unglazed you run the risk of the pots dunting (a crack through the glaze and body of the pot) unless the glaze is an extremely good fit to the body it's on. Other issue with only using a liner glaze on earthenware is the porosity one. It won't take long for the clay to take up water from doing the washing up etc. The pots will get extremely hot in the microwave as the damp claybody heats up. Delayed crazing is very likely going to happen. Any oils, fats etc that are used in the pots will enter the body and cause rancidity as they can't be effectively washed out of the claybody. If you do want to only use a liner glaze I would suggest using claybodies that have close to zero porosity and do some testing to check for very good glaze fit so the pots don't dunt.

I took your advice and glazed them with a matte clear glaze. Wow! The soft bisque colors stayed put. Thank you Link to comment Share on other sites More sharing options...
oldlady Posted February 6, 2021 Report Share Posted February 6, 2021 glad you like them. now to find out if the glaze is durable for use. btw, use only 3 posts for your kiln shelves so they stay level and more stable. Link to comment Share on other sites More sharing options...

Chilly Posted February 6, 2021 Report Share Posted February 6, 2021 And use fewer posts, leaving some spare for more shelves. Link to comment Share on other sites More sharing options...

Had no idea! I always thought 4 was safer for keeping it leveled. Will give 3 a try next time thanks Link to comment Share on other sites More sharing options...

Not so thin that it does not adequately cover, just the thicker one gets with any clear then more coloration and cloudiness is likely. Link to comment Share on other sites More sharing options...
