Posted 20 May 2013Jim,
I don't know if any of the earthenware suppliers for handcraft type potters are doing this, but an industrial trick to get the glaze on earthenware to go into slight compression (to prevent any crazing) is to deliberately add some of the cristoboalite form of silica into the body formulation. Because it has a very high COE... it helps the body shrink slightly MORE than the glaze (which without lead is typically dominated by hiogh COE alkaline fluxes) and keeps it from crazing. So if the glazing application is uniform and covers all of the clay........ no leaks.
This does not stop the absorbtion of moisture through unglazed areas like the rings of feet. Ot into things like pinholes and other such glaze defects. So microwave use after getting them wet is still potentially an issue.
That's very interesting. I was guessing that at lower temps it is much easier to get a glaze to fit the clay well enough to stop leaks. I've been around long enough to know stuff like this, but I don't: does terra sig stop leaks? That would solve the problem of the raw areas absorbing water.

QuoteLike Reservoir Dogs? That's just madness! What was the dispute over?
Not that dramatic. A neighbor hunting in my woods. I tell him to leave and he points a shotgun at me and I jump behind a tree and point my rifle at him. We were so far apart that his shotgun wouldn't have done much damage to me so I had all the advantage. It ended with him inviting me to swim in his new pool.... Gotta tell you this one, though, even though somebody's gonna say, "What the hell does this have to do with "Recommended Glazes?".... On the other side of our woods lived a big family (two double-wides full) of repo-people. For fun they shot beer cans off posts while riding their Harleys. They got all POed over me shooting one of their dogs gutting one of my goats and after a lot of arguing and threats we end up in court. I whisper to the judge that I don't want to take an oath that has anything to do with a Bible or some fantasy guy in the sky. The judge laughed and my neighbor and his wife went crazy thinking the judge and I were friends. I think he almost died right there, he turned so red and started sweating. I won and my neighbor was fined a couple of hundred dollars. I gave him the finger and walked out. A few days later my neighbor had a heart attack and died. He had 4 hardcore redneck, Harley-riding, repo-men sons and a wife who was meaner than any of them. I knew they'd say I killed their dad. So I had to carry a gun to my studio and couldn't leave my wife alone for a month or two until one of my llamas died near their house and I went down there and they came out and said, "We ain't mad at you no more. The meth's what really did him in, not you." One of them helped me drag the llama into the woods for the buzzards.
Posted 20 May 2013Today I had five people ask for 'honey pots'.
Ignoring the obvious smart-arse potential, I figured out that they meant 'medium sized jars with an aperture in the lid'.
I had none. Nor do I plan to make any. Oh well...
Many years ago when I was still doing shows, I had several queries about honey jars. After listening for a few years, and also having a request for a gift for a local guy that had bees, I made some. Many of the comments would mention that they would misplace the spoon/dauber or that they used them on the porch and bees or ants would be attracted even when the lid was on. I made some with these thoughts in mind, and sold great numbers of them. Over the years they have changed, but this example is one of the first years-a reject.
The newer jars, last two years, have a thrown hollow bulb on the end instead of the reversed handle shape. I then cut part of the bulb so that it becomes a spoon. Works a little better.
I never thought of making a spoon that way. Got a picture?
Sorry Jim, I don't off hand. However, consider throwing a tall thin goblet/chalice them, and instead of flaring the end, bulb it closing in completely. Then if you cut of one side of the bulb @1/3 of it you have a spoon for the honey. Some of these I have done to the opposite side of the opening, and put 1/4" hole to allow drizzling of the honey.
I will try that. Thanks very much for the tip.
Posted 20 May 2013I have only one mug in this load. I will let you know. As I recall, in working with this technique many years ago, they can retain water and as you say have a slowish type drip. They also respond unfavorably to acid type foods. So for example, you cannot put a bowl with say an acid based food in it for long periods or it can leach the glaze...I think.
Interesting. I guess you read what Mossyrock wrote. Have you tried the clay she uses?
