Yeah, the change that our grandparents saw in their lives is nothing compared to what we have seen. I say that not using parent, because at 90 my Dad is still alive. . . just drove his motorhome up from Florida. He does not use a smart phone either, whereas I do, just don't use it for a whole lot other than text and phone. I do have wonderful level app on it though that comes in handy often .

As promised:

 

    1. 1. c. Mirror: Similarly, the clay you've prepared should be nearby and kept covered with plastic at all times. The wire tool can dangle from the splash pan, while the chamois leather hangs over the edge of the water bucket. I also find it helpful to have some kind of a gauge (like the sponge stick on page 25) and a mirror (see page 65).

      2. c. vitreous: In its simplest form, engobe is little more than a creamy slip, like the slurry you remove from a thrown pot before you take it off the wheel (which is why many potters refer to engobe as “slip”). The difference between the two is mainly the amount of non-plastic (not for throwing) materials in the mixture. In the right proportions, a fluxing (melting) agent and other ingredients make the engobe more vitreous. (The more vitreous an engobe is, the more it resembles a glaze.) Engobe can be used to decorate a pot from the time it’s freshly thrown and still on the wheel to when it’s almost dry.

      3. d. sgraffito: In Italian, sgraffito means "scratch." In pottery, you scratch through one or more layers of material, exposing what's underneath. One of the more appealing aspects of sgraffito is the immediacy with which you can achieve imagery.

      4. c. On-glaze, In-glaze: On-glaze colorants are mixtures of coloring oxides, flux, and sometimes a bit of clay to help flow and adhesion. These ceramic “paints” are usually mixed to a slightly more watery consistency than glaze because they are applied right on top of an unfired layer of glaze. The fired effect of on-glaze colorants usually looks more ethereal than that of an engobe or underglaze. (The engobe or underglaze is applied underneath a clear glaze, resulting in sharper detail. An on-glaze colorant melts outward into the layer of glaze, and is blurrier.)  Of note here, for those of you that are looking for In-glaze in the text. I added In-glaze, as I did not know if all would no On-glaze. In-glaze is a term I have used and read in other texts describing the same process. If this confused anyone, my apologies. . as I added it to help those who were not familiar with On-glaze.

 

I truly hope that folks are reading the full answers, even if you know the answer. Furthering understanding is part of the process, and a nudge/reminder can help us to remember something we know, but forgot or have discarded.

Sometimes you just have to take your best guess, the information is in a lot of other sources now days. The Bailey, came out just a little before the Hesselberth and Roy, I believe. At least that is the way they appeared in my library.

The better question: the grid goes down for a year and the battery on your cell phone is dead in 24 hours: now what?

Solar battery charger. . . don't you have one nerd?

Hmmm, guess if you only miss one that is 75%. That is pretty rough. Sure you don't want to pull that old Bailey out? :unsure:
