One of my favorite pots

[Brian Van Fleet]

Awesome! First generation? Congratz on your birthday by the way!

Thanks, yes, first generation.

What's the size on this one?

3”w x 2”h

New pickup some of the resident “potheads” may enjoy...

Very cool!! Ok, this much be a special Tofu Sr pot, what with all the extra stamps. I hate to say that I've never seen one like this.

I get the feeling he had a good sense of humor. It is decorated with 25 stamps. Some fairly rare, cool pot.

Ahh sorry about the late replies. I see a post on my phone then need to remind myself to reply later.

Wondered who got that one- nice score

I was honestly surprised it was available when I looked and knew it wouldn't be if I waited. It's a cool pot, my first dragon and it has the real fun aspect to it.

Sweeet! Is that the mudman from the same release? Nice pickup!

Yeah that was something different, he's just chillin on the shelf overseeing some pots and books.

That is one of the coolest pots I've ever seen. My wife would dig it because she has a thing for frogs. I found this one by Marcus Berenbrinker through Harry Harrington's site:

Just picked up this cool matte gold Roy Minarai oval from Mirai. It's not a typical glaze for Roy, but still plenty of visual interest. It was reasonably priced (to me) compared to a lot of their other stuff so I snatched it up. I think it would pair great with something like a silverberry with its rusty-colored leaves. Always happy to add to my collection of Roy pots! Photo credit goes to Mirai (I cropped it to zoom in a little).

This is one of my oldest pots. A Kinka pot with a chip on its shoulder.


P.S. Does anyone have the solution for cleaning antique pots? The residue never seems to go away.

The old school solution is to bury them in the ground for a couple of years. The mineral deposits break down and release in the soil. I have soaked old mid range pots in CLR with good results. Would not advise with expensive antiques though.
PS: good idea to remember where you bury them!

Have you done this with any success?

I have not buried them in the ground myself, the suggestion to do so came from my teacher and has been repeated to my by other professionals i have asked. I have been told it can take up to a couple of years being buried. I would imagine the time involved would vary with the PH of the soil and i suspect it may not even work in Alkalai soil.
I do not have the desire to bury my best pots for a couple of years to test it out.
I have had good success with CLR on mid range pots. i have not tried on expensive pots for fear of messing with the patina.

Every time someone suggests “bury it in the ground” to clean calcium deposits off pots, I ask if they had done it. So far, every time the answer has been no. So I tried it once for a year with one pot. Rather unscientific, but tried nonetheless:

Glad to hear it has worked for you. I was thinking that an acidic soil would be most effective. We have a patch that we use for composting all the household scraps. It gets turned pretty often so one corner would have to be carefully marked to avoid shovel marks. I will start one today in the scientific interest of repeatable results. Who knows, perhaps it only works in soil made in the USA and Japan The chosen subject is a Tokoname, Yamaaki Toshio. 37cm by 25 cm, 9.5 cm high. The stains mar the feet and bottom of the pot.
The other reason for marking the spot and recording for posterity is my advancing age! However i am informed that is the best alternative
The pot is buried and the soil thoroughly watered, no fertiliser at this point as it is a very recent transplant. We are entering the rainy season so i will check it in the spring for progress.

The idea behind baking soda + vinegar is that first the acetic acid releases the oxygen from the salt, and then make it bond with the releasing CO2 from the sodium bicarbonate or with the leftover part of the acetic acid (thats how sodium acetate can be made, used in banana oil).. Which in the end will form rock hard carbonated crystals. This time sodium carbonate, potassium carbonate and possibly some other salts. It's how people make crystals, not how one should remove them. I never understood that process.

The deposits are oxides from minerals, not just calcium, but also magnesium and various nutrients. If these nutrients are in the metal-group of the periodic system, a soak in demineralized water with household dishwashing detergent would work well. A dash of coca cola or pepsi (phosphoric acid), whichever you don't like, will aid the EDTA in the detergent to pick up those minerals and keep them in solution.
It speeds up the process quite a bit more. Demineralized water can hold a lot more ions than tap water.
It might take a month, maybe a change of solution too, but I think it would work faster than burying them.

I'll see if I can find some mineral deposits on some old clay pots and test this theory. I don't have any glazed pots with those deposits, but if anyone wants me to test those, just ship them over!

Sort of a chemical reverse osmosis. I like it, my choice for the additive is Pepsi would be a waste of coke!
The Phosphoric acid is pretty strong, i have used it for concrete cleanup and also lowering the PH of water supplies for Aquarium use! Would you expect any effect on the baked clay?

I did it with an older Koyo glazed pot... buried in the back yard garden for 18 months and did absolutely nothing.

It depends a lot on the clay type. If your clay is very high in mineral content, it might become a little more porous. But, with the addition of new mineral deposits over time, it might be not that much of an issue since those dissolved minerals would be replaced pretty fast.
Also, we're using just a dash of pepsi, maybe half a can in a bucket of water. Which should lower the pH of a bucket of water with just a few points. Maybe to around pH 4 or 5-ish, maybe just 6.5. In concrete cleanup, one should use at least 10-30% vol. of acid. Which has a pH around 1 or even lower. The pH scale is imaginary, is goes from 1-14 but actual values can be a lot higher and a lot lower in very alkaline or very concentrated solutions.
A glaze shouldn't be affected, since that's silicium-based (as far as my limited pottery knowledge goes) which shouldn't be affected a lot by acids.

I have done it several times. The thing is, it takes time, like a couple of years, to be effective. Burying the pot for a month or two isn't going to do much. Six months either.
