  1. Yes its a bit like stock trades-(I also do some of that as well)

    buy when price is low in quantity 

    Maybe the thing is decide if ceramics is your thing  and if that s a yes than approach materials in a business like manner .

    If you are just playing around  with clay than all this makes no sense.


  2. I think and this is a guess at this point in the foot ring needs to come out just a little and make them a bit thicker as well.

    I throw porcelain plates and fire at cone 10 without movement . I do have a small nubbin in center for slumping and they are thicker so they do not move-they are in my photo album if you want to see them.-

    At last weeks Art show I had 3  eight piece plate sets(glazes differently)  with salad plates-sold one set.They bought matching bowls in two sizes as well. Biggest sale at show for me. I tend to stock lots of dinnerware as most potters do not.

  3. Whats important is what can leach out of a glaze. That will depend on firing temps and clay body fusion and some other factors so if you sent your  ware in after firing it could test graet or poor and that whats most important .If its not leaching its fine.

    I use a baruim glaze at cone 10 and I use it on the outside (not on lip) so its a decratrive feature not on the functional part of pots.



  4. Materials have been going up especially lately. I stock/horde materials in larger quantities so am less affected by any fluxations . I also am a distributor so price hikes show up in email form from supplier every month or three  or six and I can see whats happening. Tin ,cobalt,frits and really many colorants rise (and sometimes fall ) fairly often. For example the world demand for cobalt /spodume in electric cars really drove prices sky high as Min said above .Other factors include larger companies buying up smaller mining companys and closing them down or taking all the supply for a few business like we saw with texas talc recently. This is a huge factor now in ceramics for us. It started about 10 years back and will affect us all. If one wants to avoid  this  some buy in larger quantities and shop around. I found a cobalt and odd colorant supplier(non ceramic supply)  who dealt in 50# lots and I bought colbalt carb and sold most of it so I would have cheaper cobalt myself. I bought  lots of Tin long ago during a drop in price cycle and will not need any more most likely.

    Trucking  cost has climbed steadily and adds to the prices. World demand also can make for rises. I have 8,450#s coming in a week (mostly porcelain) and share trucking to lower costs with our local ceramic supply house

    Every year almost I buy a few bags of  Alberta slip and silica, whiting and Nepheline Syenite  as I do not want to stock over 3 bags of each along with my clay order. These have all gone up but considering the price its been small and steady .Clay also has slowly risen.

    In 1982 I bought 3,000 of kingman feldspar and am down to about 200 -300#s now and that was a very good move it turned out. On a smaller scale one can do the same thing. 

    Now for hobbyists who only use tiny amounts you will take the brunt of all price hikes but really most things ceramic are pretty low cost.


  5. Yes wider foot ring

    If the plates are slumping because the foot ring is not supporting the curve (I cannot see in you photo what is going on) Then its a wider foot ring. If the foot ring is fine and the plates are trimmed to thin then its more clay. 

    You can decide or show us a bottom and top photo of the slumped plate looking down at it and I can see whats happening -I assume cone 10 as well?

    how wonderful for you!  being underwater with all those beautiful fish and all is a treat that you deserve.

    the third photo shows a fish with 4 mini-antlers on its head, do you know what it is?

    Thats a kelp greenling  in bottom photo and the fish above that is a sculpin and the nudibranch is aTriopha cataline

    I always either know the cruitter or key it out in my library of fish and Nudibranchs of the world books

    Glazing a vitrified pot is much more difficult than glazing a piece that is porous. If you're going to make a lot of pieces, you may find that the difficulty of doing it that way slows down production.

    This is a major point for any work that involes many pieces

    I suggest rethinking your firing strategy completely 

    Most ceramics is fired to bisque than glazed then fired to maturity.The reasons are ease of glazing and firing.

    So, I just can't get get those brass connectors ordered from Euclid. 

    My card apparently doesn't like the fact that the company is in Canada.

    Is there anywhere else to get those brass connectors, or would the stainless ones work as well?

    I had zero issues-call your card Company

    glad to hear that you have done so well at that show.   finally got word that a big one for me is going to happen on the street in alexandria.   now i can stop looking for small ones closer to my house and concentrate on having a huge amount of pots for october.  

    If the show happens(due to covid numbers on the rise) be prepared for big sales-consider marking your wares up a bit as well.

    I put out an extra table to distance ourselves andmasked all during the outdoor show hours. The public is super eager to buy right now. No telling about Oct. Thats my next show as well in NV. as well as a huge wholesale order

  10. WOW is all I can say abiut the show 

    I raised prices on 95% of forms . A few went way up.. Some smalls stayed the same. I packed van with every pot I could muster. The weather was a mixed bag with rain on fri early am then again most of  Saturday. Friday and Sunday dry. This show was the best ever for me not only at this venue but best in 47 years at any venue .The public is nuts on buying pottery and everything else  now as well. Most artist dis really well. Booths were spread out and I set up a extra table to keep customers at bay from us wrapping and selling.

    This is the same story all my other artist friends have said this summer about shows. The downside now is the virus is coming back hard in most places and at least in California outdoor events are being canceled right now in a huge way. I wore a mask for 3 days all day. About 1/2 the public is masked in Washington at this show and you can feel they want to be out but its degrading in the pacific nothwest as well as the rest of the country. My next show is the southern tip of Nevada state in early Oct-we shall see if this show happens outside in a windy park under a shade tree..It took a huge effort to keep my local venues stocked and do a show but I did both and it really paid off. It feels like time to hunker down again back home.

  11. It ius 100% a talisman  sieve. It the early modey . I have one exactly like that one. I also have two of the newer plastic models. They all take the same brushes.

    They had  when new a small foil stiker on them with name -and yours is long gone. I bought mine new at the time. I also have been to the talisman  business in New Zealand as well back in the 90s.Great producy on the right sink
