Babs Posted September 1, 2014 Report Share Posted September 1, 2014 Clay: Buy most but use locally sourced ie farm dam clay for self sometimes. Glazes: Mix Undrglaze/on glaze: Buy. Link to comment Share on other sites More sharing options...
Roberta12 Posted September 1, 2014 Report Share Posted September 1, 2014 Buy clay and mix glazes other than some underglazes and one color I haven't been able to quite replicate Roberta Link to comment Share on other sites More sharing options...

Callie Beller Diesel Posted September 2, 2014 Report Share Posted September 2, 2014 Clay: currently using premixed H570, but I have done both. I really liked to mix my own in college, when I had access to a Soldner mixer. It's a bit harder with a shovel. My supplier sells dry bags of premixed clay, for those who don't want to pay for freight on water. My favourite is a mix of H570 with 5-10% Redart for soda fire. Glazes: Make my own. I dig chemistry!

Babs Posted September 2, 2014 Report Share Posted September 2, 2014 Perhaps we now have to differentiate with the clay makers who dig clay and ones who mix dry clay prepared by companies .. Link to comment Share on other sites More sharing options...

That's why you would do something like this preliminary survey, with encouragement for expansion of the options, or a focus group to yield a more valid question form. For sure, it would be insightful to know how many people actually dig clay. Or alter a premade. And I'm noticing a pattern in the glaze mixers .... they buy certain types, like overglaze, underglaze, and resinous lusters, etc. Now I will be so bold as to ask "why" you mix your own glaze or clay? I'm asking these questions for my own skill development knowledge ... I don't sell any of these products. Thank you for your responses. Link to comment Share on other sites More sharing options...

Or of an age when premades were not available, but mostly because of hte curiousity and immense satisfaction which comes with the process. And you never know it all. ongoing learning, seeking. And I suppose the dollars though I've never compared the two methods. Link to comment Share on other sites More sharing options...

And I suppose the dollars though I've never compared the two methods. Or we buy the commercial glaze and it doesn't work with our clay/firing schedule/........ and want to improve it. Also the cost does come into it, Or, in my case, I was gifted a stack of buckets of raw materials and it seems daft not to use them....... Link to comment Share on other sites More sharing options...
Denice Posted September 2, 2014 Report Share Posted September 2, 2014 I fit into the age group when premix clays were not available and was thrilled when they became available. I still find myself making clay because I'm not happy with the premixed clay. I am also called a control freak or perfectionist now and then, I am glad to hear that's just one of the personality traits of a potter.

oldlady Posted September 2, 2014 Report Share Posted September 2, 2014 i guess i am just a leech. i buy readymade clay, use other people's glaze recipes and buy special stuff like red glaze for christmas items. i do try other colors in those glaze recipes, there are now 352 glaze tests hanging in the studio. oops, 7 or 8 of them are still cooling in the kiln right now and won't be hung for a few days while i mull over the results. who mentioned a test with crossing lines of glaze recently? not having the benefit of a college education, i am not familiar with what is supposed to be a basic tool for potters.

Babs Posted September 2, 2014 Report Share Posted September 2, 2014 A guy, Greg Daly has a great book on this, took the fear out of it for me, I haven't a college ed. in Ceramics either, just an enqiring mind, or obsessive, as I have been told at least once Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted September 2, 2014 Report Share Posted September 2, 2014 I prefer to mix because the premade stuff doesn't do what I want it to. I doctor a premade clay that has *most *of the characteristics I want, and add things like grog to improve its ability to "stand up" while throwing, and Red Art for flashing/colour. I'm currently away from a soda kiln, so it isn't as necessary, and I'm using premix. I mix my own glazes because it's what I was taught, so it's what I know to do. Even if I used commercial stuff, I think it would be useful to know how the chemistry worked. It helps with troubleshooting. And if I have to correct a glaze for crazing, I might has well mix it myself. Link to comment Share on other sites More sharing options...

If you're taking two glazes , A and B, together on a test tile, you lay down 4 stripes so you get a #. It tells you: -how the two glazes look with a single layer of each - a double layer of each -what glaze A looks like over glaze B -what glaze B looks like over glaze A (not always the same) -if either glaze or combination thereof flashes on the bare clay -if the combinations form a eutectic (excessively runny glaze) Link to comment Share on other sites More sharing options...
Babs Posted September 3, 2014 Report Share Posted September 3, 2014 One exercise Grag Daly offers is to take 2 of your known glazes and line blend them, then find a glaze from that exercise you would like to go on with and run similar tests with a variety of colourants. have done this and it is really interesting process. Knowong the chem is obviously the way to go. Am acquiring this thro reading and practising. Another of Greg's exercises is to take a known glaze and rotate the quantities of the chemicals methodically, say start with a glaze Pot Feld 40 Whiting 20 epk 35 Zinc ox 10 I made these up for this post! He then would try Pot Feld 20 Whiting 35 Epk 10 Zinc Oxide 40 And so on This way he says leads to truly different glazes which you would never have formulated.... Warning may need kiln wash and biscuits. Link to comment Share on other sites More sharing options...
Mudslinger Ceramics Posted September 4, 2014 Report Share Posted September 4, 2014 Mix my own clays for the sculptural work to get colour or effect 'just right' but buy commercial porcelaineous stoneware clay for the everyday domestic work as it will be covered by underglaze/glaze layer anyway.... saves me time Mostly use standard commercial pre mixed clear on the domestic ware which I modify for colour or effect sometimes, don't use any glaze on sculptural pieces as the clay texture and colour are part of the piece's 'voice'.

oldlady Posted September 4, 2014 Report Share Posted September 4, 2014 thank you diesel clay, maybe it is just very late after a long day but i do not see the result you suggest. vertical line glaze A, vertical line glaze B, horizontal line glaze A, horizontal line glaze B. got it right so far? OH!! got it. not quite. don't see how each crosses the other both ways. will think about this tomorrow, signed, Scarlett Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted September 4, 2014 Report Share Posted September 4, 2014 It's ok, I had to think about it a bunch to write the description You draw vertical line glaze A, vertical line glaze B, horizontal line glaze B, horizontal line glaze A. Then you get the over/under. Link to comment Share on other sites More sharing options...
