Local clay ok for funtional ware?

14 September 2011 - 10:15 AM

Hey everyone,

Quick question. I harvested a large amount of clay from a bank near my home and it is finally all processed and ready to work with! But now I am debating what to make with it. I want to make some functional pieces with it and have been asked to make a mug from it for a friend. If glazed with lead free will these wares be safe for kitchen type pieces and also what are some things you would check or test when harvesting local clay. I have tested firing temp, and shrinkage already but am curious about what else I need to look into.

Thanks

Glaze Cracking pre fire?

31 August 2011 - 02:41 PM

Hey everyone,

Quick question. I glazed some stoneware with ^5 glazes most of which look ok but a few of the first ones I did appeared to be cracking (the glaze not the ware) so I added more water to the mix and it seemed to help. My question is what can I do about the pots with the thick glaze i can crack it off with my fingers. Should I just wash them with a sponge and re-glaze or am I stuck. I'm holding off on firing them because I am assuming the glaze will run because the original mix was to thick.

Thanks,
Anthony

Low fire clay and functionality

25 August 2011 - 10:06 AM

Hey everybody,

I have come across a large amount of cone 06 white clay and was wondering if glazed with low fire 06 lead free glaze if this clay can be used for functional ware as well. To date all of my experience with functional ware has been with cone 6 stoneware and cone 6 glazes. So is this clay practical for that use as well or should I just plan on making decorative and raku ware with it?

Thanks

Terra Sig on Functional Ware?

09 August 2011 - 02:33 PM

Hello everyone,

I was reading that terra sigilatta when applied to greenware and bisqued will seal the pot thus eliminating the need for further glazing. Is this true and if so is it possible then to terra sig stoneware in a similar fashion as Greek and Roman pots and then use them for functional ware such as mugs and pitchers? I have been researching red terra sigs and love the organic/ancient look achieved with them and would like to make some kitchen ware using this method. Any advise is greatly appreciated.

Thanks

Any one know where to find a metal bat for a Randal Wheel

07 August 2011 - 11:16 PM

Hey everyone here is my dilemma,

I purchased a Randal Wheel several months ago and it came with 3 plaster bats. All of which work fine but are a little beat up. I took a ceramics course last summer at the university and we used the same wheels but they had metal bats which were much easier to work on. I spoke with the professor who said the company that makes them is not around any more. Does any one know where to find metal bats to fit this wheel, do they tend to be universal or do certain wheels require certain bats? Just got in to ceramics about a year ago and I love it their is so much to do and learn it seems infinite. Any advice is appreciated.

Thanks,
Anthony

I attached a picture of the wheel below as well.
