So I've been dabbling in glass as of late since clay is on hold due to atlanta clay being unable to obtain the raw materials I need. Mainly because of the weather. Fed up with that I was happy that axner has all I need. 600lb order coming Monday so im in need of space. Being I have a ton of low fire glazes from when I bought my kiln I'm now looking at ways to dispose of them. I've been successful with glass melts in plaster/silica molds and was curious about firing my glazes in them then turning around to crush them down for colored frit or even melt them into usable shapes. I know I might be getting into a mess of different co efficients. I did a test already but goofed and had a nasty over flow. I'd propose this to glass forum but have found they shy away once clay content is mentioned. Yet after a glaze is fired it is essential all glass correct? I would like to hear others opinions on my idea. Not recycling , nor disposing, but repurposing.
SO I recently fabricated a green house to tie into my pole barn where my studio is at. I guess I wasnt think thinking when if came to where my kiln room was at and where the exhaust would go. The arrow points to where my kiln is inside and the exhaust comes out from that area. I have a ventilation fan there to help with any fuming. I had worried recently that maybe the fumes might pose a danger even the green house is sealed to a point. The vent windows are on the far right wall which you can see in the photo. I have been wanting to use a dark cone 6 clay that contains Maganese Dioxide and I know the fumes are toxic. I was curious about if the position green house over all could present a danger? The green house will be for a aquaponics system where there will be an open fish tank and grow beds. Like I said the greenhouse is sealed in the sense that fuming really would have to try hard to get in. Still though I question could it pose a problem especially with growing edible food.
So here is where Im at now. I have stock of EPK, bentonite, red IO, and (being I live right next to a Mica Mine) access to mica. I know mica has little significance in a body, but I just like it for the flecks. From what Ive read I like what Wollastonite can do for both bodies and glazes so I would like that to be an addition to my body. My direction is more than likely going to be making tea pots or other vessels. SO I guess really Ive been searching for a recipe that would mature nicely at cone 6 and would hopefully have more character if it were to lack having a glaze.
The Bizen and Shigaraki bodies have such an attractiveness to them yet I doubt that can be attained at cone 6 in an electric kiln. Ive always liked how clays change their look the higher you fire, but Im only wanting to go as high as cone 6. I also have been falling in love with more iron rich clays and drifting away from the buff white clays.
I have rewritten this post multiple times and having trouble conveying what Im looking for...I think. So am I in the ball park?
Red Art (or red natural clay, low workability)
Red IO (maybe the addition for a darker clay)
Mica (if natural clay is not to be used)
Ball clay (if natural clay is to be used)
Red IO and Wollanstonite are fluxes right ? so keep their percentage at a maximum of 25 %? And the rest filler?
Last year some time I posted a thread about me adding dust and shavings from a hardware stores key maker. I had only fired to ^06 and it turned a typical dinnerware safe clear a deep green.
Thats the pic ^^^. So later down the road a few months ago I had some spare time and mixed some into Coyotes ^6 glaze to see what would happen. Results were better looking because I enjoyed the new white that showed up.
Im not looking into this to really delve deep. This stuff was just free and more of it is free. So why not enjoy some freebies. I know Im more than likely adding a bunch of flux to this glaze and it will just run a bit. But in the interest of formulating my own glaze I could have a chance to cure some of these issues. Like I said Im not making this a full time test, just curious. Although this curiosity leads me to question is adding key shavings (mainly copper or brass or a stitch of nickel) even fired to cone 6 potentially toxic? Ive read that their are some issues but also that there are no issues. Something I come to find a lot in this clay world. Opinions? Hearty discussion?
A while back I asked about some good books to have as a potter. i was given some good recommendation and over all ive enjoyed having mainly the Potters Dictionary. Yet, these days ive been drifting out of the pit fire world and trying to focus more on the functional. I would like to drift towards the Cone 6 world as many have. Really over all I want to learn more about making glazes. I hate myself to this day because I never spent enough time in the glaze room in college. So my question is what good books might be out there to lay out glaze making techniques? I can find a lot of stuff online and even some recipes, but really when it comes to seeing whats in them I dont know all the functions for each ingredient. Ive done a lot of research on different ingredients, but would really like to have a book or books to aid me. The potters dictionary is great but what else might be out there?
