#93050 Success

Posted by Chantay on 22 September 2015 - 02:39 PM

It only took 18 months (part-time) for me to learn about glazes and how to manipulate them to get results I want.  I have read so much about glaze chemistry I feel like my head is going to exploded.  For beginners I can't say enough about how helpful John Britts book, The Complete Guide to Mid-Range Glazes was.


I want to thank everyone here at CAD for all your help also.  So many great things have come out of this last firing even having over fired.


I am posting just one of the glazes I have come up with.


I replaced pic with a smaller one.

#93049 New Smell With Firing

Posted by Chantay on 22 September 2015 - 02:29 PM

Thanks everyone for the replies.


I looked the vent over and found nothing broken or out of place. I have decided that the smell was due to a lack of air flow plus the increase in organics.  Half of the Alberta slip was calcined but still to much organics.  During the firing at around 1100F I slid a plug partly out to let a little more air in.  The smell immediately improved.  By the time the kiln hit 1500F the smell was gone.  I don't have a hole in my kiln.  I have a homemade exhaust vent that uses the bottom plug hole with a modified plug.  It has worked great till this firing.  This is the first firing I have had 2/3 of the pots with the alberta slip glaze.


Planning on moving again in the near future.  Will plan to modify vent at that time with a hole in the bottom for vent exhaust.

#92937 Porcelain On Other Clay

Posted by Chantay on 20 September 2015 - 04:26 PM

I do this frequently. I can't think of the name of the porcelain. I put it over red rock. I have had success at any point before leather hard.

Marcie, I just read today that to calcine a material it only needs to be fired to cone 022, 1000 degrees.

Your Rocking It! Those pots look great. I always think the freshly thrown red clay looks sexy.😁

#88686 Glazes With Alberta Slip

Posted by Chantay on 10 July 2015 - 09:49 PM

I couldn't be happier with the results of the glaze testing I did last week.  I have been looking for glazes that work well over standard's Red rock.  It's a red cone 6 clay that is a joy to throw with.  I will attach pictures of test tiles which should show the name of the glaze on the picture.  If anyone is interested in these glazes they are available on the Plainsman clay website.  The Alberta Slip Rutile is suppose to be a substitute glaze for a traditional Rutile blue.  These were all fired in a regular firing sequence without any hold or long cool down.  The Alberta Slip Rutile should give an even more Hares Fur Blue in a slow cooling cycle.

#88493 Looking For Honey Colored Slipware Galze Cone 6

Posted by Chantay on 07 July 2015 - 06:48 PM

Wow, thanks everyone.  Great response.  I will try both glazes.  when I try the glaze from Fetish Ghost I will reduce the RIO, then also try it with the RIO and Manganese Dioxide that Adrift Pottery uses.  I like to try three or four similar glazes before deciding on one. I also test with varying amounts of colorants.  It is amazing at the variations.  A glaze like this I will use alone.  But I normally take into consideration how  a glaze works with the other glazes I already use.  After testing 6 clears there was really only one that would work.  Two crazed, two wouldn't work over underglaze, one wouldn't work with colorant, etc.... I could use two or three clears, buy why when you have one that does it all.  I was really surprised by the number that crazed when the slightest bit to thick.


Babs, thanks for the hint about the sodium.  I was hesitant to add any as after it is mixed and sieved I divide it.  Part will be just for slipping the outside of red stoneware, Part will be for a thick, creamy, decorative finish.  I want to make some cups that look like they have frosting spread over them or folded fabric. 

#88413 Glazes With Alberta Slip

Posted by Chantay on 06 July 2015 - 05:09 PM

Posting an Update.


Got up at 2 am and started kiln this morning.  Will unload tomorrow morning and hopefully post some pictures soon after.  Ended up making over 120 test tiles.  Using 8 different glazes, made tiles with each glaze over than under the other seven glazes on both a white stoneware and red stoneware.  Didn't have enough dishes to put under all the tiles that I was unsure of in regards to running.  It was time to put kiln wash on the shelves again so I added a couple of extra coats in case of drips.  Part of the delay has been the crazy weather.  We have been having a chance of thunderstorms (and usually getting one) for nearly every day for two weeks.  I wont start the kiln if there is a chance of a thunderstorm.  About 50% of the time I loose power when there is thunder and lighting.  After 5 years of lower than average rainfall we are making up for it this year.  I plan to have some pictures done on Wednesday and will probably post some that night. 

#87768 Feel Like I Am Hitting A Brick Wall - Perhaps You Have Experienced This?

Posted by Chantay on 25 June 2015 - 11:58 PM

This has been a wonderful and inspiring thread. Such good advice for experience and wisdom. Funny how so many of use are in the same position. I am recently divorced. Last summer, knowing what was coming, I worked very hard to improve my skills. I threw and recycled the same 200 lbs. of clay about 8 times. I was throwing several hours a day, 7 days a week. By November I took my 3 kids and left. It has been a real struggle. Making glazes has turned out to be more difficult than I imagine. But I'm home when the kids walk in. Even though I'm working a lot, we couldn't be happier. Things will improve in Oct. My girl/boy twins, 16 will get their drivers license and the 14 yo.will be able to walk to school.

You will get over this bump and figure out, even if slowly coming,how to manage it all. I'm just grateful to be able to throw clay for a living, even if it's the same blue bowls and mugs, and not have to drive into the city to sit in a dreary office behind a desk.

Side note, my kids help a lot to make things work. They take turns with me fixing dinner, do their own laundry, help each other with homework, have chores like feed the dog, empty dishwasher, take out the trash, etc. Kids can usually rise up to the occasion when expected to do so. If you explain to your kids, that if helped around the house, to free you to work, you won't have to work outside the home, they may rise to the occasion. Good luck.

So was sweating in the studio. Mixed up 5 glaze test, then the power went out. I would consider mustering on with my headlamp on but my son took it to camp. (Weary sigh). So sitting in the dark with my phone and a beer, watching the lightning and listening to the thunder.

Of course mine is very different. I use a surgical blade to cut the clay, he uses a mear box cutter. Sniff, sniff. ( You may return to your non-sarcastic discussion now.)

#87412 "i'm In A Spot Now Where Demand Exceeds Supply"

Posted by Chantay on 19 June 2015 - 12:04 AM

You two are a true inspiration.I was telling my kids about you both in a general sort of way. Explaining how hard work with the motivation to learn the necessary skills, in your case how to run a business and sell your product, lead to your success.

Now, I could say a few snarky comments about the current situation with politicians and our government, but I won't. I'm trying to keep my blood pressure down.

A bad day in the studio is still better than a good day behind a desk.

#87082 $40 "envirovent" For Electric Kiln

Posted by Chantay on 13 June 2015 - 03:49 PM

Mine cost about $80. You must of got a better deal on the fan. Looks same as mine. I didn't want to drill holes in the bottom of my kiln. I drilled holes in the bottom peep. Then using a coat hanger suspended the flexible vent hose from the peep directly above. The fan is strong enough that the vent hose is pulled against the outside of the kiln by negative pressure. There is enough air drawn though the crack at the lid for good flow. I did add some holes to the vent hose before the fan to ensure it was cool enough. As the fan ages I can go back and cover them to maintain a good draft.

#86664 Can Anyone Suggest A Glaze To Match The One In This Photo?

Posted by Chantay on 07 June 2015 - 11:39 AM

Diesel Clay,


Thanks for the link.  I have been looking for something like the Alberta slip glaze for my red stone ware.  Going to give it a try.  Although it is kinda pricey.  The Alberta clay locally is $132 for 44 lbs.

When using a new untested glaze I use small flat plates that I put kiln wash on to prevent drips on the shelf.  The are reusable numerous times.
