#117328 New Teacher ..help!

Posted by Celia UK on 27 November 2016 - 07:05 PM

My advice would be to make some 'damp boxes' to store pieces from one week to the next. Large, lidded plastic box with about a 1" thick layer of plaster in the bottom. Several of these can stack and the work can be stored for weeks without drying out. Saves all that wrapping in polythene and spraying - I only discovered these after I retired from teaching and wished I'd known about them before. I have several in my home studio so I don't have to worry about pieces drying out before I can get back to finishing them. Google 'magic box for clay' and/or Tim See for YouTube video showing how to make.
Red/brown earthenware is a nightmare to clean up and stains everything! I'd stick to clay if I were you.
You definitely need some one session projects so that the students get to see results quickly - certainly in the beginning! It keeps them interested if they get to see a finished pieces quite quickly initially. They'll be happier to take longer over subsequent projects.

Try every idea out yourself first - you'll work out the difficulties in advance AND have a finished product as a teaching aid and motivator for the students! Have an 'extension' activity/idea up your sleeve for students who whizz through at a record pace - there's always one!
Don't underestimate the time it takes to clear up - get the students into good habits and be a good timekeeper yourself, otherwise you'll spend more time clearing up than you do teaching!

Agree with the 'candling' in the kiln suggested above. The one and only time I had work 'explode' in the kiln was because I'd been in too much of a hurry and a piece wasn't completely dry.
Good luck and enjoy!

#114639 Qotw: Ceramics In Action Pictures Anybody?

Posted by Celia UK on 13 October 2016 - 01:54 AM

I don't generally consider my pots to be functional because of the way I alter them - cut, distort, carve holes etc. but a friend sent me this photo of two pieces she won as prizes at the golf club. Quite ingenious to use plants that grow in gravel I thought!

#114212 White Stoneware Low Fire Glaze Mistake - Pinging

Posted by Celia UK on 03 October 2016 - 03:12 AM

Thanks all - I don't think I was clear expressing my thoughts! I'm sure the glaze will survive as I've fired it higher before but I was wondering if the the glaze fit would be better if the clay was fired to maturity - alleviating the pinging and cracking of the glaze. OR will the glaze fit be poor irrespective of the firing temperature? Would a slow cool help at all?
Ann, I agree I've nothing to lose by trying - was just picking everyone's brain before putting them in with the next stoneware firing!

I am trying to develop a system to ensure I keep track of which clay is which - labelled my damp boxes and shelves but it's when pieces go into the bisque firing that I sometimes lose track - my white earthenware and stoneware clays look pretty similar when they come out and even the feel is much same! I mostly use the white earthenware, but had some stoneware pieces from a throwing workshop lying around. JUST in case anyone was wonder how on earth I could mix them up!!!

#111373 Using A Plastic Bin And Plaster To Reclaim Clay.... Anyone Do It?

Posted by Celia UK on 14 August 2016 - 02:06 PM

I recycle my slop and trimmings on a plaster slab - works just fine. Scrunch it all up, tip it out, ease in the edges so it doesn't run off, roughly level it out to an even depth and leave for a few hours (depends on air temperature). When it looks and feels about 'right' I roll it up and knead it and it's good to go!
The only disadvantage of using a slab in a plastic tub would be the time it takes to dry out the slab ready for the next batch (if you don't want to risk tipping the slab out to dry that is). That may not be an issue in a warmer climate than we have here!!!


#110833 I Like To Pack The Glaze Fire Tight

Posted by Celia UK on 01 August 2016 - 02:20 AM

Awesome Mark! As I've commented before, I think this is more than I've made in my four years of potting. If I could throw 10 matching 'anythings' in one day I'd think I'd been productive/clever!

As for combining a big show with a dive trip....well, I'm speechless. I'm quite sure it's great for your well-being to have a hobby that takes you away from your work, especially given your amazing work ethic. Clearly you are one of those people who thrive on it. Well done you!


#110831 Mixed My A First Batch Of Glaze

Posted by Celia UK on 01 August 2016 - 02:03 AM

Everyone needs to stop thinking about it so hard. The ideal specific gravity of any given glaze is dependant on your personal preference. It's something you record so you can repeat your results, or troubleshoot.
And unless you like headaches, stick to one system of measurements: Imperial or Metric. Combining them, or constant conversions between the two are a good way to mess with an otherwise good day in the studio.
If you weigh out 100g of glaze, just add about 50 or 60 ml of water (the measurement is close enough to the same number of grams at room temperature) and its usually enough to get it through the sieve. The glaze will likely be a bit thick for practical application, but you can then add water after that to make the consistency you want.

I must agree Diesel - on all counts above.

Back from holiday (cruise on the Rhine, Old Lady - BTW thanks for info on cups and sticks!!)) - I looked up my notes to find the formula and Pieter was right thinking the formula I remembered was Brogniart's. When I first came across It a few months ago, I saw that it came out pretty close to the guesstimate starting point I'd been doing anyway and wondered why there was such a complicated way of getting there.


#109484 Stilt Mark Question

Posted by Celia UK on 27 June 2016 - 11:19 AM

In my experience you still have to dremel off the 3 points from the tripod ceramic stilts. One potter I know, teaches  students to put 3 small dots of wax on the base, for the 3 stilt points to rest on. This stops the stilts fusing on to the base and you are left with 3 neat unglazed dots. Trickiest thing is to align the stilt on the dots and then place it all on the shelf without moving the stilt. Works if you can do it!

So you win some and you lose some Oly - at least you have a functional pot now!

#107781 Rubber Stamps

Posted by Celia UK on 30 May 2016 - 09:06 AM

It depends on how detailed the designs are. Some very detailed stamps, with little space between the lines will only give a very superficial image (2 on the left of the photo). Bolder, more 'open' designs work well (2 on the right).Attached File  image.jpg   63.92KB   1 downloads

Sorry...no idea what a k cup is and don't really recognise it in the photo! With the clue from Joseph, above - is it a coffee pod for a coffee maker?


#106281 Qotw: .... What Would Be A Logical Follow Up Question?

Posted by Celia UK on 04 May 2016 - 06:42 AM

Stuff everywhere at the moment - I say I'm multi-tasking but you could say I currently lack focus!
Testing letter stamps for my niece's wedding favours (130 different name tags to go on the heart-shaped dishes in the 2nd photo). Green ware waiting to go into the kiln. Bisqued pieces with tissue transfer decoration waiting to be glazed...
Plus 3 damp boxes of thrown bowls - 1 more to trim, then decisions re decorating all 9 bowls. This is quantity for me Mark!Attached File  image.jpg   105.57KB   1 downloadsAttached File  image.jpg   73.39KB   4 downloadsAttached File  image.jpg   43.94KB   4 downloads


#105530 Can You Be Cheaper Than This?

Posted by Celia UK on 22 April 2016 - 08:23 AM

Losing little bits of chamois ...I can empathise with that! Finding it in your reclaimed clay when throwing comes as a bit of a shock!!! Solution I got from a fellow potter, was to clamp one end under the lid of a small plastic film canister. The canister floats in your throwing water and the whole thing can hang on the edge of a tub or jug other whatever.Attached File  image.jpg   66.25KB   0 downloadsAttached File  image.jpg   57.29KB   0 downloads
