Thanks Babs,  I don't see that being a problem for this piece, (unless someone buys it for a pond/fish tank ornament). ;)

I guess I'll have to keep this one. Only noticed it after it was bisqued. -_-

#52231 Firing Schedule Madness

Posted by ayjay on 11 February 2014 - 05:20 PM

 

I like it too. What is it? what clay? What firing schedule

 

Thanks doc: It's just a small pot, the basic buff stoneware that we use at college, some torn newspaper strips applied as a resist while still on the wheel and then sodium silicate applied and dried with a heat gun and then ribbed out a little - bisque fired to ^05 then a wash of Iron Oxide, FF3110 and China clay applied to the cracks - (surplus sanded off the high spots) and a glaze of Jen's Juicy fruit with Liquorice on the rim - my glaze firing schedule is very simple - 100°C per hour to 1100°C and then @ 75°C per hour to 1200°C and a 20 minute soak - and then allowed to cool naturally.




#52189 Firing Schedule Madness

Posted by ayjay on 11 February 2014 - 06:04 AM

it seems like unique firing schedules are in fashion this season. Every time I find a new glazes I want to try it has a different firing schedule than anything else I've dealt with. Since I have a fairly large kiln, Skutt 1227, it is unlikely that I would want to fill it kiln with pots all having the same glaze. On the other hand I'm not really excited about firing it was just a few pots in it.

 

Is anyone else frustrated by this?

Have you found a way of coping with this besides avoiding glazes that have unique firing schedules?

I know exactly what you mean: I don't have the amount of production which allows extensive testing on a sensible time scale, so I do use published glaze recipes and sometimes change them a little to suit my purposes (sometimes I even convince myself I know what I'm doing).

 

 I just remain grateful for those published recipes which someone has probably worked hard on and decided to share with the wider community, they don't have to share, any many don't, if they don't fit my simple firing schedule I usually try them as is the first time and if they don't work for me they get tweaked once or twice and then abandoned if they still don't work - there's plenty of good glazes that do - how many do you really need?

 

I'm reaching the stage where I want to have a half dozen glazes that I know will work, can interact positively with each other and maybe test a new glaze with each firing, hoping for one of those spectacular results, (I've managed acceptable so far, still waiting for spectacular).

 

Here's my most recent favourite, not spectacular by any means, but I rather like it (and I need to sort out the lighting for pottery pics).

#51953 Kitchen Compost Jar

Posted by ayjay on 08 February 2014 - 05:28 AM

I made one, it's in daily use, no fancy gaskets just a well fitting lid, it's deliberately small enough that it needs emptying daily into a larger plastic dustbin just outside the kitchen door which gets transferred to the compost bins weekly.

 

If it helps to know the scale: the black tiles are 4"X2" and the white tiles are 3" high - don't know why I didn't just measure the pot. :rolleyes: :lol:

My wife's awful pots. :ph34r:

 

(Harsh, but fair!  -  I just knew it couldn't be that hard).

 

Please don't hate me. :D

 

 

 

 




#51562 Brushing On Glaze?

Posted by ayjay on 02 February 2014 - 08:37 AM

I often brush my own stoneware glazes on (although spraying is beginning to take over), I make a solution of CMC (5mg to 1 pint of water)and add enough of that to thicken the glaze.

 

It won't need much, 20ml of the CMC solution to 100ml of glaze would almost certainly be too much:  it's going to depend on how wet they are to start with, but if I'm mixing small quantities of glaze I normally use 90 -100 ml of water to 100g of the dry glaze.

 

Then brush on three coats, the CMC stops the water from being instantly sucked out, but do remember you're not house painting, you're applying glaze with a brush, a soft fan brush is best.

 

(I would fret however, if my tests were applied in a different way to how I intend to make the finished product).

 

 




#51345 Help On Ingredient Substitution Needed!

Posted by ayjay on 30 January 2014 - 07:11 AM

For a glossy clear ^6 I use:-

 

20 Potash Feldspar

20 Standard Borax Frit

15 Wollastonite

20 China Clay

6  Talc

19 Silica

 

for a creamy white add 4 Tin oxide

 

If you have those ingredients, this works well for me on  Earthstone ES5 and the  Standard Buff stoneware at college. .

 

There must surely be even simpler recipes for a clear glaze.

 




#49611 Mastering Cone 6 Glazes - Priced Way Out

Posted by ayjay on 07 January 2014 - 12:14 PM

I've put in a request to my county library, but looks like we don't have one. 

We don't have a copy in the Hampshire Library Service either, but they got me one from Sunderland Uni.

 

I think it cost me £2.00 or £2.50 to borrow from out of county.




#49176 Basic Glaze Recipe To Work/experiment (Newbie Question)

Posted by ayjay on 02 January 2014 - 01:31 PM


 

I am not certain in the UK we can get all the frits. My supplier lists only Ferro Frit 3110, High Alkaline Frit, Calcium Borate Frit, Lead Bisilicate Frit, Lead Sesquisicilate Frit and Standard Borax Frit.

 

Scarva keep all of the commonly used American frits and can supply by mail order.

 

Finding an easily available UK substitute will almost certainly work out cheaper and more convenient.




#47665 What Would You Like Santa To Bring?

A 10X20' addition to the studio would be nice,

A 10 X 20 studio would be nice!

 

I'm currently using my garage which is roughly that size, but I share it with 5 bikes, a  large chest freezer, an 8' X 3'  carpenters bench (and many ancillaries and associated materials), and a load of fishing gear.

 

There's some clay in there somewhere too, plus two kilns and and a wheel.

 

A cure for my wife's MS would be better.

Thank you, - hmm, instinctive pottering.  B)




#43827 Creating Patterns On Pottery

Posted by ayjay on 08 October 2013 - 04:54 AM

I'm assuming you use the red food coloring for sketching when on leatherhard clay.  What about on bisque pots?

I use a straightforward HB pencil to mark out on bisque  (and usually wish i hadn't  - my artistic skills leave a lot to be desired) but the pencil works fine.

Thanks for replies, will try and get hold of mender friend,

 

Tried filling with glaze with no luck on a piece a while back,

Bath Potters (in the UK) do one for stoneware and porcelain if you're firing that high, (and more often than not they'll be cheaper than Potterycrafts).   I have no idea of its efficacy.
