#78096 I'll Never Be A Real Potter.

Posted by High Bridge Pottery on Yesterday, 01:09 PM

I just hope that those of us who are not "REAL" potters, are also NOT "VIRTUAL" potters!  I'm not a gambler, but I bet there is a game for virtual potters somewhere in the web galaxy !


On the other hand..... virtual pottery would be clean, neat, tidy, not dusty, wouldn't make my hands itch, swallow cash, ....... or be as much FUN!


Totally an App for that :D https://itunes.apple...d380090605?mt=8

#78023 Guess The Rock.

Posted by High Bridge Pottery on 25 March 2015 - 05:06 PM

I love that I can read the rock "erupted during a phase of cataclysmic volcanism 450 million years ago." and now try and melt it onto my pots :D


It's not just a glaze, its a 450 million year old glaze. Forged in the cataclysmic volcanic eruptions of the Lake District.

#78017 Guess The Rock.

:D Thank you for the pdf.


I was in the middle of the Lakes up the Langdale Pikes, they are actually in the picture above. I walked up the part that looks like her face :D That was where I found these.  The Langdales is Borrowdale Volcanic Group. It says "The BVG lavas are mainly ANDESITES, with some BASALTS and RHYOLITES."



Some of the samples are a darker rock but most being made up of some sort of crystalline rock.

#77280 Can I Swap Neph Sy In This Glaze?

I use CTM and their soda feldspar gave me nice burnt edges. Will find the glaze recipe.

#77243 What Do You Get Out Of This Forum Interaction?

Posted by High Bridge Pottery on 12 March 2015 - 08:20 PM

I really like the multitude of answers you can get here as we all know most of the time "it depends".


I also love those little gems you find in unexpected places. You never know where a topic might end up.

#76853 Help With Ordering Newbie

Posted by High Bridge Pottery on 05 March 2015 - 02:55 PM

Don't know if you found the key underneath for the test tiles. What you are seeing is the wash being painted on and different glazes producing different colour variations. (Note to self, read other posts first  :rolleyes:) Just saw the other post xD


To get all the different looks they have on those tiles you need the wash and 4 different glazes. Some of them are fired to cone 4 and some to cone 6.

If you are looking to get the most variation out of the smallest purchase I would maybe buy a clear glaze, white glaze, a semi-matt or whatever kind of matt you are into. Get a few mason stains that you can colour the glaze/clay/paint and maybe a wash or two for painting under or over glaze.


That would probably get you started. It all depends what kind of surface you are looking for and the colours.

#76590 Cobalt Wash

Posted by High Bridge Pottery on 02 March 2015 - 12:28 PM

I have this recipe for a blue wash, never tried it but I have had success mixing my clay with 0-10% cobalt to make a coloured slip, don't know if that is classed as a wash.

Red clay 100g
Cobalt oxide 4g
Manganese Dioxide 4g
Water ~
Enough water to make it into a watercolor consistency. The iron in the red clay and the manganese soften the harsh blue that you can sometimes get using the Cobalt alone.

Also this one, I am sure you could try without the manganese dioxide.
Grey Blue
Cobalt Carbonate 60
Manganese Dioxide 20
Gerstly Borate 20


Underneath are my tests with Cobalt Carbonate 1%, 2%, 4%, 8%, 16% and 24% with the clay body. It is under a white glaze.

#76483 Heat Proof Surfaces

Posted by High Bridge Pottery on 01 March 2015 - 01:00 AM

A few bricks or a paving slab? Some people have mentioned using cement board. Have a look at this thread for more info http://community.cer...alls#entry56835


if it is the kiln you have posted about it looks like it has a big air space between the kiln so I bet you could probably put it on any table. Still if you want to be extra safe put it on something like a paving slab or cement board.


You shouldn't take stuff out of the kiln before it is under 100 degC so that surface shouldn't matter. I just take mine out and put them on a wooden bench, nowhere near hot enough to singe/burn the wood.

#76271 What Causes Glaze/clay 'tide Mark'?

Posted by High Bridge Pottery on 27 February 2015 - 05:42 AM

I'm pretty sure it is to do with sodium

#76127 Finding Your Own Style...easy To Say

Posted by High Bridge Pottery on 25 February 2015 - 04:58 AM

It is funny how many things I have thought 'this is my style' till I watched an old pottery video again and saw that I was obviously inspired without knowing it and have just copied what I have seen. I always see my style as a mix of sensory inputs run through my brain circuits.  

#75936 Standard Ceramic Glaze Issue

Posted by High Bridge Pottery on 22 February 2015 - 12:53 PM

Sodium silicate should have thinned down the glaze really, sounds like there is an ingredient in the glaze that is causing mischief. Is it a commercial glaze you have used before?


I remember reading stuff about glaze cracking/gelling and why but I can't remember it any more. I will see if I can find it again.

I haven't managed anything yet for this challenge :( but my first ceramics monthly mag arrived with a great front cover that gave me some inspiration. Work by Julia Galloway, she must have seen the challenge :}

#74867 Very Pale Cream Glaze Tests

Posted by High Bridge Pottery on 05 February 2015 - 08:15 AM

You could try a different feldspar, I find cornish stone gives a much creamier glass. Maybe swap out 50% of the soda for that.
Increasing the china clay could also get closer to the off white but it will become more refractory.. Maybe a darker ball clay could work too. Not sure about the colourants, a very low percentage could give you what you want.
Here are some of my melt tests, if you look at the feldspars across the top it goes soda, potash, cornish stone. Cornish stone to me looks the most off white.

Do you have any photos of your tests?

I like the idea of making a lampshade that looks like the sky in the day and when it gets dark stars would shine through the clay. Not sure how that would be executed other than a load of small holes  :huh:
