Single firing

First of all, to clear up an issue from the previous post. I soaked my flaky kiln shelf and used a steel wire scrubber to remove the flaky batt wash and it worked like a dream! I thinned my batt wash with water to the consistency of skimmed milk and reapplied a thin layer and left it to dry. My kiln shelves look as good as new!

And now to single firing. I had used this technique when I made a birdbath as I was tight on time. The Mayco glazes are pretty steady with no movement at all. They also give a pretty good colour and coverage with just two thin coats. I glazed greenware and single fired the birdbath and it came out great. However I didn’t know how this technique would work with Amaco glazes.

I did a lot of throwing last weekend knowing that I wanted to use my Amaco glazes. However when I looked at my pyrometric bars, I saw I only had one or two bisque temp bars left! My little Olympic Kiln is old skool with a manual ramp dial and kiln sitter. So with precious bisque bars in short supply I thought about single firing my thrown mugs and bowls.

Amaco Potter’s Choice glazes mix and move and create beautiful effects but in order to do so, you need to apply 2, 3 even 4 coats depending on the thickness. I let my pieces dry to leather-hard and applied two coats of Toasted Sage then two coats of Indigo Float and two of Seaweed on alternate pieces. With all the glaze on they took a long time to dry but I was patient. I didn’t want to add too much because I didn’t want them running and ruining my lovely new clean kiln shelves.

I managed to pack the kiln with 3 layers and get everything in! And as I was doing a single firing I did a really slow low heat before raising the temp after an hour or two.

I fired to cone 5 and it took longer than expected to get to temperature, but it did get there in the end! I left the kiln to cool and opened up the lid holding my breath..

..Everything was in one piece! fantastic. But the glaze? ..it looked dull and thin. Not like Amaco at all and obviously not the effect I was hoping for!

The only ones that looked decent were the two pots I used the tenmoku on first. I was hoping the Toasted Sage would be a little lighter than the grey but then again I hadn’t done a test tile and trying to guess colours from the Internet isn’t a good idea.

I admit I was a little disappointed but it’s all part of the learning process! I think overall I was happy that my single firing worked, it was just a lack of experience with Amaco glazes that meant I didn’t add enough layers.

I am confident that should I want to single fire again I could achieve results close to what I wanted.

I spent this morning re-glazing my mugs and bowls for a second firing! At least it won’t need such a long slow ramp as the mugs ceramic now but I still don’t want to rush and risk an exploding kiln! I added more layers of each glaze but also more stripes of Indigo Float and Seaweed. The colours look great when they interact so hopefully this will achieve that effect.

20170805_145347 Once they’re dry I will fire them again, sometime early this week if not tomorrow and post the final results!

I guess I’m must also admit that I’m keen to get single firing experience as it saves a lot on the electricity bill!! And if it produces the effect you want, then why not single fire? My only advice is to make sure your pieces are dry as a bone before firing and then allowing a long slow ramp. I was advised to leave extra clay clean from glaze to allow gas to escape from ghee clay body, but I just left the bottoms clean as usual and this was fine.

Happy potting!

Throwing and Kiln shelf issues!

During the week I very nearly signed up to an intensive throwing class… it was far away and expensive. But I really want to improve my throwing. However money is tight at the moment and so rather than spend the time and money going somewhere else, I thought I should try and have a good few sessions at home! I was hoping that the sun would be out and I’d be able to save the mess in the house by throwing outside… but no. It’s rained on and off all weekend.

Nonetheless! I got my little table top Shimpo out of the toilet in the garden and cut out about 8-10 chunks of 500g clay, and two 750 chunks. I wanted to throw some mugs and a couple of bowls.

Throwing, unlike previous times, went well! I’ve really tried to put into practice what I have been told and seen online on youtube and Instagram. Gus the Pothead is one of my favourites on Instagram, I’d definitely recommend checking out his throwing videos!

I managed to make eight mugs about the same shape and size. I wired them off and then let them dry a little on the bat. I think I might be going wrong here – should I be taking them off the bat straight away? Two got damaged when I was trying to take them off so I let them dry a little. Any advice on taking things off the bat would be appreciated! What works for you?

I threw two more mugs and then my bowls suffered a similar fate as the two mugs – they completely collapsed as I was trying to take them off the bat. It was so frustrating! I finally managed to throw another large bowl and keep it. But I did as I described earlier, I wired it off and let it dry out a little before moving it off the bat.

My plan is to glaze at greenware stage with Amaco Potters Choice and do a single firing. However herein lies my next issue. My kiln shelves are flaking! The bat wash flakes off and falls onto a pot. How do I stop this happening? Does bat wash come off with water or do I need to do something else to remove it all? I read perhaps a very thin coat is better than a thick one… Please! I don’t want to ruin the cups and bowl I’ve thrown this weekend. And as SB’s studio is closed I don’t have another kiln to use!

Love in advance

2017 is here to stay

Well. Politics, both domestic and global, seems intent on repeating mistakes that were sworn to never be repeated. It’s been a tumultuous start to the year and one that many would like to forget, but as it is, 2017 is here to stay.

On an individual scale, life has been busy. There doesn’t seem to be enough time in the day or days in the week. Since the holidays and heading back to work, it’s been difficult to find time to do anything other than get on top cleaning/sorting/tidying the house however finally this weekend I got a few hours to myself and I thought – let’s see how a little bit of throwing goes!

img_20170129_155955_167.jpg

And actually, despite perhaps two-three months without throwing, it actually went reasonably well! I decided to try and batch throw a few mug shapes. Four mugs were produced, a bowl and a jug.

However, the jug and bowl were sacrificed in the turning stages – I need to practice turning as much as throwing!

 

I decided on pulling a few handles as well and again, this didn’t go as badly as I imagined. After being left to dry for a little while, four were selected and added to the mugs. Again I need to work on making my handles a little longer and thinner – they’re quite chunky at the top and this looks unbalanced when attached to the mug.

I carried on throwing this evening – the wheel was out, so why not! It’ll be at least a few days if not weeks before I use it again, so why not make the most of it? I played around with some recycled clay and indenting a thrown shape. It’s a little basic, but I quite liked the rippled rim and little narrow spout of these two, so I decided to keep them.

I even managed to convince Beloved to have a go this evening! Spreading the ceramics love throughout the household! I’ll have Little One making little cups and bowls in no time!! In fact, that’s a great idea.

After all the making before Christmas and the slurry from wp-image-455328090jpg.jpgthe wheel, my scraps tub was full and so the process of reclaiming began. That’s truly something I love about clay, there is so little waste.

I’m hoping that in the next few weeks I can make enough to do a biscuit firing and then two more glaze firings – one with the Mayco Foundation glazes, a low temp, and one using the Botz glazes, high temp. Although there’s no point just throwing anything in, it’d be nice if the kiln was full of things I wanted to make and give. In which case, it might be a while before the firings happen – but that’s ok. Good things come to those who wait!

Also, the second series of the Great Pottery Thrown Down starts this week! The contestants look a bit ‘cherry picked’ and seem to be far more experienced than amateurs.. but I’m looking forward to it all the same! For inspiration if nothing else.

PS over and out! Take care of each other xx

Merry Mayco Christmas!

Ho Ho Ho! Meeeeeeerry Christmas!

I spent a good few hours last week making Christmas decorations and mugs in preparation for my first biscuit firing at home – and I’m happy to say it worked great! The kiln fired perfectly at home and the results were fab.

With a loads of Christmas tree decorations, trinket boxes and mugs to glaze, I got going with my new Mayco foundation glazes. It recommended 2-3 coats, so I applied 3 on pretty much everything. I also did a few testers indicating 1, 2 and 3 coats. The blue, grey, green and white came out well with 3 coats, although I’d go as far as to say go for 4 coats if you wanted a more bold colour. The ‘coral’ pink colour was quite washed out at 3 coats, so I’d definitely do 4 coats or even more if possible to try and get a bolder colour.

Having biscuit fired one day I was able to get the items glazed and fully dry by the weekend and fire for glazing! This was really exciting as I’d pack the kiln to the absolute brim, balancing stars on kiln accessories just to try and squeeze everything into the one firing. I even use the bottom of the kiln and tripods to add an extra layer. I don’t know if you should use the bottom of a kiln, but I did and it worked out fine. This isa  photo of the kiln lid being opened after my first low temp glaze firing!

And here are a few more pictures of what came out. You can see I used a designer liner to highlight some of the snow flake pattern and on one of the stars I used a blue glaze over a white glaze, which gave a nice effect for the snowflake.

And here they are hanging in the tree! Lots of friends and family will be getting these little stars for Christmas!

And then mid-week I was able to get back to SB’s to pick up some things that had been glazed a few weeks ago! She’s shut for Christmas now, but I was happy to pick up a few items as they were made as presents for people as well.

First is a little cup I threw on the wheel and added a pulled handle. I twisted it slightly and then glazed on an angle too – I really love this little mug, although if the twist had gone the other way, it would be comfier to hold. But it isn’t bad! And the new glazes SB has got are great – the colours are vibrant and overlap really well!

These were a pair of mugs I made, using lace to add detail to the clay and then highlighting the lace area with the pink/purple glaze and the rest of the mug with the blue/brown and a white glaze inside. I really like them and I know they’ve gone to a great home!

wp-image-1263278580jpg.jpg

And finally a tea jar to go with my coffee jar and two little vases I made! The tea jar came out great, although the lid slightly curled up.

wp-1482080841897.jpg

And the two vases were inspired by my Phnom Penh vase – I used the techniques from the larger vase to develop these little pieces – there is a 3rd but it needs more work so these were glazed in anticipation first!!

wp-image-677523518jpg.jpg

It was my birthday recently and beloved got me a spot on a glaze making class in the spring, which is so exciting! Didn’t he do well? And I got a few ceramics books and bits and pieces from friends and family. I’m one lucky Potter Girl.

So there we are! Christmas eve is a week away and I can’t wait for some time off work to spend with loved ones! Clay is all wrapped up for now but no doubt I’ll be back on it again over the Christmas holidays – much remains to be made.

Wishing everyone a fantastic festive period and a happy and healthy 2017! Take care of yourselves

A few pieces, fresh from the kiln!

Hello!

I wanted to share a few photos with you of finished pieces. Often my posts are talking about the construction/formation process or ideas, but it isn’t so often I get to post about finished pieces. I won’t be going to SB’s studio for two weeks or so, so this morning I popped over to collect a few items I had recently glazed and that she had fired.

These pieces are more experimentations with shape, form and glaze. I slowly feel like I am getting the hang of the construction process but I am still getting to grips with glazing! Whereas I know roughly what colour items might be, it’s still difficult to decide upon what glazes or colours for different items.

Of the pieces that came back to me this week, I really like the consistency of the white glaze used on the bowls, egg cups and inside the star mugs and bowl. The tek moku glaze on the turquoise/light grey bowls created a really interesting effect too, although I think it might have had even more impact with a different coloured glaze.

 

The star mugs were actually glazed with a low temp blue and a high temp white and fired at high temp. I was really happy to see how clearly the stars came out and the even coverage of the blue glaze. I think the contrast between the blue and white is classic and effective, I particularly like the white on the inside I think it gives a more professional finish.

Finally the white outside and turquoise/green inside bowls look great! Both glazes gave good coverage and the combination of colours is one I will definitely use again. It was interesting to see the different results depending on the shape of the rim (thin and pointed or thicker and rounded) and whether the green was taken right to the edge or the white brought in.

Each time some pieces come back, I learn a few lessons and I feel that my next glaze decisions and techniques are better informed. Happy!
