Underglazes, Dipping Glazes, Rabbit Rabbit Rabbit Rabbit

Morning all,

Apologies for things going quiet on the blog – 2018 has thus far been a challenging year. Which gives me all the more reason to enjoy and celebrate clay when I get the chance.

A few weeks back SB’s studio opened up again on Tuesday nights and I popped down. I made two little dishes for mothers day for my mum and mum-in-law and a couple of bowls. My intention was to start playing with underglazes and try to understand dipping/spraying glazes more rather than just brush on.

The underglazes were ok to use, but to be vibrant they were low fired and so not suitable for food SB said. But as the dishes were more like little trinket dishes this was fine. The underglazes were fine, one colour must have been a little thick or not happy as it bubbled and burst away, but I had more issues with the clear glaze I had to brush ontop that got a bit claggy (is that a word?). I think SB has a clear crackle I can use next time that was more light and less err.. claggy.

The green glaze I sprayed on gave a lovely coverage but a blue cobalt I used came out much more strongly that I had anticipated – a bit garish. And the tags yard I used under the spray on glaze burnt away mostly, so was barely visible at all. Overall I really didn’t like either of the green bowls I made at all. Last night I worked to re-glaze them and see if they could be salvaged. I don’t like discarding things – I don’t like to be wasteful. So I’m hoping they look a little better with a second firing..

I also poured on a blue dipping glaze. I think I need to get much better with my pouring or perhaps some glazes are more forgiving than others – because the coverage was really uneven, especially on the sides of the dishes. Likewise I used a blue cobalt and tags yard to try and bring out some detail in the bowl, but again the blue as garish and the tags yard virtually burnt away. Hopefully next in two weeks or so I’ll be able to get them back in a better condition. Regardless I will post the results as its useful to share failures as well as successes!!

And so apart from battling with glazes, I decided to make a rabbit last night! Well, a hare. I had seen an article in Clay Craft where they used two small pinch pots to make a basic rabbit shape. I have wanted to make Little One a rabbit for the garden since I began working with pottery again – but I was intimidated by sculpture. Handbuilding is such a different skill to throwing, and I have never had much luck with coiling and pinch pots. But my mind was restless with other things and I just started, regardless. I think seeing the Clay Craft article gave me confidence. I joined two large pinch pots and used a third smaller pinch pot for the head. And from there I pushed, added, scrapped, moulded and prodded the clay into a hare standing on its back legs. I worked a little from an image of a real hare on my phone, but as you can imagine the phone kept shutting down, so it was largely from eye and memory. I wasn’t going either for ‘animated’ nor ‘real life’ but something in between I guess. I battled with memory vs a picture, as a hare has quite long front legs, which looked strange to me when I made them in clay, but the proportions were roughly correct from the photo of the hare.

The plan is to use oxides and underglazes to glaze him but keep it quite low key. I’ll definitely be doing a few test tiles before jumping in and glazing him – that much those awful bowls have taught me!!

I’d like to have a go making more animals – mostly for the garden and for my Little One to enjoy. It was a really different building experience to throwing or slab, and I’m glad I finally made a rabbit (hare), just in time for spring! As ever, I’ll do my best to keep you posted

Cast Munchkin Pumpkins!

Yes, Halloween is long gone. But since writing a post about making plaster casts, I have been busy making as many munchkin pumpkins as I can! And I love the results! As you can see I’m channelling my inner Kate Malone.

Unless specified otherwise these pumpkins were glazed using Botz glazes. As you’ll see below some are wild pinks, blues and metallic! Whereas others are more natural looking with greens, browns and white.

Some of these pumpkins have already been picked up by family but I will make sure I get a few on etsy asap!

Happy Christmas everyone!

Love

Second glazing

Following on from my single firing post – where the glazed greenware came out in one piece, but the glaze hadn’t been quite as dynamic as I had hoped… I re-glazed everything and fired again!

In order for the glaze to take well I heated the mugs/bowls etc using a hair dryer and added thin layers of extra glaze, two extra coats in total. I also added an extra stripe of green or blue as the best interaction was between the indigo float and seaweed.

I don’t think the toasted sage Amaco Potters Choice glaze is a great one for encouraging movement and interaction between the two glazes, in the same way the tenmoku glaze is, but nonetheless I am much happier with the results so I thought I’d share a couple of before and after photos!

Here is an example of the mug, with an added stripe of blue:

And this is the bowl!

I like the green seaweed and the indigo float, but I want to find a better base for the two of them. The range seems to focus on darker under coats, which wasn’t what I was after. The only other lighter colour seems to be oatmeal which is quite yellow-y from the picture.

Actually the toasted sage comes out quite grey as the photos show, which in of itself is a lovely tone but wasn’t as light as I’d hoped it to be. But at least now I know I have a nice grey glaze – so every cloud has a silver (toasted sage!) lining!

A couple more things using this glaze combination and tenmoku in my etsy shop – check it out!

Birdbath

A dear colleague at work is leaving and I wanted to say thank you in a meaningful way. So. What better than making him something! I know he loves his garden and so a flower pot or birdbath came to mind. Having made a few oblong slab built flowers pots recently, I thought a birdbath might be fun to make. 

I began with a former shape. I used a straw to poke through three holes, however I wasn’t sure what detail or design to do. I wanted I didn’t know if a country garden, traditional birdbath might be most appropriate or something a little more fun. I thought perhaps a little bird on the side but it didn’t seem very original. Something work related would be fun, perhaps? So I created a little tube train coming out of a tunnel along one side!

In my haste to glaze and fire it before he left, I read that you can use Mayco glaze on leather hard clay, meaning a single firing!

…well. Needless to say, I thought the piece was dry and after opening the kiln, my heart sank. It had cracked and broken into pieces. 

Not to be put off, I got straight back to my bag of clay and this time I rolled a slab and used a large mixing bowl to form the base. I cut a separate piece for the rim and once these were suitably dry I made the holes and stuck them together. I let the pieces dry a little more before using  my Mayco glazes and designer liners. I let the pieces dry over the weekend while we were off visiting Middleport Pottery (blog post to follow!) and I fired the pieces Sunday afternoon. 

I was so happy and relieved!! The colours came out well and most importantly it was all in one piece! I ran to a hardware store and rather than paying for expensive chain I found three sink-plug chains. These chains were perfect, 45cm long, rust resistant and they even had the little opening loops at each end!

I gave my colleague the birdbath this week and he was absolutely chuffed. It feels so good to show someone your thanks and gratitude with something you’ve invested time and effort in. I’m going to miss him at work but at least he has a little birdbath to remember us all by!

Birdbath making was fun and the actual shape is no more complicated than a dish. I’m looking forward to making the next one! I’m also really happy I can now single fire my pieces using the Mayco glaze – saves time and electricity!!!

Look out for some birdbaths on my etsy page coming soon!

Blue – Brown! Amaco Potters Choice

A post a few months ago, Recent Work, showed a piece I had constructed in a relatively short amount of time but it has been a long time waiting to glaze. This is because I’ve found that sometimes my glaze choices have let me down! For example I love the depth of many of the Botz glazes but they’re thick and you need 2-3 coats, which means it just isn’t suitable for a finely textured piece. I’ve recently been using SB’s Amaco Potters Choice glazes which I really love! However she mostly has blues and pinks, and sometimes they merge into an almost denim colour. Which, if the desired effect is great! 

One glaze combination I’ve been enjoying is the Potters Choice combination of brown (55) and blue (pc20). Usually the blue is a Base colour you layer on top of however I’ve been putting the brown on first and using the blue to accent and it’s worked surprisingly well! 

I first used this glaze combination on a re-glazing and I liked the result. I used a dish made of scraps at the end of a studio session set in a former to try the glaze out on bisque and the depth of the brown was beautiful, particularly where it accentuated the marks underneath.

Re-glazed little vase.

I then tried the glaze in earnest on a larger piece I’ve been working on. It was built of textured strips, inspired by how urban forms and high rises begin to decay and look dated, are abandoned and sometimes find new life either through rehabitation or being reclaimed by nature. I used the blue glaze to highlight areas and wax resist to create contrast against the brown. I’m really happy with how it came out, the textures and marks are really visible. This is definitely a combination I will work with again! I want to put this piece in the garden near a crawler to let it become encapsulated by the plant. Hopefully it’ll grow in and out of the different parts and the green of the leaves will contrast with the deep brown.

Botz Glaze Review

Bots glazes! Thick brush on glaze that can give a punchy colour, but that can also be sensitive and shift around or not come out as expected. Botz were the first glazes I used because these were the glazes SB had in her studio and they are affordable at around £5-13 depending on the supplier and size of pot.

I began by buying ‘Black Blue Speckle’ and ‘Ice Crystal’. However I used them on two pieces that had quite a lot of detail and these were ultimately swamped I felt and the overall effect did not bring out the detail in a way I had hoped. The Black Blue colour had been as expected but the Ice Crystal had given a more sandy, beige effect rather than the white/blue speckle I had been hoping for. These items were made at home and fired at SB’s studio.

When I fired the Ice Crystal at home however, it gave a dramatically different effect! This is exactly the same glaze as the top white pot, but fired by myself to cone 9 (1260 oC).

wp-image-216214756jpg.jpg

I used the Black Blue again on a coffee jar with a white from SB’s studio and this was much more successful I felt.

wp-1477167244320.jpg

With my confidence restored a little, I decided to buy a couple more Botz glazes from Bath Potters as they were offering 10% off for first time customers. So, I decided to buy a Basalt Grey and a satin matt white called Creme. I didn’t have time to do testers and so used the glazes on some thrown pieces I did recently, and a couple of left over stars from Christmas to be used as testers.

wp-1486816383048.jpg

Overall I was reasonably happy with out the pieces came out, however the Basalt Grey was really more brown. I was surprised as I painted it on quite thickly for two coats. I didn’t think I would be able to get a third coat on without it pulling away, however perhaps that’s just what it needed to reach that deep stoney grey colour.

wp-image-918864812jpg.jpg wp-1486816466969.jpg wp-1486816449308.jpg wp-1486816432715.jpg wp-image-2107783389jpg.jpg wp-1486816397820.jpg

Overall I find the Botz glazes to give good coverage and depth of colour (holding judgement on Basalt Grey), however they are far less predictable than say the Mayco and you use up much more glaze per coat than the thinner applying Mayco. For example air bubbles appeared in the white and in one area it completely shifted away from the ceramic underneath – there must have been grease or something on the clay, as I’ve no idea why this would have happened. The white also showed brush strokes in some areas, which I found with the Ice Crystal and grey as well, wheres this was not the case with the Black Blue. I had hoped the colours would interact between the gray/blue and white more, but this didn’t really happen.

Overall I like Botz glazes, however I think to get the desired effect I need to spend more time with testers and experimenting with firing at different temperatures. I would definitely buy them again but they are less versatile in terms of mixing and layering. (Perhaps they aren’t, if you have a different experience please let me know!). They also obscure surface texture quite a lot due to the thick layering required, but the colours can be striking and have a depth and quality to them that I really love.

Mayco Glaze Review

I said a few months ago I would review the glazes I bought before Christmas and despite having used them and put a few posts up, I haven’t given my opinion on how they work, their colour, their versatility, or overall effect.

So this is what I am hoping to get across now! Of course these are just my opinions and I hope I have explained them properly but please feel free to comment and agree or disagree! And obviously with all ceramics, so much with the glaze depends on the application, layering and how long they are fired to and what temperature. I will explain these as I go along, in order to give you the clearest idea of my making process!

So. Where to begin. Well, before Christmas I was looking to build up a glaze collection (formerly only owning two Botz glazes – review here) with glazes that were versatile and reliable. I took to Twitter and Mayco glazes were recommended as reliable, even in coverage, less-drippy and forgiving for want of a better word.

I decided to go for the Mayco Foundations glazes, Sheer. I hoped with these glazes I would be able to intermix the colours and any stamp/texture decoration would come through. My experience from the Botz glazes, which are heavier, thicker glazes, was that the decoration was often lost. I bought 5 tubs:

  1. Milk Glass White
  2. Clearly Jade
  3. Blue Diamond
  4. Sooty Grey
  5. Crystal Coral

I also bought three ‘Designer Liners’, white, red and green.

wp-1479424262105.jpg

In one of my first firings at home I did some colour testers and following the recommendations on the bottles, did a gradient of 1-3 layers. All the colours were a little less bold than expected despite the recommended 3 layers, but overall I was happy with them apart from the Crystal Coral. The first picture here shows the Blue Diamond tester with 1-3 layers of glaze and the one below in my hand shows 4 colours (except Milk Glass White) in 4 layer stripes. The second image shows Crystal Coral on my tester and the third square image shows how Crystal Coral looks online. As you can see, it is much more pink and vibrant. In reality, the Crystal Coral even with 4 layers, was no where near this colour. In hindsight if I had wanted a more vibrant pink, perhaps I should have gone for Floral Pink. In these instances the glazes were fired to cone 04 so perhaps 06 would have made a difference, I don’t know.

Despite being a little more ‘sheer’ than I anticipated and the coral colour being more clear/white than pink, the glazes behaved really well in the kiln! They were easy to apply, they give a thin layer which can be built up to the desired thickness which as I have said, can significantly change the depth and boldness of the colour. They are a really steady glaze to work with and were great for my Christmas decorations!

wp-1482080688772.jpg

I also used the designer liners one a few items. These are clay based glazes (or does that make them slips?) that you can use to add fine detail to something. I found that without adding a clear glaze on top (for which I just used a single layer of Milk Bottle White) they flattened and were matt against an otherwise shiny background. The flow of the green was much better than the white for some reason, but the green smudged with a thin layer of white on top – or perhaps the white did too but it wasn’t visible. Regardless you certainly need a steady hand as they don’t budge an inch! I found the green to be more successful than the white overall. The white looked a little like Tippex in my opinion… But they are definitely useful for accentuating detail.

wp-1486816335743.jpg  wp-image-850206167jpg.jpg wp-1486816347743.jpg

Finally I tried to use the glaze for the bubble effect, (inside the grey cup with the green detail). I knew it was a long shot and I was right – it didn’t really have the desired effect, but it is certainly a technique I’ll try again in the future.

Overall these glazes, for the most part, do what they say on the tin. They don’t shift or move when firing, they can be layered, are easy to apply and accentuate detail nicely. They are very much a safe option and a little goes a long way. For me, I was hoping they would be a little bolder and the colours as strong as their depictions online, but then that’s always the trouble with buying something you haven’t seen or used before online!

In terms of value for money, I bought 1 pint (472ml) pots for roughly £15 including VAT from PotClays which was pretty much a standard price across the different sites. PotClays are expensive for delivery however, starting at just under £10 (whereas Scarva for example, adjust to the weight of the item and can be as little as £2) which is a shame. The PotClays people are really lovely to deal with and quick to communicate. If their postage was cheaper I would buy more from them as their website and range is pretty great compared to other sites, but I know they are also a family business and need support and so I try to buy from them when I seem them at events.

Overall, I’d definitely buy Mayco again, but I’d explore their other glaze options before buying more of the Foundations Sheer range.
