FAQ

Yes, unless it says otherwise on the description of the particular item all Derek Harbinson Ceramics products can be run through the dishwasher as often as you like. If you don't have a dishwasher you can try getting a teenager to wash up, but good luck with that.

The nature of producing small batch pottery is that I don't hold a lot of stock at one time. At the studio I make until there are enough items to hold a sale. Shop opening times and dates are all advertised in advance on Instagram, the blog on the site here and via the email. Items tend to sell out quickly so follow me to be notified or sign up to the email.

Yes. Clay is fired in a kiln at up to about 1260 degrees C. So in your domestic oven that goes up to 260 at full whack ceramic casseroles and dishes are barely noticing that it's got a little warm. Although I wouldn't recommend using a decorative vase of bowl as cookware.

Good question. Handmade studio pottery goes through various time-consuming, labour intensive processes before it's ready to go to a new home. Clay is first thrown on the wheel. Then it has to dry out enough to be trimmed (this can take a few hours in summer and days in winter...). After that, when it is completely dried out (this can take days or weeks, depending on temperature in the studio, size of the piece, time of year etc) it is 'bisque' fired - this turns clay hard and brittle. Only then can the piece be glazed and fired again, making it much more robust, waterproof and useable. Add to that that the kiln is only fired when it's full to save energy and you can see that a simple mug can take quite a while. Luckily though, it will then last more or less forever, as long as you don't drop it. Ceramics are among the oldest man made objects around, so waiting a few weeks to make something doesn't seem so bad.

All the glazes are mixed in the studio from raw materials. Glazing is science and you have to get the recipes right otherwise they don't work. Think of making the pot like cooking and glazing like baking. When you're cooking you can go freestyle, throw some things together, experiment as much as you like, taste as you go and change things. When you're baking you follow a recipe or else. Which doesn't mean you can't experiment, and I do, often. But experiments are done in small scale to test the glazes first rather than just using them on bigger pieces and crossing your fingers. My main glazes are a metallic glaze based on the FirstFive Gold recipe from Joe Thompson at Old Forge Creations, a cobalt blue, a glossy clear coat which I use on porcelain and a bright orange, which is coloured with ceramic stain.

Pottery nerd question: my current wheels are a Roderveld Max 30 which I love because it's easy to clean and solid as a rock and a Shimpo Whisper which is incredibly quiet, as the name suggests. The current kiln is an electric 120 litre Skutt. I use various clay bodies, including Valentine's B17C as a regular stoneware, Scarva PF680 smooth black (it's not very smooth tbh) and Royale Porcelain when I'm feeling fancy. I use the Hartley and Noble Russian Doll batt system, which is excellent. Other stuff comes and goes (actually it just comes, I'm a pottery tool hoarder), but I would be lost without the Mudtools Do All trimming tool. And like most potters I also possess an insane number of buckets.

Most of my work is decorative and not meant for food, and the metallic glaze I often use is not classified as food safe (although if you are drinking from a vase I would suggest you might look at some of your life choices). Although not food safe all my pieces are perfectly safe to handle.

One of the first things I ever made out of clay at The Ceramic Studio in Kent was a stamp, so that all the students' work could be identified. I found a screw and then another square thing and stamped them into clay. I still have that stamp and use it from time to time and a stylised version of it has become the logo, designed in Keynote since I'm not a designer and made into a vector file by my teenage son who is. I have since had the logo turned into a plastic pottery stamp and an ink stamp for bags etc.
