Glazed Ceramic Knobs

Well, these have turned out pretty good. So pleased with the outcome. Some have now gone to a new home but there will be plenty more to come !



Just love the way glazes have that powdery pastel look before firing.


After a few test pieces I continued to glaze the cupboard/draw knobs, using 3 coats of brush on glaze and no clear glaze. Plugs out for the first 2 hours and fired  to 1105c, cone 03 with a 15 min soak. A test piece fired to 1140c proved to fade and blur the colours.

 These are some samples of the metalyk bronze on-glaze  I used on parts of the mushrooms and faces.
The effects of layering the bronze onto different colours, looks good over the darker colours.


I used the bronze onglaze around the hairline and at the base of the knob to give a nice neat finish.



I added some bronze onglaze detail to add more interest to the mushrooms.



The hats reflect the cowboy theme.

Ceramic Knobs

Well, I have been busy ! It all started when a furniture designer The Shabby Chiffonier asked me to create some draw knobs for some furniture she was designing. She was inspired by Alice in Wonderland and Mackenzie Childs designs. So off I went collecting and pinning designs in this theme until I came up with some unique designs.


I then researched the different techniques in making ceramic draw/cupboard knobs and decided the best technique to use would be wheel thrown in high fired white earthenware grogged clay ( K112 ).


 Each thrown knob was then hand sculpted. I made the small fairytale mushrooms separately and joined them onto the main body of the knob.




The hats were totally hand sculpted, no wheel work necessary. 


 The swirly pattern was created by using a hand held sculpting tool when the clay was leather hard.



The faces and hair were carved out of the wheel thrown knobs. One male and one female face because they will be used for 2 bedside cabinets, his and hers.


I inserted a deep hole in the underside center. Taking care not to distort the ball shape. The apertures were made 14 % larger to allow for shrinkage during firing. This allowed the bolt inners to sit comfortably after firings. I used my white pencil measuring 715mm. inners measured        .




I measured the bolt inner with some digital callipers for precision measurements.

Once thoroughly dried they were bisque fired to 1004c. Plugs out for the first 5 hrs. No soak
