This is an intensive firing course, where you will learn how to fire your work (your own or provided by us) using saggar, raku or barrel firing techniques over two days. The workshop takes place at Abi's beautiful studio on the edge of Dartmoor in Christow, Devon and is run by Abi Higgins and Alison West
Christow is a village in the Teign Valley on the eastern edge of Dartmoor National Park with easy access to Exeter.
Raku Firing. The name Raku means ease, pleasure and enjoyment. With its roots in Japan, the technique has altered over the years to produce some of the most interesting and gorgeous effects found in ceramics. Intensely hands on, it is sheer pleasure to experience the low-temperature, fast-firing process which involves removing pottery from the kiln while at bright red heat and placing it into containers with combustible materials.
Saggar Firing was originally developed to protect wares from ash- slagging and flame-flashing in wood firings, but in contemporary use, with clean-burning gas firings, the process is used in exactly the opposite way: to contain fumes around a pot so that the pot picks up colour and pattern from the fumes. Saggars are the lidded containers used to contain and isolate pots during a saggar firing.
Barrel Firing developed as an alternative to long pit firings with the advantage of getting to high temperatures making it possible for added oxides, carbonates and copper wire to produce stronger colours. A steel barrel is loaded with sawdust, straw and wood together with metallic colourants and pots and fired over several hours.
Over the weekend you will –
• Learn how to prepare your pots for firing.
• Learn how to load and fire a raku kiln, load a saggar and fire in a gas kiln and pack and fire the barrel.
• Be introduced to wax resist techniques, sacrificial glaze (naked raku) and reduction glazes with demonstration of applying terrasigillata slip.
You will be instructed by two teachers, so plenty of help and advice throughout the weekend.
Bisque fired pots can be provided at extra cost or bring your own bisque fired masterpieces. Details of how to prepare and burnish your own pots are below.
THE COST FOR TWO DAYS IS £280.00
CLAY AND BISQUE FIRING
Remember that we will be firing up to 40 pots so it is really important that you keep to the guidelines below so that everyone gets a fair share.
Maximum of 8 pots each no larger than 15cm in diameter and 20cm tall and smaller if at all possible. In particular we cannot manage flat pieces such as tiles as they take too much room in the kilns. No jewellery please. We will provide a few extra pots at a small extra cost if it is not possible to bring your own.
Any well grogged clay which resists thermal shock is suitable and we find Ashraf Hanna usually works well. You will need to biscuit fire all your pots before you bring them. Do make sure you don’t trap any air in your pots when making them as raku firing is much more rapid than normal firing and will expose flaws in making sometimes resulting in pots blowing up in the kiln. Also, if you make fully enclosed forms like pebbles, make sure that the air escape hole is larger than normal i.e. not a pin hole.
Fire your pot[s][ to a maximum of 980c degrees. Anything higher tends to destroy the burnish.
PREPARING THE POT SURFACE
Get the surface of your pot as smooth as you can and then apply a fine grained slip at the leather hard stage. Some people use a porcelain slip. We use a slip composed of 50% body clay plus 50% porcelain. Sieve the slip at 200 mesh to get it as fine as possible and then apply as many coats as you can. Terrasigillata can also be applied at leather hard stage should you be familiar with the technique. .
Allow the slipped pot to dry to nearly bone dry. The actual dryness which suits your personal technique varies from person to person and you can only find it by trial and error. Try on a relatively hidden part of the pot. If your burnishing leaves unsightly indentations, your pot isn’t dry enough. If burnishing doesn’t produce a shine and leaves the surface dusty, your pot is too dry. See below for a possible way out.
Now you’ve got the perfect dryness[!], burnish by smoothing the whole of the surface using your chosen tool. Different tools are used depending on your preference. Some people use the back of a spoon, some use a polished pebble. This should give you a smooth, polished surface. You can repeat the burnishing to improve it if you wish. It is worth finishing the surface by rubbing it with a thin plastic bag stretched across your finger.
If your pot was too dry you can try moistening it in sections by dipping your finger in water, smoothing that on your pot a section at a time and then burnishing that area.
