One of the most exciting revelations from this term has been to be involved in the process of “Raku” an exciting ceramics firing technique. Using different glazes to achieve different outcomes.
On this occasion I used a copper and crackle glaze,resulting in my amazing pot, that’s never going to be out of my sight.Not least because my tutor was Mr “Bruce Chivers” . An expert in “Raku”. Process
1. Use bisque fired pots 2. Apply glaze 3. Pots are put in the kiln and bought up to glaze melt, 1400-1832F. 4. place pots in dustbin (reduction chamber)with combustible materials. Wait for the dustbin to burn out and cool. Remove pot.
Because Raku is a low fire technique, the resulting pots are not especially durable, but I think you will agree “Beautiful”.
2. Screen Printing,
Fabulous playtime, and wonderful process and where you get a chance to be artistic.
1. Pen and ink drawing – Jelly fish
2. Photocopied in black and white on to acetate
3. prepare screen – coat with light sensitive liquid
4. Photographic exposure in a darkened room -with an ultra violet light box that incorporates a vacuum. The vacuum holds the photocopy in contact with the screen against the light source. – design will be transfered to screen
5. fabric – pinned tightly to a prepared surface
6. Dyes – using a coating blade (www.solgel.com)
7. Rinse – screen must be washed off after printing – a shower unit can be used.
8. hang print out to dry
3. Two Part Plaster Mould Making
This was a very interesting process, although in my completed project I only used a one part mould (flood mould) used to make wide mouth bowls, but the process is the same.Tony Weavers, explained this process using clay.
1.Select Item to be moulded
2. Prepare frame /mould – x 4 sides, creating walls, tightly held together & sealed all around so slip cast doesn’t leak.
3. Prepare slip cast (plaster) – pour half way up the frame – make a funnel to allow slip to be poured in. Leave to dry – add rounded indentations with corresponding protuberances on the opposite face of the adjacent piece. Dry till leather hard
4. Repeat the process until you have a two- part mould
