New Kiln 'Tanwen Holy Fire' first firing.
I made the plates in November and tried to get to a Cone 6 in my very old kiln but it just didn't make it so I put them at the top of the new kiln yesterday and used the Ceramic Materials Workshop Cone 6 firing schedule which was 300°c per hour until 100°c below top temp and then 150°c to top temp with no hold and just normal cooling. I filled the rest of the kiln up with other stuff, mostly things I will be donating to a cat charity at an event next weekend. Top temp 1243°c for a hot cone 6. The cone melted onto the shelf so I had to crumble it off. The kiln couldn't cope with the 300° per hour climb after 900°c so I will adjust that going forward. Everything is either x2 or 3 depending on the glaze thickness when I brush it on, with one layer for swishes or top fluxes. So, the plates came out fantastically, Obsidian and Ancient Copper with Seaweed, Textured Turquoise and Textured Kiwi Fruit strips. A few pinholes but these are for me so not a problem. Going to be using this again, they look amazing. Then a range of River Birch and Botz Plus melty cups. Lovely result, very happy. First one is RB plus Text Kiwi Fruit strip underneath, then Honey Flux with True Celadon and Botz Plus over the top half inch. Then 2 Rose Quartz items and only tiny outside pinholes on one - the first one has honeyflux over it with some cinnabar on the outside and botz plus on the edge, and the second has Rose Quartz with Lynette's Opal on it. Then a planter, Obsidian, RHC and Blue Rutile. Then Jane's First Seat in Clay which I made in the middle of winter and only just fired. A few other pieces as well, mainly some cracked glaze tester pots and some pet bowls for the event in plain colours. But apart from the plates - no pinholes at all. Very, very happy with this load.
