I’ve wondered for awhile whether my old electric kiln could manage the long slow heat soak required for glass casting. Flat kilns with heating elements in the top are recommended for hot glass work because a) a lot of glass work is flat (plates, windows) and b) heating large flat pieces of glass from the [...]
I make slip cast stoneware, porcelain, and kiln cast glass. I use old plaster molds found in garage sales, freecycle, and curbside. I make my own traditional poured plaster molds from found objects.
I also design 3D models in CAD software and make plaster molds from the models using a 10 year old ZCorp 406 3D powder printer. Mold making is an intermediate step: my goal is to eliminate the mold and print directly in clay and glass.
In the spirit of consolidating my online identity onto a server I control and actually own the content, I’m repurposing dannythorpe.com to include non-software stuff I’m into as well as the software and technology related stuff I’ve posted here for years. I have been intending to build separate sites for my various fields of interest, [...]
These two bowls are made with the same stoneware clay, the same glazes, and the same firing temperatures and schedules. They were fired in the kiln together, side by side. And yet the colors are so distinctly different between the two. Why? The only difference between these two pieces is the thickness of the glaze [...]
I’ve been trying to get a nice clean rim impression from my “circle dot” pattern wheel for ages. We don’t have failures, we just have lots of practice and educational opportunities. Clay too wet/sticky, too much pressure, not enough pressure, uneven distance from the rim, and worst of all the tail not meeting up with [...]
As I was finishing this bowl with a saturated iron teadust glaze I idlely swirled a finger around in the goop puddling in the bottom of the bowl. Who doesn’t enjoy a finger swirl in goop every now and then? I didn’t realize my brief moment of doodling would create a distinct indelible pattern in [...]
The blue “wisps” in this piece are very hard to see in these photos, but jump out and dance in direct sunlight. The shadowy sprites are the by-product of an uncharacteristically gluttonous glaze interaction. This black base glaze has a tendency to swallow up color that is put over it, but for this particular top [...]
The almost fabric texture on this mug is an example of glaze thickness sensitivity. This teadust iron glaze (a form of tenmoku) forms a creamy base color in thicker areas, and a dark brown in thinner areas. The fabric like texture is the result of brushing the glaze on in multiple layers, each layer perpendicular [...]
