All the required work steps and gadgets for making an oval bonsai pot with a rim are shown intimately in the photos below.
A location of pottery tools.
A paper sample is created for the underside form and ft of a pot.
The clay slab for the underside of the pot is ready.
The paper sample is applied.
The underside, the walls, the rim and the ft are minimize from the clay slab.
The underside and the wall aspects are ready for joining them together.
Dry clay is pulverized.
The pulverized dry clay is mixed with water and stirred to make slurry.
The slurry is brushed onto the roughened outer limits of the underside.
Now the walls are mounted.
The junctions are smoothed with a spatula.
On the within a clay coil is pressed into the pot to stabilize the junctions between bottom and walls.
The within of the pot is smoothed with a spatula.
A portion of wood is sawed off at the specified angle.
The puny wood block serves as a gauge for the walls.
A finer gauge is sawed from skinny plywood. It serves for developing an even profile of the walls.
The wood block is dilapidated to press a fitted clay band to the pot.
The finer gauge is dilapidated to form the walls and the band.
The top of the wall is minimize at an even hight.
The rim is hooked up.
The rim junction is smoothed on the within.
The pot is grew to alter into the other plot up and further clay is modelled onto the junction between the wall and rim.
The animated edges of the rim are rounded.
The drainage holes are pierced into the underside of the pot.
Fixation holes are drilled.
The outside of the clay is smoothed with a moist sponge.
The ft are connected with the reduction of slurry.
Four puny clay cubes are connected to protect up the underside from sagging accurate by the drying process. The pot must dry slowly on legend of in every other case the pot will destroy.
The pot has been bisque-fired after drying. Now the glaze is applied. The coloration will swap fully accurate by the glaze-firing process.
Glaze applied.
The pot is ready after glaze-firing.
A red hawthorn used to be planted into the pot.
Photos of the kiln
For firing the created pots after drying, a assorted pottery kiln is required. There are varied assorted kiln kinds, shapes, sizes and firing systems, worship electrical kilns, gasoline kilns and woodfired kilns.
Most ceaselessly the bonsai tree pots are fired twice. The first firing process, called bisque firing, takes space at approximately 800 – 900° C. Afterwards a glaze will also be applied, if desired. The 2nd firing process (stone ware firing) must poke up to 1200 – 1300° C in show to protect up out perfectly frost-resistant pots. In the next photos you gaze Erwin Grzesinski’s electrical kiln.

The kiln’s controls.
The underside layer of pots and glaze assessments loaded into the kiln for firing.
A fireclay board has been added and the center layer of pots etc. is positioned upon it within the kiln.
A 2nd fireclay board has been location in and the terminate layer of pots is positioned on it. The within dimensions of the kiln are 21″ by 21″ (54cm x 54cm).
Sooner than and after glazing, three examples
Glazes are a charming topic within Bonsai pottery. Newbies will spend ready-made glazes whereas mavens protect to manufacture glazes of their very own. First and predominant it’ll be amazing that the coloration of the applied glaze has most ceaselessly any resemblance to the glaze coloration after firing. The glaze needs to be appropriate for the firing temperature for reaching the anticipated outcomes. A first charge records of chemical processes is important.
The following photos show about a examples of glazed pots earlier than and after glaze firing.
Documented by Erwin Grzesinski and written by Heike van Gunst. Erwin Grzesinski, born in 1954, studied architecture and in his expert lifestyles restored churches and – among other things – worked in the constructing materials business. Moreover artistic spare time actions worship carving soap stone figurines, he has been making Bonsai since 1995 and Bonsai ceramics and accent pots since 1996. Over time pottery turned into extra eminent and in the meantime Erwin has a substantial series of possibilities among Bonsai fanatics and artists from Germany and abroad. As he mostly works on show and cannot produce tremendous numbers of pots due to restricted capacities, his pots are in general no longer stumbled on at Bonsai traders (net net page). Heike van Gunst (from Hamburg, Germany) has been rising Bonsai for extra than 30 years. She has obtained manifold abilities in training and caring for various species and has developed a ardour for Bonsai pots and mask. Writing and translating Bonsai articles and Bonsai e-book translations are her particular topic.
