Types of Clay for Bonsai Pots
Hi Everyone
I'm new here, first I'd like to say how amazed I am by some of the pots that others have posted on this forum; they are magnificent.
Now, onto my questions. I wish to have ago at making some bonsai pots; I've been practicing bonsai for a few years, and I've decided its time to try some pots. My Grandmother teaches pottery, and has done for many years, but both her and I are at a bit of a loss as to what type of clay would be best for making bonsai pots with. I live in Australia, and realize that the exact types of clay many of you use may not be available, but can you give me some pointers as to the types of clay that are suitable? some general discriptions, as well as some ideas as to mesh size, and other technical information would be most helpful.
In case it is relevent I would be focusing on shohin sized pots and smaller.
Any help you can offer would be most appreciated

tuscanpistoia,
The one thing that you need to look for first in a clay is one that will vitrify when fired at the temperature you are capable of reaching in your kiln. If the clay absorbs moisture then freezes, the pot will break. Color and texture are important as to the esthetics of the pot, but are things that can be altered in one way or another as you grow in you craft.

Tuscan-
For tropicals, any temp range is suitable, as they won't encounter freezing temps. The lowest temp for all season pots is probably cone 5 with a clay that vitrifies at cone 5. I like to take cone 10 clays to cone 11, and I have friends who take cone 6 clays to cone 7 1/2 to 8 in order to vitrify the body to handle the weather. Your grandma should be able to sort it out for you!

Re: Types of Clay for Bonsai Pots
Bonsai pots are most often used to display plants shaped and styled to look like small old trees.In some cases,these miniature trees are very old, sometimes hundreds of years.Bonsai pots and bonsai soil are inter-related to each other and they are dependent to each other.These two parts of the bonsai care are most important in growth of healthy and beautiful bonsai tree. Pots drainage system and soil quality leads to growing and making of bonsai. So, the bonsai pots and soil takes important parting bonsai growth.

I've done a number of things with Standard Ceramics #507 "Warm Brown." It's a prepared clay that fires at cone 10.
This is about a 9 inch (23 cm) round in 507; the inside bottom is unglazed, the outside has something the school studio calls "peach black" which is a sort of semi-transparent glaze that's mostly clear except over rough textures. (Cone 10 reduction fired.) (The top rim surface had some matte black brushed on, in addition.)
I love what it does salt fired, but don't currently have a place to do it:

Salt / Soda firing is amazing, very toxic and it eats your kiln up, but still amazing I have never seen any salt / soda fired Bonsai pots, wonder if any bonsai potter does them?

Re: Types of Clay for Bonsai Pots
Hello dear all
About the salt firing ??
There are 2 potters i know of who do it sometimes.
Horst H. (Austria) and Rene L. (Belgium)
And i did it
In a salt/wood kiln , reduction and a lot of wood pushing
into the kiln hour after hour to reach 1240*C in the night !
It was great fun and hard work.
Here is a pot from that kiln.
Also did it in electric kiln , but than You have to
built a plate, dome and little cups , to protect the cantal wires from been "eaten".
Plate to put the pot on,cups to put the salt in , dome to put over pot and cups.
Did some bonsaipots , sorry have no pictures of them.
Just this picture of electric/salt little pot firing
Kind regards
