Materials: Commonly made from clay (various types) or ceramic. Unglazed pots are frequent, especially for certain tree species, as they allow the soil to breathe. Glazed pots are also used, often for flowering or fruiting bonsai.
Shapes: A wide variety of shapes exist, each with its own aesthetic and suitability for different bonsai styles. Common shapes include:
- Rectangular
- Oval
- Round
- Square
- Hexagonal
- Octagonal
- Informal/Freeform
Glazes (if present): Glazes tend to be subtle and natural in color. Earth tones (browns, grays, creams) are common. Blues and greens are also seen, but usually in muted shades. The glaze should complement, not distract from, the tree.
Decoration: Some traditional pots have subtle decorations, such as:
- Incised lines or patterns
- Relief carvings (often of natural scenes or Chinese characters)
- Applied clay ornaments
Feet: The pot usually has small feet to lift it slightly off the ground, improving drainage and air circulation.
Size: The size of the pot is carefully chosen to be in proportion to the bonsai tree it will house.
Origin: Many highly prized traditional bonsai pots come from Japan or China, and some are quite old.
