How many grades are pipes categorized giving definition and type of colour in each grade?

Pipes are typically categorized into three grades based on the quality of the briar wood used to make them. These grades are:

1. Straight Grain: Pipes in this grade have a flawless grain pattern with straight lines running vertically along the bowl. The color of the briar wood is typically a light to medium brown.

2. Flame Grain: Pipes in this grade have a grain pattern that resembles flames, with swirling lines and patterns on the surface of the bowl. The color of the briar wood is usually a darker brown or reddish-brown.

3. Bird's Eye: Pipes in this grade have a grain pattern that looks like small circular dots or "eyes" covering the surface of the bowl. The color of the briar wood can vary, but is often a mix of light and dark brown tones.

These grades are used by pipe makers and collectors to differentiate between pipes of varying quality and value.
