Tao Thu Rieng Ban Ko Noi, Si Satchanalai Historical Park, Sukthai Province
This group of glazed ceramic kilns were located along the bank of the Yom river, about 4 kilometres from the Ban Pa Yang groups. About 200 kilns were found in an area measuring about 1.5 square kilometres. 2 groups of kilns have been excavated and developed into site museums. The groups can be categorized as follows:

a) Kiln Group No. 61
This group comprises 4 underground kilns, dug into the river banks. The main products of these kilns were large jars for storing water and dry materials.

b) Kiln Group No. 42
I19 kilns have been found so far in this group. These kilns can be divided into 2 major types: updraft and cross-draft.
Archaeological studies at Ban Ko Noi have yielded much knowledge on the development of ancient ceramic technology at Si Satchanali.
The earliest type of kiln, appearing at Ban Ko Noi around the 11th - 12th century, was the underground bank-kilns. This early type of kiln looked like a round hole dug into the river bank. There were no fired walls to separate the firing chambers from the fuel chambers. Both glazed and unglazed ceramic jars and bowls were produced in these underground kilns. The glazed ceramics produced during this early period were exclusively olive green.
The second type of kiln at Ban Ko Noi was the above-ground type, much larger in size, and constructed directly on top of earlier kilns. Olive green glazed pottery was the main product of these kilns.
The above-ground kilns were constructed of bricks. Glazed pottery produced in these later kilns, dated around the 14th - 15th century, were of various types and shapes. During this time, the glazed pottery of Si Satchanalai, known as Sangkhalok, was exported as far as Japan, Indonesia and the Philippines.
