Wood fired pottery kiln question

Hey y'all I really want to get much more into pottery this year.  It seems my property is on a creek which was named by the local tribes for its fine, white clay.  I've done some terracotta type pottery when I was younger, with low firing temps.  But, we used to have several local potters who made stoneware using wood fired kilns.  They fired in huge batches in "groundhog kilns".  I don't want to go as large scale.  I would like to use wood though, in a simple backyard kiln if possible.  Can anyone give me some smaller kiln designs that would work or advice on glazes that will work at lower temps? If I recall correctly, the pit firing style I learned in summer camps and such we could hit about 1,400F max.  Just looking online, it seems like most commercial glazes need a much higher temp. For glazed stoneware, it looks like I will need to get over about 2,100 F or so.

This looks helpful - good luck, any kind of pottery needs it

I built a kiln roughly following this design. Mine is maybe 1.5-2 times the size, and I used rebar for the grate because I'm not as much of a purist as the guy in the video.

The hardest thing about it is not accidentally firing too high or too quickly, which can cause the pots to crack and/or melt. I have found that it's a bit easier to control if I limit both the air intake and output (I just put a metal trash can lid partially over the top of the chimney, and another scrap piece of metal in front of the intake). I have a thermocouple stuck through the door and I watch it constantly throughout the firing, trying to stick to my intended schedule of target temperature. Fiddling with the airflow can have counter-intuitive effects on temperature sometimes, but eventually I worked out a rhythm for it, and I can keep the temperature slowly rising without too huge of swings when adding fuel.

Low temperature glazes are tough to make from raw ingredients, but they are available commercially. There are a bunch of technical reasons that higher temp glazes are much more common. Also there are plenty of practical uses for un-glazed low-fired pots.
