Rocket Stove / Tandoor Oven firing the clay

A question i have as i know almost 0 about pottery is this. If i built a Tandoor Oven / Rocket Stove hybrid would burning coal initially produce the temperatures needed to fire the pottery? I know it technically needs to reach close to 2k farenheit (for the clay i would use)  would this be achievable or is there another material that could achieve said temperatures?

Any info to assist the ignorant would be appreciated

Danke

Are you asking whether you would be able to fire the clay by burning a fire in the rocket stove/ tandoor oven?  And are you talking about building a hybrid rocket/tandoor?  The hybrid idea strikes me as interesting, not sure about how well it would work, but interesting.

Typically, pottery gets fired in a kiln - there are loads of different traditional and modern kilns for firing pottery.  Some are electric, some propane fired, traditional versions have been wood fired for centuries.  

Doing a quick google search, I would expect to make a tandoor oven from terracotta and fire it at about 1,000, not 2,000.  2,000 is a firing temperature for porcelain/ceramic - china.
