This paper examines construction of the Theophilus glass painting kilns today according to the descriptions by Theophilus from 12th century in "Schedula Diversarum Artum".

The first Theophilus glass painting kiln was built by Estonian Academy of Arts glass students in 1997. This fabulously simple and transportatable kiln type was easy to build as it was exceptionally well-described by the Theophilus. The same could be stated concerning the firing process, which in practice was incredibly similar to the description. Indeed, the flames begin to lick the glass in the kiln!

This armful size of the kiln allowed the medieval glass painter to work anywhere. The kiln is quite durable and transportable, but it is also easy to build a new kiln if needed.

By now there around ten kilns of such type have been built in Estonia. Experience has given an opportunity to modify the medieval kiln type, as to the choice of materials, construction tools and functioning.

Students think that it is the world's most ingenious glass painting kiln.
