In cooperation with Ine & Ed Knops, the popular authors of Rakuvaria, we developed two new Raku bodies with the name Rakuvaria extreme in the colours white and salmon.
With "Rakuvaria extreme" are various firing techniques in an open fire possible. Both bodies contain 60% grog of the size 0-3 mm and are recommended by Knops for extreme Raku firing, shaping and firing within one day.
This “rough” clay which contains a lot of grog can still be finished to a smooth surface, using a kidney and a pebble. Firing higher than 1200°C in a wood-firing kiln. After a few hours of cooling, we can see the results: as from 1200°C it becomes a glaze!
Rakuvaria extreme in a microwave and in a warm bone dry state, raku fire in the “hotpot”. From the hotpot, a few minutes into the sawdust, after that cool the piece in water, polish and finish.
