20/11/25 So far, the oven has hardly developed any cracks in the plaster, apart from a few tiny hairline cracks that disappear again after cooling down. Embedding the glass fiber fabric in the plaster was a good decision.
I always applied thin layers and waited a long time between coats, which is absolutely necessary when working with lime plaster.
Next time, however, I would start all the work in spring. :)
This is definitely advisable for bricklaying and plastering work in order to remove all residual moisture from the bricks, mortar, and plaster.
Insufficiently dried materials can lead to high tension and cracks (due to rapid evaporation) when making the first fires.
