I need help for the mortar because I cannot find fire clay in my country. Is there other alternative for the mortar?
i know that old ovens were build using lime but dont know the mix

It's been discussed, but I don't know if it's been done.

Google

Have you tried pottery suppliers? Refractory suppliers? Fireclay isn't a rare substance.

when building my Pompeii, I used the poor man's mortar which worked a treat.
When covering the superwool insulation with vermiculite cement, I added some fireclay which made the mix easier to work as it became much stickier.
I would (in your current situation) use the poor man's mix but leave out the fireclay. It may not be quite as good but there are a lot of houses built with this mix (cement and lime) that are still standing 60 - 100 years later.

Cheers.
