You are right Gene, but i can try to clean it with brass brush. But over time and heat this side can release small particles.. for 90% sure.

Neil, i will make block stand out of Ytong by Xella - Ytong
Something like this - Grill z bloczków YTONG - YouTube

also thinking about Xella products for hearth insulation.
But for sure block stand will be min 100cm high.

Update guys...
i have bought 20cm width YTONG bricks (one palette, 42 pcs, 120eur, 200x249x499)

Plan was to make 4 layers


but it was too high (not too mention i was needed to make 20cm hearth), so after we were done we have took 1 layer off, and this is what i have now

just ordered Ytong Reinforced Lintels to make a hearth


250x249x1500 with 22 kN/m

and thinking to cover it with Ytong Multipor (R=1,11 m2.K/W for 50mm thinknes and R=4,44 m2.K/W for 200mm)

Update:
thermal conductivity of
Ytong Multipor λ = 0.045 W/(mK) (no temp data)
Morgan Thermal Ceramics - Ceraboard 1260 λ = 0.08 W/(mK) (400C), 0.11 (600C), 0.15 (800C), 0.2 (1000C)
Unifrax Fiberfrax 1260 λ = 0.09 W/(mK) (600C), 0.13 (800C), 0.17 (1000C)
FB from Forno Bravo has λ = 0.085 W/(mK) (400C), 0.132 (800C), 0.189 (1000C)

For cutting 9.5 in bricks in half i put 10 bricks on a 2x10 and set up a board on top of them for my fence and cut them with a 7.5in carbide blale , cut both sides about 1/2 in then use a hamer to split them .
Once you set up your gig it goes real fast. Finished my pompaii this summer, and lovin it

Wow - several flavors of cal-sil as standard building materials. In the US, for commercial construction, we have duct board for restaurant grease ducts and elevator shafts and the like, and industrial/refractory applications. That's pretty neat!

They sell the AAC Hebel blocks, but they're not common here in the northeastern US. The Hebel US site doesn't mention the cal-sil panels/bricks at all.
