• Zvinofanira kurangarirwa kuti ibwe ane porous marongerwo decoration, zvinofadza ziso, mumwe Wedding ruvara chinowedzera kusikwa yepakutanga zvakagadzirwa uye mukati negadziriso mumba, kana kuti France, pasina zvimwe upfumi vari kumugumo.

M15 - ndiwo hachizi rakushnyaka ibwe, iro rine hwakanyatsorwisa pasi arambe achirema, mukuru porosity, simba. Maitiro ruvara, kazhinji akacheneruka yero, mukurumbira zita - zheltyak. Muzviitiko zvokuva kuwa kana kwechirwere, rakakamurwa zvitatu kana kupfuura zvikamu. Rinoshandiswa pakuvaka fenzi, dzimba, chimwe-storey zvivakwa.

M25 - ndiko rakushnyaka mucherechedzo, iro rine yepamusoro arambe achirema, yakaderera porosity, simba, tichienzanisa chete chiratidzo M15. Nokuti muchiso ichi kunoratidzwa ruvara - chiedza tsvuku.
