The collection of the District Museum in Sandomierz holds a previously unidentified and unpublished triangular ceramic crucible. After at least fifty years since its acquisition, it was possible to obtain detailed information about chemical composition presumed use past. Based on analogies from Central Europe, is date typologically 14th-16th centuries. stamp mark bottom crucible points Tulln Au...

in this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. a synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°c and 1600°c. it has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°c. in this case, capillaries are the ...

domain of experience (e.g. hayat tadını görmek “to taste/experience life”, (lit. “to see the taste of life”). Turkish verbs do not extend their meanings to all abstract domains Croatian prefixed verbs do: they do not share meanings with Croatian verbs pokušati “to try; to attempt”, okušati se, okušati se u, okušati se kao “to try (out) (as)”, nor can they be related to the abstract domain of te...

DRI production in tunnel furnaces sometimes encounters an incomplete degree of reduction. A model is required to tackle heterogeneous reaction rates, crucible heat transfer, and oxide morphology. Herein, a three-phase proposed based on mass conservation kinetics, describe the reduction hematite magnetite crucibles. The was implemented via Fortran program using finite volume discretization, resu...
