Hands On Posted April 23 Report Share Posted April 23 Hello All I am mixing up some shinos and looking for a classic white high alumina shino- the receipe ( Jihn Britt) requires a Alumina Oxide (A-12) cant seem to find that here in uk is it a Calcained Alumina hydrate? cant seem to find the answer online. Thanks all Quote Link to comment Share on other sites More sharing options...
Min Posted April 23 Report Share Posted April 23 If you calcine alumina hydrate to drive off the H2O you will be left with alumina oxide. (approx 35% LOI from it) Whether or not the mesh size is different I don't know. I found a pdf with mesh size of various aluminas here if you want to compare it to your alumina hydrate. If you don't calcine it there might be issues with both the glaze lay down and/or gassing off (plus the obvious difference of adjusting the recipe to allow for the LOI if you don't calcine it).
