NatashaMM Posted May 3, 2021 Report Share Posted May 3, 2021 My husband is carving a block of marble, producing marble dust - as well as a sculpture! I am wondering if there is a clever use for the dust in ceramics. I've stuck some straight on to a test tile and am contemplating wedging some into a lump of clay. Has anyone perchance got any experience or suggestions? Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted May 4, 2021 Report Share Posted May 4, 2021 So a quick google search suggests that marble starts its geologic life as calcite or limestone, but gets crystallized with heat and pressure. I have no idea how the crystallization process would affect its availability in a glaze melt, but there is this entry on Digitalfire for limestone. I was interested in the bit at the bottom of the page about what happened with the clay/limestone mix being fired to cone 6 and what happened when it got wet. https://digitalfire.com/material/970 That said, it may not behave like limestone, and tests could prove interesting.

NatashaMM Posted May 4, 2021 Author Report Share Posted May 4, 2021 Thank you, Callie, I knew marble is pressurised limestone but didn't think to look it up. I have seen elsewhere some industrial experiments successfully incorporating marble dust into for eg roof tiles at 20%, so imagine the effect with limestone doesn't happen with marble. Mostly I wondered how to use it to create an interesting surface texture and whether anyone has been doing this. Link to comment Share on other sites More sharing options...
Chilly Posted May 4, 2021 Report Share Posted May 4, 2021 Sounds interesting. Please let us know how you get on. Link to comment Share on other sites More sharing options...
