Re: UK Suppliers for Fireclay (again...) Hi Peter,
Hi, I'm about to start the dome , and would really appreciate some advice on the mortar to use. I've had no luck with fire clay. I have an 8 inch hearth - 4inch concrete and 4 inch vermiculite and concrete. I've laid the oven base using fire bricks secured using XL fire cement - this is a pre-mixed cement available in 2kg tubs - a few have gone under the bricks!
I was recommended to use 'Ciment Fondu' for the dome as it copes with high temperatures rather than fire clay. I have phoned around 25 building suppliers, fire stove shops and art material shops(it's used in sculpture) in the last couple of days - but no luck. So I'm planning on using Portland cement, sand lime and I've also picked up granite dust aggregate - I'd really appreciate any advice on ratios - especially the granite dust - will it make any difference to the heat retaining/coping properties? - Cement fondu is made by Portland cement - i think I have the contact numbers if you're interested - I found that because I only wanted 100kg I couldn't get anyone to order it for me. Thanks |
