red quarry tiles for oven

I've been looking high and low for these tiles for a couple weeks and finally found some.


They are 6" x 6" unglazed straight from Italy, the cost was roughly $3.12 per square foot(ie 4 tiles).


I purchased them through a wholesaler named Olympia Tile, they are scattered throughout Canada and have some stores in the US as well.

Why did you need red quarry tiles?  I understand the thermal mass/lining the oven thing, but why this specific?

To the best of my knowledge red quarry tiles are the most natural and are food safe to use with cooking.


The glazing on tiles is a health concern, as well as most ceramic/quartz/granite tiles.  There are many posts on TFL discussing this topic.


The other option was to buy a Fibrament stone, but they are very cost prohibitive for me at this point in time.  Coupled with the fact that I inject steam with my oven when baking I didn't want to ruin a $90USD piece of stone.

I absolutely agree with the health issues with glazes.  I am surprised that granite would provide health issues.  I am curious, I will go find those historical postings.


Out of curiosity, how are you injecting steam into your oven?  Is this into a standard home oven?

I made it sound much more elaborate than it really is.


I preheat my oven to 500-550 with an empty broiler pan in the bottom.  After the preheat I dump in a cup of boiled water.  I also block the vent with a dish towel to keep the steam in the oven.


I had a spritz bottle, but honestly between multiple oven openings and the work required, it doesn't add anything.

The federal government has concluded that the tiny chrystaline rock particals found in granite can cause lung cancer. The National Toxicology Program listed crystalline silica dust - a by-product of mining, quarrying, foundry work and stone processing - as a "known human carcinogen."  Rutland Herald May 28, 2000 By JOHN DILLON Staff Writer.


My husband is a sculptor and will not use granite for his sculptures for this reason. This may be a jumping off point for further investigation into using granite for oven tiles.

I haven't had much luck with quarry tiles.  They crack easily (at least in my oven).  Also, they don't provide a lot of thermal mass.  I recently got a Fibrament stone.  I haven't heard anyone complain about damage from steam.

I've had "good enough" luck with quarry tiles, but they also tend to move around when you put bread on or off them.  I know FibraMent stones are good, but I've also heard of people using even thicker kiln shelves, cut to fit of course (fits oven with 1" or more gap around perimeter.)  Has anybody here used kiln shelves?

and baking, unlike sculpting, cutting, sanding or otherwise modifying the granite where dust or fine particulate is being generated, presents no health risk. Proper masks and cutting techniques, like water saws, mitigate the risk for those who are engaged in the latter.


For the record, any mineral material with a certain particle size and ratio of length to width, otherwise known as an aspect ratio, e.g. asbestos, is a hazard. There is nothing chemically innate to granite that makes it a hazard; if so, there is no way that it would be used as a common countertop material.
