Tired of brushing and cleaning the oven floor?
I have just started to use two circular ceramic tiles (the types sold for use in stoves for baking pizza) inside my WFO. After moving the wood/coal to the side I place the tiles on the oven floor and let them heat up for some 15 minutes and then place the pizza. No need to brush and clean the floor and the tiles can easily be taken out and cleaned after baking.

cool idea Karl!

I wonder if a similar concept could be used for those without good insulation under their floor. Place a 2x2 ft square of insulation board with a 2x2 pizza stone (or thicker tile) on top - heat that up and cook on it....

Karl and Christo,
what seems to be the trouble with brushing the hearth for cooking?
Only today, after 1 1/2 hours of a good (but not fierce) fire, my hearth and dome were over my infra red thermometer max (500˚C). I simply pushed the coals back and to the sides and used a banister brush for around 15 to 20 secs to clean the floor. Admittedly it was well worn down (well at least burnt down: and it is not nylon but the old fibre bristle brush) I set it on fire. I removed it, put out the flames and commenced cooking immediately. No 1 pizza in around 1 minute.
Using tiles and/or a pizza stone only limits your use of the whole available hearth area and how many you can handle at once.
Just a thought.

Re: Tired of brushing and cleaning the oven floor?

I never seem to be able to handle more than two pizzas at one time anyway. And for the rest of the cooking everuthing sits in their own pots or jars so no need to clean the surface. For the baking at the end the tiles are equally handy.
When cleaning the floor with the copper brush I have realised that this is probably the action which makes most wear on the floor bricks (over time). It causes pitting in the bricks surface.

Re: Tired of brushing and cleaning the oven floor?

Possibly. But you will need to get the tiles through the oven opening (mine is 46 cm).

Re: Tired of brushing and cleaning the oven floor?
only goes to support my theory of using 3" fired clay pavers for the hearth, much harder and durable for such use rather than softer porous fire bricks!
Mine seem OK (but being second hand and could be 50+ years old) but might be better when made than those of today. Tim has used these in preference to firebricks and has used inexpensive (or even free) common red solid house bricks for his dome.

I'm ok with brushing - I lucked into a long bristled brass brush that seems to work well.

I saw Karls idea as having alternate uses.... even for those with gluten contamination worries, too

Re: Tired of brushing and cleaning the oven floor?
Sounds like a sensible theory Neill. But it is hardly any option form me (or others having used fire bricks in the floor) now.

The point is that the tiles work fine. And can be a good idea also for others. I may return to the "floor brushing method" again perhaps. The errosion on the floor is not my main reason for using the tiles. I just find it practical at the moment.
And this is the home for good (and less good) ideas isn't it?

regards from Karl

Re: Tired of brushing and cleaning the oven floor?
Karl, Most of the pizza stones I've seen have small feet made into the bottom surface of the stone. These feet would keep the stone from having direct contact with the floor/hearth over the whole bottom surface of the pizza stone. It would be interesting if you could relate any problem with how many pizzas you can sequentially bake on your stones. One would think the gap would slow the recharge of the heat but perhaps that is a wrong assumption.

At present when my wife and I have company over we do 6 pizzas about 11-12 inch diameter and if just the two of us, only three. Using our hearth as the baking surface we have little problem with three one right after the other and for six we usually pause between pizzas and I pull coals over the surface after the first three as the pause time may be 20 minutes or so. My fire up time from match to pizza ready is about 40 minutes so my saturation isn't complete but adequate if we are just doing a pizza and a dryout of wood at evenings end.

About the only problem I've noticed is that I am badly scratching the bottom of my SS roaster dragging it over the hearth.

Re: Tired of brushing and cleaning the oven floor?

True. Mine have as well so there is not full surface contact. I have never tried to bake in immidiate sequence. Normally some 10 -15 min in between. I think you are right that the tile likely needs to "recharge" for a few minutes to be sure it is up to the high temperature again. It does not seem to be much of a problem. Usually the floor is on the warm side anyway and the issue is, when baking directly on the floor, to try to avoid the bottom to be burned (i.e. the "wet dough issue").
