    Re: My Wood fired Redux

    Slurried the the four finished pieces with white portland/polymer mixture and didn't really like how much it contrasted. So I sanded them down with 70 grit diamond pads to open the concrete up, and then re-slurried with cement that was 1/3 grey mixed 2/3 white. I like the toned down look better so this is how the next four will be done too.

    Here is the first slurry, sanded to 600 grit. They are dark because of the water, the second to last pic is closer to what it would look like dry...still too much contrast for me.

      Re: My Wood fired Redux

      This is what I'm going with. These were sanded today, and placed on the base to check the color. It looks close to the granite, and you are only going to see the edges after the next layer is installed on top of these. The top layer will get a technique called Scagliola, which will add subtle veining. Then I'll fill the pin holes with the slurry to match the edges you see here. That's the plan anyway. The last pic shows the joint spacing...I'm just putting some Lexel in between the pieces, no cementitious material.

        Yeah I know, the arch looks horrible. But when the vent goes on, you will only see 3/4" of the intrados...so there you go.

            I also unmoulded and slurry coated 4 more watertable pieces today. Yet another design change...I eliminated the second layer, and I'll make up the height difference at the oven vent by carving a granite landing to go with the arch.

              Looks great. My interior arch looked like crap too, until I trimmed it and fitted the smoke chamber. The first interior arch, for that matter, I knocked down while cleaning the interior and had to rebuild it completely.

                I almost grabbed my makita with a surface grinder to smooth out the arch, but eh...I seriously doubt it will be an issue, when the vent goes in. Plus the outside granite arch will have clean lines and I think the eye will be drawn to that. Or I'll just reach in with the grinder and have at it.

                  Mine is offset so it looked pretty funky when built. I cut it flush with the barrel to facilitate the vent, even though it is all covered up. The left side is flush with the vault, the right extends 2-3 inches above it prior to cutting it off.

                    I did 45 the upper half of the arch on the interior face to help with the draft, worth doing if you don't want smoke stains.

                      That looks fine to me!

                      I knew going in that it might look weird...turning an arch with square units never looks good to me, but I didn't feel like all the cutting was worth it, especially since it will be very low visibility and function normally. I may reach in there with the grinder and bevel my edges on the inside like you did...forgot to do that! Maybe while I'm at it, my ocd will kick in and the arch will get some fine tuning too.

                        On the low done Neapolitan I did, I just ground it after building instead of cutting prior to fitting, it probably worked better that way.

                          Make your outer decorative arch,if you plan on having one, bigger than the entry arch or you will have trouble fitting the door easily.

                            Yes David, that is something I am well aware of....all of the ovens I built in the past have larger vents and outer entries. The granite arch I have mentioned is going to be the outer one...following the line of the vent. It will be around three inches wider than the oven opening.

                                Another fire today, I'm guessing between 400*-550*...maybe a touch hotter. Cracking in the cladding allowed a lot of moisture and puffs of steam to escape...but the joints inside the dome are still tight. I also sanded and second slurried the watertable today, should have those installed by the end of the weekend.

                                Made use of that test panel of perlcrete...holding the heat in the oven after the fire dies down for a long slow cure. V-wiz, this is what I try to do when I cure ovens...and it works well. But as SCChris pointed out, maintaining the temp is a challenge and all day firings aren't always practical.
