The second Duomo36 prototype cast in place pizza oven mold is done

The second Duomo mold is done and ready for a trial casting. If you’re reading about this for the first time, the Duomo Series is a family of cast in place pizza oven kits based on high-end castable material and insulators that work in conjunction with a cardboard mold. The molds are 2D CAD designed and they will be cut with a CNC controller laser for a very high degree of accuracy. Far better precision than any precast pizza oven kit. We built the first proof-of-concept mold using shipping boxes we had stored in the attic from our move from…

Dimension drawings for the Duomo Series cast in place pizza oven kits

Dimension drawings for the Duomo Series cast in place pizza oven kits

We’ve finished the full set of dimension drawings for the Duomo Series cast in place pizza oven kits. These drawings show the essential details for each oven, something we called our key Intellectual Property in a previous blog post. The drawings outline everything you need to know about these ovens, from the interior dimensions of the oven width and depth, the thickness of the dome, the oven floor and floor insulation. We also outline the key dimensions, including the oven opening width and height and the height of the top of the dome, along with the inward curve of the…

Our intellectual property

The image above is the full-scale set of drawings for the Duomo36 cardboard pizza oven mold. When I founded and ran a PR and marketing consulting firm in Silicon Valley in the 1980s and 1990s, we worked with a large number of exciting companies full of smart, hardworking people—many of the them engineers. When we started with Alteon Web Systems, who went on to have a home run, billion dollar IPO and was later acquired by Nortel, we were their first marketing staff. The company had 8 engineers, and our primary contact inside the company wasn’t the VP of marketing,…

Duomo mold prototype is coming along nicely

Duomo mold prototype is coming along nicely

We’re building the second prototype of the Duomo cast in place pizza oven kit, and things are coming along very well. We had a full-scale set of drawing printed at our local commercial print shop that we are using to hand cut each of the dome and vent pieces. Each Duomo mold is made up of about 40 cardboard pieces cut from about 14 different designs, including they dome arch, the oven opening arch, the vent arch, all of the cross supports and the covers for the dome and the vent. Cutting and build the first few molds by hand…

Thoughts on dome height

Thoughts on dome height

The internal height of a pizza oven dome is topic widely and passionately discussed. Too high, and you can’t make great Pizza Napoletana. A hemisphere shape won’t reflect heat onto your pizza as efficiently as an elliptical dome, where two focal point focus heat on the oven floor. Too low, and your oven will be inefficient at holding heat. If it’s really too low, the oven opening will be so low you can’t even bake a turkey or a chicken. If your dome is a low ellipse set on top of a steep, perhaps 90% wall (or soldier course brick),…

Cast in place pizza oven (1)—how big?

Cast in place pizza oven (1)—how big?

The first question you’ll need to answer, after you’ve decided to build a refractory pizza oven—either a precast oven kit, a cast in place oven kit, a pre-cut brick oven kit, and a Pompeii oven—is how big? And answering that basic question can be a real challenge. Too big, and you’ll regret the amount of time it takes to fire your oven, and how much wood and effort it takes getting it hot and keeping it hot. You might find yourself not using it as much as you had hoped, because the whole process of using it was more than…

Cast in place pizza oven (3)—the foundation

Cast in place pizza oven (3)—the foundation

A cast in place pizza oven is heavy enough to require a formed and poured concrete slab. It’s also important to note that it’s very important that your pizza oven cooking floor is level (along with your grill), and pouring a level foundation is a good way to start. In our case, we are installing doors in front of both openings, along with a bottom ledge that will keep water out, so we did not design a slight downward slope on our slab to shed water. If you aren’t adding ledge, be sure the gently slope your slab toward the…

The Duomo cast in place pizza oven mold—beta 1

We’re off and running. I built the first trial cardboard mold for the Biscotto di Sorrento Cupola cast in place pizza oven kit a few weeks ago, and I’m going to analyze what I did right, and wrong, and put a plan in place to significantly improve Beta 2. If you are reading about our upcoming pizza oven kit for the first time, the Cupola is a complete kit for building a high-end pizza oven, including the mold and castable refractory material to cast a durable, well-shaped, high quality oven dome—along with the insulation, floor, chimney and door. The key…

Blogging a cast in place pizza oven build

Blogging a cast in place pizza oven build

We’ve broken ground and we’ve staring building a 36″ Biscotto di Sorrento Cupola cast in place pizza oven, using our own pizza oven mold. I’m going to be blogging the construction process to walk you through the steps and provide some recommendation and suggestions along the way. First, let’s start with an image of what things looked like to start. When we bought our house in Alexandria, the house had been vacant (read abandoned) for about 8 years, and the few things the previous owner had done were pretty terrible. The house was originally built in 1780, and added onto…

Pizza Stone vs Pizza Steel vs Pizza Oven Stone (Biscotto)

Pizza Stone vs Pizza Steel vs Pizza Oven Stone (Biscotto)

Pizza Stone vs Pizza Steel vs Pizza Oven Stone—they all sound familiar, but they are three entirely different products, each with a clearly defined target use case. Let’s get into it. Pizza stones usage has moved from people who are serious about making pizza and baking to the mass market over recent years. A pizza stone is typically made from cordierite, an expensive material that is the byproduct of mining for other, more valuable minerals. When most people think about a pizza stone, they’re imaging a 13′ round, or 14×14″ square stone that’s about 1/4″ thick. Some come with a…
