  • "As this object is "purportedly made from ceramic".... There are 3 ways that I can imagine making it. I don't think the visual speckle effect is painted on. I think it's actually IN the clay.      Solution #1:  Slipcasting... Which is pretty much the same idea as injection molding, it just takes a lot longer...First, a perfectly rendered/sculpted/machined model of the final product would need to be made... Then you'd need to make a plaster mold of that model. In this case, it would likely require a 4-5 piece plaster mold.Then... you'd need to make your "slip" (perfectly homogenous, liquid clay or porcelain)...Then you'd have to color your slip (with certain chemical(s)) in order to achieve the base color (in this case, the burnt orange color is perhaps achieved with an iron oxide). Then, I imagine there to be a second chemical additive (to achieve the black specks)... Crucially, this additive would have to have the property of NOT dissolving and homogenizing within the slip, but would instead, remain separate, much like droplets of vinegar in a jar of oil. As long as the mixture is stirred, there would be a randomized distribution of those elements, within the liquid slip...Then you pour your slip into your mold, and wait. Then wait some more. Once the plaster has absorbed all of the water from the clay, you're left with the perfect copy of your model.You take it out of the mold, carefully trim it up, and you're all set and ready to fire that baby.That's a whole other process, obviously. But whatever chemicals were used to achieve the colors would be susceptible to the conditions within the kiln, and you'd likely get different results, depending upon different firing conditions, i.e. different firing temperatures, different atmospheres, electric/gas kiln, etc.     Solution #2: Extrusion... This would involve using a more conventional (non-liquified) clay mixture. Much as in Solution 1, above, the clay would have to first be colorized and homogenized. Then an additive, like a sand or or stone grit would have to be worked into the clay so as to achieve as uniform a distribution of the particles as possible. Once this clay has been made, you'd need to use an extruding device that matches the dimensions and specifications of your desired end product. You just shove the clay in the device, pull the lever, and out comes your tube of clay. It's kind of like making penne pasta.The tricky part with this technic would be stamping in that logo, without compromising the shape of the tube. For that, you'd need some kind of (probably metal) tube, to slip inside the tube, once the clay has dried.Also, this technique would require a lot of work to make all the edges perfectly smooth and uniform.... and then of course there's the firing process as discussed above.     Solution #3: Press molding... which is basically like a cross between solutions 1 and 2. You make a model first, and then make a mold of that model. Then you use the more conventional clay (with grit added) and put it into the mold, filling it as much and as perfectly uniformly as possible (in other words, no air bubbles)... Let the clay 'set up' and dry a little, take your form out of the mold, trim it up and fire it.[I have a BA in Fine Art, with my emphasis having been ceramics. I have a lot of experience making forms like the one pictured above, and experience in all the techniques in my three proposed solutions. Of course, these techniques were not performed on any kind of industrial scale, so I imagine my solutions to be a little less elegant than what could be made by a company like Kohler... or apparently, Lapka. But, well... you get the idea.Hope that helps!! "
