A portable kiln has a set of wheels, a handle and a platform base. The wheels and the handle are attached on a first side of the kiln so that the kiln can be tilted and rolled on the wheels using the handle. The platform base provides a spaced distance between the wheels and the floor when the kiln is sitting upright in an operational position. The kiln may also include a metal outer shell wrapped about an oven portion. The outer shell has a shell sidewall radially spaced from the oven portion sidewall, which forms an annular air channel between the outer shell sidewall and the oven portion. The outer shell has a C-shaped cross-section and it has upper and lower vent openings for the air channel. A hinge assembly allows a lid of the kiln to rest in an open position.

We claim: 1. A kiln, comprising: an oven portion having an insulating sidewall defining an oven space; a metal outer shell having a shell sidewall radially spaced from the oven portion sidewall, wherein an air channel is formed between the outer shell sidewall and the oven portion sidewall and the outer shell having upper and lower vent openings formed therein so that air may flow through the vent openings into and out of the air channel; a control box attached to the outer shell so that the control box does not have direct thermal contact with the oven portion at points of attachment; a set of wheels attached to the control box at a lower portion of the kiln; a handle attached the control box and extending from an upper portion of the kiln; and a platform base disposed beneath the oven portion, the platform base having a height providing a spaced distance between the wheels and a floor when the kiln is sitting upright in an operational position on the floor. 2. A portable kiln, comprising: a set of wheels attached on a first side of the kiln and at a lower portion of the kiln so that the kiln contacts a floor via the wheels when the kiln is in a tilted position and so that the kiln may be rolled on the wheels in the tilted position; a handle attached on the first side of the kiln and extending from an upper portion of the kiln; a platform base extending from a bottom side of the kiln, the platform base having a height so that there is a spaced distance between the wheels and the floor when the kiln is sitting upright in an operational position on the floor; an oven portion having an insulating sidewall defining an oven space; a metal outer shell having a shell sidewall radially spaced from the oven portion sidewall, wherein an air channel is formed between the outer shell sidewall and the oven portion sidewall, and the outer shell having upper and lower vent openings formed therein so that air may flow through the vent openings into and out of the air channel; and a control box attached to the outer shell so that the control box does not have direct thermal contact with the oven portion at points of attachment, and the wheels and the handle are attached to the control box. 3. A portable kiln, comprising: an oven portion having an insulating sidewall defining an oven space; a metal outer shell having a shell sidewall radially spaced from the oven portion sidewall, wherein an air channel is formed between the outer shell sidewall and the oven portion sidewall, and the outer shell having upper and lower vent openings formed therein so that air may flow though the vent openings into and out of the air channel; a control box attached to the outer shell; a set of wheels attached to the control box at a lower portion of the kiln; a handle attached the control box and extending from an upper portion of the kiln; a platform base attached to the outer shell below the oven portion; a lid adapted to at least partially cover the oven space; and a hinge assembly having a first portion and a second portion, the first hinge portion being attached to the outer shell, the second hinge portion being attached to the lid, the lid being pivotally coupled to the outer shell by the hinge assembly, and when the lid is in a fully open position, the second hinge portion presses against the first hinge portion to limit a pivotal movement range of the lid so that the lid can rest in the fully open position with the lid extending upwards and tilted away from the kiln. 4. The portable kiln of claim 3, wherein the platform base has riser portions at the platform attachment points thereby providing an air gap between the platform base and a bottom of the oven portion. 5. The portable kiln of claim 3, wherein the platform base has a height dimension so that there is a spaced distance between the wheels and a floor when the kiln is sifting upright in an operational position on the floor. 6. The portable kiln of claim 3, wherein the platform base has a height dimension so tat there is a spaced distance between a bottom of the oven portion and a floor when the kiln is sitting upright in an operational position on the floor to allow air circulation beneath the oven portion and into the lower vent openings. 7. The portable kiln of claim 3, the outer shell having a generally C-shaped cross-section with tab portions disposed in engagement against the oven portion, wherein a distal end of each of the tab portions is generally parallel with the outer shell sidewall and the distal ends of the tab portions are separated from the outer shell sidewall by a spaced distance, and wherein the tab portions are integral parts of the outer shell.
