The whole support frame is made from heavy duty welded parts that are easily assembled on site so that the system can be easily broken down for inexpensive common carrier shipping. (It is a two
The welded angle-iron stand is separate but attached to the case. It includes leveling bolts and holes for anchoring the kiln to the floor. The angle-iron frame is covered with a layer of aluminized steel which the bottom of the kiln sits on.
A proprietary brick coating is applied to all interior surfaces of the kiln. This is put on before the element holders are inserted. This coating penetrates the firebrick and fuses the surface on a microscopic level which helps prevent dusting and crumbling of the fragile firebrick.
Solid ceramic peephole plugs with full 1” diameter. Six total: one per section.
Three control zones with three separate thermocouples. More about zone control.
8 Ga Type K Exposed Thermocouple in Mullite Protection Tube (4.5" long /114mm)
Mounted on panel
Floor-mount Plug-in.
Control box cover is hinged for easy access to inside of control box. DynaTrol is in a removable handheld box. Entire control box is removable.


Durability, Repairability, Better Heat Transfer. The smooth, hard surface of the inside ceramic channel allows the elements to expand and contract freely. No pins! The dense ceramic holders extend element life because they do not insulate the hot elements from the kiln interior.
Arched sides on DaVinci kilns are very strong and promote good air circulation
Mullite protection tubes extend thermocouple life and keep kiln clean. The mullite protection tube keeps the metal oxides of the thermocouple tip from dropping off and contaminating your work.
Industrial grade ceramic terminal blocks make changing elements easy.
Special brick coating hardens and seals brick for durability and cleaner operation.
Thick 8 gauge thermocouples last a long time. Special Limit of Error to ANSI MC96.1 specifications is used.
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.


Zone control gives you the utmost in controllable temperature uniformity. The DynaTrol separately measures temperatures in the bottom, middle and top of the kiln and automatically adjusts the heat output of three zones during the entire firing.
DynaTrol with 4 Easy-Fire programs (Slow Bisque, Fast Bisque, Slow Glaze, Fast Glaze), 6 custom programs, PreHeat, Delay, Program, Segment Review, and Diagnostics. Zone control included on most kilns.
K23 firebrick combines good insulation with strength

Ease of Use

Load your DaVinci kiln from all four sides. Available on T3400 and X3200 Series.
Solid large non-tapered peepholes allow a wider view into the kiln.


The combined experience at L&L Kilns in kilns, ceramics, electrical engineering and process engineering is unsurpassed. We work as a team to help you get you answers and help.


DaVinci Panels are wired to industrial standards with good clean wire layout.


The combination of 1/2" diameter element coils, the doubled surface area of the Quad element design, and superior heat transfer of L&L's patented ceramic element holders, make this the best element system in the world today. 

APM elements increase element life in difficult applications


Type S Platinum Thermocouples are recommended for high fire applications. NOTE: Price of upgrade is per each thermocouple. 

Pyrocil thermocouples are sensitive but limited to about 2200°F but offer greater sensitivity to temperature change and so may be appropriate in applications below 2200°F that require sensitivity. NOTE: Price of upgrade is per each thermocouple. 


The Vent Control allows you to automatically control the operation of the Vent-Sure kiln vent with one of the outputs from the DynaTrol (or Genesis). 

The multi-mounting bracket for the Vent-Sure Vent allows you mount the vent motor in several different positions.

The L&L Vent-Sure Kiln Vent is the most powerful downdraft kiln vent on the market today. That means you have more flexibility in the installation.

These safety gloves are perfect for handling hot work when unloading a kiln.


The new Genesis control from Bartlett includes a touch screen interface and WIFI connectivity added to the proven software of the DynaTrol. 

Solid State Relays are quiet and result in longer element life.

Electronic High Limit Back Up Control acts as an upper limit back up to the main control.

Control, monitor and record data for up to 10 kilns from your computer for a one-time price.

The Eurotherm 2604 is an indutrial-grade PID control with two or three zone cabability built in.
