Glass Blowing Made More Affordable

Let’s face it, building, running and maintaining a crucible kiln can be expensive. The GM818CR offers an affordable alternative to traditional melters.



Internationally recognized Borosilicate guru Marcel Braun has been using these kilns for quite some time now. He works mainly on the torch but often incorporates gathered glass in his larger pieces.

An electric melter allows you to easily and cost effectively heat up the glass you need for a week or even a weekend and then anneal the crucible when you are finished. Be sure to watch the video with him and legendary Artist Robert Mickelsen, collaborating on a truly masterful piece.

Ryan Staub

Seattle Glass Artist Ryan Staub loves his. Here are the reasons he gave us:

  • Best one on the market.
  • Gathering port is just right, not so small it’s hard to gather out of, not so big it dumps all the heat when you gather.
  • Great for a small home or garage studio.
  • Good addition to a full sized glassblowing studio as an affordable color pot.
  • Easy to ramp down slowly, minimizing risk to your crucible.
  • Small and easy to store when not in use.
  • Easily programmable controller with indefinite hold.
  • Easy to install.
  • Low energy use, high efficiency. (Average cost is $15/day)

KilnMaster Controller

Sophisticated, Yet Easy to Use

  • Write your own firing programs with up to 8 Segments using Ramp and Hold. Now you can store up to 12 programs.
  • Built in Diagnostics give you or our technicians the ability to diagnose kiln problems with just a few button presses.
  • The Alarm feature allows you to set a temperature alarm that will notify you when the kiln is at peak temperature.
  • Adjust temperatures or hold times while the kiln is firing using Add Time or Add Temp or simply press Anneal Now and begin annealing it.
  • Use the Delay Start feature to fire the kiln when it is convenient for you to be there when the kiln reaches temperature.
  • Add KilnLink and monitor your kiln from your smart phone, or even more important, receive a text messages if it unexpectedly starts dropping in temperature.
  • The Infinite Hold Feature ensures the program will not end until you press stop.

Kiln Elements split

Solid State Relays

Solid State Relays are just what the name implies…they are SOLID. When you have a $200 crucible filled with $1000 worth of glass, the last thing you want in the world is to have a relay go out. Over our 50 years we have tested a lot of relays and solid state relays when engineered with a properly sized heat sink are some of the best.

Kiln Elements split

Balanced APM Elements

The GM818-3CR comes standard with APM elements. For people who are using material that does not out-gas too many caustic fumes (like batch or many colors) these elements should give you significantly longer life. They have a different cell structure from standard A-1 element wire which is more dimensionally stable at higher temperatures.


Type S Thermocouple

Most all of the kilns that leave are factory are equipped with a Type K thermocouple. Type K thermocouples are accurate and inexpensive. The downside to Type K thermocouples is that they wear out, and they wear out faster when exposed to extreme conditions. Type S thermocouples can virtually last forever. The reason for this is that they are made of platinum which does not degrade under most atmospheres and has an extremely high melting point. This leads us to one of their downsides, they are expensive…BECAUSE THEY ARE MADE OF PLATINUM!!!

They are mostly used in scientific settings where they are constantly exposed to harsh environments like that of a crucible kiln. Because it is made of very expensive Platinum, the wire used to construct the thermocouple is very, very thin. On top of this, it is housed in a fragile high alumina cover. If you hit it with a crucible, it’s game over, so be careful.


Current Sensing Technology

Skutt is one of the few brands that installs a Current Sensor in every KilnMaster Kiln. This allows you to read the Amperage of each section of the kiln as well as the Voltage and Voltage Under Load.

Now with the touch of a few buttons you can give those readings over the phone to your kiln repair technician so they can troubleshoot the problem and make sure they have the correct parts when they come out for the repair. This Saves Time and Money.

Prior to the use of these current sensors someone would have to come to your house and test the amperage and voltage inside the control box with live wires exposed. This system is Much Safer.


The Mantis Lid System

The Mantis Door System was designed for ease of use and ease of maintenance. The top hat door rocks back on an arc, keeping the hot face of the lid facing down so it does not radiate heat back at you while you are dipping. It has a wood handle that stays cool so you will not burn yourself. The main lid is hinged seperately and is cut with an 8″ access hole. To load or remove a crucible simply release a chain that allows the Mantis frame to move out of the way and open the lid.

When glass is molten it is conductive. When the top hat is opened, a shut-off switch is activated so you will not shock yourself while dipping.

Sectional Design

Sectional Design

Sectional Design is a good idea on so many levels.


Imagine trying to move a kiln into the basement or through a narrow door without being able to break it down into sections.

No more standing on your head in the kiln to replace those bottom elements or removing every brick in the kiln to get to the one you want to replace. Just remove the control box, unhook the buckles and place the section you want to work on on a table.

We hope nothing really bad happens to your kiln … but … if it does, isn’t nice to know you can replace one bad section instead of the whole kiln?
