In the late 1980’s, a small glass scene developed in the great northwest. With less than a dozen borosilicate colors being pulled by Paul Trautman at Northstar color company, a small selection of torches, a handful of crude hand tools, and limited experience or knowledge of lamp working….. it blossomed into what we know it to be in today’s world. In the summer of 1988, Aim kilns released the first prototype showcasing a medium sized kiln with “doggy doors” giving artists access to a hot  kiln with guillotine style door while allowing their points or blow-tubes to stay cool to the touch. This model was named the 9169 GS and the first of it’s kind. While the prototype was rough around the edges, it was quickly tested and refined by the likes of guys like Bob Snodgrass, Bob Batrum, Jason Lee, Cameron Tower, Hugh, Ezra, Kameron Gray, and a short list of a few more. Without the culture they created, the process would have been delayed and far different. Aim kilns was proud to be a part of movement and over three decades later, we’ve reworked that classic staple and called it the P-91. 
The P-91 is a doublewide version of our 99LS or P-9, and allows for plenty of floor space for larger work or multiple artists to have enough room to work out of the same kiln. While it’s the same size as it’s predecessor, it’s gone through some serious changes including our newly engineered door style and some cosmetic changes giving it a fresh new look. Like many of the other models in our Professional Lamp Working Series, this model focuses on leading the pack in technicality, efficiency, dependability, durability, and value. 
This model was designed for bead making, pipe making, marbles, sculpture, and other various lamp working projects and has a recommended maximum working temperature of 1300F.
 
Features:
All new main door design incorporating five individual fully adjustable doors that offer a variety of versatility and options to make accessibility simple and highly functional.  
10 degree angle in the main chamber face that helps produce even heat throughout the interior chamber. This angled chamber cut also provides even wear and a tight door seal on every unit.
304 stainless steel used in the bead doors to handle temperature in high heat areas.
Fully adjustable pressure assisted door design allowing all doors to firmly stay open or in any position. *patent pending*
Our Profession Series kilns do NOT use any fiber board insulation in the lids, main doors, or bead doors as fiber board is an inadequate source of insulation and a major source of heat leakage and shrinkage when used as a sole insulator in annealing kilns.
Door gapping has been minimized to provide maximum efficiency, without sacrificing function.
Perfectly balanced main door and counterweight with new compact counterweight design allowing this model to fit into tighter spaces in a studio or workshop. Full adjustability to offer the perfect tension when opening/ closing main door.
Precise heating element placement in the chamber in combination with the 10 degree chamber angle help focus heat near the lower front portion of the floor to focus the heat where you need it and keep your work stable while accessing lower doors.
Extremely quick heat up time in this model, taking approximately 20-25 minutes to reach 1000F+ in most cases.
Well placed thermocouple providing extremely accurate temperature throughout the chamber.
Simple and precise electrical system making troubleshooting and offsite repairs much more simplified for customers.
Meticulous and unrivaled brick and mortar work in each and every lamp working kiln.
Detailed quality control process and 3-point inspection before product leaves our factory.
Each metal component or piece of hardware such as handles, hinges, arms, etc. is all custom designed and manufactured in house by Aim Manufacturing. No low quality off the shelf hardware parts used on our product which is one of the biggest differences that separates us from other manufacturers. 
New slotting design in the lower frame and wire pan areas to allow for more airflow to keep electronic components much cooler to extend their lifespan.
This model is pre- fabricated and set up for accessories such as rod rests, upgraded relays, modified hinges, and other modifications than can be added at time of purchase or easily added later. 
High temperature primer, metallic stove paints, and high quality powder coatings used exclusively.
Wood or high temperature anabolic handles used to keep exterior handles cool to the touch while giving the kiln a pleasing aesthetic exterior appearance. 
We offer a wide range of programmable digital controllers that were actually designed for lamp working to meet your individual needs.
