Common questions
Why choose a vertical chamber over a horizontal Double Barrel oven?
A vertical chamber lets you suspend a blade from a rod hanger so it heats evenly along its full length without needing a long horizontal footprint in your shop — useful for longer blades or shops tight on bench space.
Can I still fire shorter blades horizontally?
Yes. The top hot zone includes a ceramic floor insert so shorter blades can be laid flat instead of hung, giving you both orientations in one oven.
What's the difference between the Vertical Base and a Vertical Pro?
The Base ships with dual solid-state relay control and independent zone thermocouples as standard. A SENTINEL Smart Fire or Touch Xpress controller upgrade is available if you want digital programmability instead of relay-based control.
Do I need the rod hanger system to use this oven?
No — it's an optional accessory. Without it, you can still use the top hot zone's ceramic floor insert to fire blades horizontally.
Is the warranty valid if I buy from Peach State Pottery?
Yes. Peach State Pottery is an authorized Paragon dealer, so your KM25 Vertical Base comes with Paragon's full one-year manufacturer's warranty. Register your oven within 30 days of delivery to activate coverage.
