PotterycraftsTopworker 120 Top Loading Kiln

A 120-litre professional top-loading kiln for studios, schools, and colleges working at medium to large scale. More capacity than the Topworker 80 with the same Stoke-on-Trent build quality, stainless frame durability, and Potterycrafts' trusted engineering.

  • 120-litre chamber: Substantial professional capacity — fire large batches or tall pieces at a scale that reduces the number of firings you need to run.
  • 40A dedicated supply: Higher power for a larger chamber — requires a hardwired supply by a qualified electrician.
  • Stainless steel frame: Built for the demands of regular professional use — durable, corrosion-resistant, long-lasting.
  • Type R thermocouple: Consistent, accurate temperature control throughout the chamber at every firing cycle.
  • Gas strut lid: Smooth, assisted lid for comfortable loading access at this chamber size.

Potterycrafts Topworker 120L. Dedicated 40A supply required. Optional CERA-10+ controller. Free UK delivery.

Requires a dedicated 40A single-phase supply. Call 01206 648025 before ordering.

More Capacity, Same Build Standard

The Topworker 120 is the step up from the 80 — the same professional build quality and construction philosophy, with 50% more chamber capacity. At 120 litres, a single firing can handle a full week's studio output for a productive maker, a substantial school programme load, or pieces at a scale that couldn't comfortably fit in an 80-litre kiln.

The internal chamber dimensions of 46cm wide × 69cm high × 89cm deep give you a tall, generous space — particularly useful for studios working with taller sculptural pieces or large thrown forms that need headroom. The 108mm Ultralite granular floor insulation maintains even heat at the base of the chamber even when the load is full.

Requires a dedicated 40A single-phase hardwired supply by a qualified electrician, or 3-phase at 15A per phase on request at point of order. Call us before ordering to confirm your studio's electrical setup.

The Topworker 120 Is Right For You If

  • You need more than 80 litres and want top-loading practicality
  • You fire at a scale where 80 litres is too small for a single batch
  • You run a school or college with a significant ceramics output
  • You want Potterycrafts build quality at 120 litres
  • You're considering front-loading but prefer top-loading access

What the Topworker 120 Delivers

120-Litre Chamber

50% more capacity than the Topworker 80 — a meaningful difference when you're firing regularly. The taller internal height (69cm) gives you room for pieces that wouldn't fit in a shorter chamber, and the 46cm width accommodates generous shelf layouts. Three or more shelf levels are practical at this height with the right prop configuration.

Built-In Safety Features

Dual contactors and over-temperature monitoring (when used with Potterycrafts controllers), captive interlock safety switch, side vent with chimney, lid vent holes, Type R thermocouple, and full ROHS and WEEE compliance. The Topworker's safety specification is consistent with Potterycrafts' professional studio kilns — not a simplified version for the top-loading format.

CERA-10+ Control Options

Compatible with the CERA-10+ controller (32 programmes × 32 segments each — ramp, target temperature, and hold) and the CERA-10+ WiFi, which adds remote control via PC, tablet, or smartphone using the GATEway app. Controllers are optional at the point of order — the kiln can be supplied without one and upgraded later.

3-phase supply available on request at point of order (15A per phase). If your studio has 3-phase available, this can reduce your individual circuit requirements and may suit better than a single 40A phase. Ask when ordering.
