Asperitas offers its kiln for bisque and glaze firing, for high and low temperature, up to 1250°C.

The kiln is a Rohde Ecotop 60, with internal measures of 45 cm in height and 40 cm in diameter; therefore this is the maximum size of the piece that can be fired, larger pieces will not fit.

Each kiln shelf is circular, with a diameter of 35cm.

Firing temperatures:

  • Bisque: 950°C
  • Low temperature glaze: 1020°C – 1080°C
  • High temperature glaze: 1250°C

Note: These are the temperatures I would normally use for my firings, the temperature and cycle can be adjusted upon customer request.

  • Firing of individual shelves will be carried out within a period of time between 1 and 6 weeks, depending on the availability of the studio, the entire kiln takes place within 1 – 2 weeks.
  • The glazed pieces MUST have the base / support surface completely cleaned of any glaze residue, with an edge of at least 3 mm starting from the base of the piece, to avoid the glaze dripping onto the shelves. If the pieces are not cleaned properly, Asperitas reserves the right to apply a surcharge of €35 per hour for the labour of properly cleaning the pieces.
  • You must inform the studio in advance if any pieces are covered entirely in glaze and require the use of tripods to fire.
  • It is necessary to inform the studio about the firing data of the clay and glazes used, to avoid damaging the pieces and/or the kiln.
  • Asperitas declines all responsibility for damaged pieces and no refunds will be made if the pieces do not turn out as expected (cracks, bubbles, color changes, runny glaze).
  • If the pieces cause substantial damage to the kiln and/or the shelves (for example due to explosions or dripping of glaze) the customer commits to reimburse the studio for a sum equal to the extent of the damage.
  • The kiln is used only and exclusively by Asperitas employees, the customer will not be involved in the loading or unloading process of the oven.
