Optional
Stain and Glaze firing with IPS e.max Ceram Glaze Spray
As an alternative to IPS e.max Ceram Glaze Paste and Powder, IPS e.max Ceram Glaze Spray can be used.
Please observe the following procedure:
– Prepare the IPS e.max restoration for Stain and Glaze firing as usual (surface texture, shape, etc.).
– Clean the restoration with ultrasound in a water bath and/or with a steam jet.
– If you wish to characterize the restoration using Essence and Shade material, apply a small portion of Glaze and Stain
Liquid on the surface before in order to promote wetting of the Stains materials.
– Hold the IPS e.max restoration with tweezers or secure it with a small amount of IPS Object Fix Putty or Flow on a firing
pin.
– The cavities of bridges can be filled with IPS Object Fix Putty or Flow in order to avoid application of the spray on the
inner aspects of the anchor crowns.
– Shake the spray can well immediately before use until the mixing ball in the container is moving freely (approximately
20 seconds).
– Observe a distance of 10 cm between the nozzle and the surface to be sprayed.
– Spray the restoration from all sides with short bursts to coat the (characterized) restoration with an even layer. Shake the
spray can well between individual bursts.
– Hold the spray can as upright as possible during spraying.
– Wait briefly until the glaze layer is dry and has assumed a whitish colour. If required, apply Glaze Spray again.
– If IPS e.max Ceram Glaze Spray accidentally reaches the inner aspects of the restoration, remove it with a dry brush.
– Place the IPS e.max restoration on a honey-combed firing tray for the (Stain and) Glaze firing and fire according to the
firing parameters for Stain and Glaze firing.
– Should renewed application of the spray be necessary after firing, spray the restoration in the same manner again.
Observe a distance of 10 cm when applying the IPS e.max Ceram Glaze Spray. Spray IPS e.max Ceram Glaze Spray with short bursts directly on the unfired Essence
materials and/or Shades from different directions.
Shake the spray can well between
individual bursts. Restoration with evenly applied IPS e.max Ceram Glaze Spray before Stain and Glaze firing.
