Which wax puck to use for Pressable Ceramics?	Use Wax Press or Wax Press Esthetic
Which investment material(s) do you recommend for your millable/castable wax?	Any high-strength investment will do (i.e. Microstar, Galaxy II, Ivoclar Press Vest Premium, Formula 1 (whip mix). In addition, these waxes have special rigidity for optimized machinability, so we recommend a two-stage burnout.
Two-stage Burnout Protocol	First of all, we highly recommend using a high-strength investment like the ones we’ve listed above simply because the particle size is smaller thus giving us a smoother and stronger situation to start. Invest and bench set for the appropriate time for specific investment Grind the top of investment to ensure a flat and stable surface and release of gases in burnout Enter furnace with first stage temperature set at 800* degrees and needs to rest at this temp for 25 minutes The second stage is heating up to a regular top temperature of 1550* where it will rest for 15-20 minutes on 100g ring and afterwards 35-45 minutes on 200g ring. This has universally worked with our millable wax’s and all investments that are appropriate for press.
Regarding the Wax Press and Wax Purity milling discs: Do you find if a different investment ratio is needed to get the best fit?	Most don’t have to change the ratio but we know that investment expansion has more to do with the ratio of special liquid/water than the material being burnt out so maybe adjust: a little more water and less special liquid. It will tighten things up.
