Tips for pressing flowers using a microwave There are a few references to speeding up the process of drying flowers using ceramic tiles (apparently ones for this purpose) and a microwave, but not many of the videos and guides are very specific about the length of time and power of the microwave that works best. 

Obviously this also depends on the type of flowers, but I am wondering if there are some tips that are useful while someone is trying to experiment and work out the best settings and parameters to set for doing something like this.
The following might be suboptimal, but it worked several times for me (and is purely empirical):    


Set the microwave at minimum power.  
Put the flower in a folded paper towel which you place in a tupperware.   
Put the tupperware a few seconds in the microwave.   
Open the tupperware, change the paper towel and dry the vapor in the tupperware.  
Restart at step 3 until you are satisfied.  


Of course, the number of seconds depends a lot on the type of flower. Typically, I start with 5-10 seconds and then decrease the amount of time. I never did it for flowers with petals, but I guess that you'll have to reduce the time in this case. Note that keeping small times allows a better control on your experiment.
I should admit that I never could get it as dry as after a long natural process, but you can definitely boost it with this technique.
