My new DaniTrio Densho Raw Ebonite pen arrived today (flexi fine nib, matte finish), and it's everything I hoped it would be.

9 Having learned here that it's important to soak that
feed (edited 6/1/2006 to correct my ignorant use of the wrong word) in ink at the first filling, I had no trouble at all with getting great results immediately.
I have already pestered winedoc with a lot of questions, so I'd like to ask the group about the following:
1. When I got the pen, there was a little silicon grease visible on the pen body just where you turn it to open up the safety shut-off.

I wiped away the excess on the outside of the pen, but is it necessary to apply silicon grease there again from time to time? How about on the nib threads?
2. My office is only semi-airconditioned. In the summer it gets up into the low 90s in here. No direct sun, it's just very warm in the afternoon.

As long as the heat is in reason, I can handle it and the computers can handle it, but do I need to keep the DaniTrio in a cooler area of the house? Any likely harm from temperatures up to 95 F or so? (when it goes over 95 at my desk, I turn off the computers and take myself to a cooler area of the house). Never had any trouble with other pens, but I've never owned a pen made of raw ebonite before and don't know what the stuff will tolerate. My guess is that extreme cold might be a bigger problem than extreme heat, but someone here will know for sure.
3. I loaded the pen initially with Levenger Cobalt (mainly because I want to get rid of the bottle of it that I have -- the ink is darker than I like these days). When I change ink colors, I assume that I just rinse out the old ink from body and from nib
and feed (edited 6/1/2006, trying to get it right) by using cold tap water. Is that right? Will there be any problem if I get water on the raw ebonite?
Thanks for all the help I've received here!
