Cool, I need a titanium pen, not sure what for but I think I need one.

Out of curiosity, I looked up glass marking in Coyne "The laboratory Companion" a book I believe recommended by someone on DCHAS-l.  One option they suggest is using a titanium pen.  the text notes "...the markings are not easy to see (only 0.25 mm wide)."   I have not practical experience with this, but google does get numerous hits.  Here is one of the first ones (no endorsement, just high on the list):


Ti-Penª is the ideal glass signing tool for the lampworker, glass blower or glass jewelry maker. The Ti-Penª tool is different from most scribes because it writes by friction of the metal titanium point. Leaving behind a metal deposit in a silver color on the surface of glass, quartz, ceramics, or vitreous enamels. 

¥ Optimal for identification or designing on all types of glass work 
¥ Use for glass art, scientific lampworked glass, blown glass and cold worked glass 
¥ Offers fine line permanent marking 
¥ Use of this tool will not scratch, damage or weaken the glass 
¥ Will not obstruct the view of your detail 
¥ Smooth flowing fine lines can be obtained by moistening the surface 
¥ .25mm, .010" wide will withstand temperatures up to 1500¡ C
¥ Wider lines can be achieved by dulling the tip 
¥ Lines made by this tool may be electroplated to make circuits

The only sure way to do it is to go with borosilicate decals. These are water-slide on (like a temporary tattoo) that must then be baked on at about 1100 F.  Your issue will be that there's a setup charge for most of these, and there's usually a lead time.


Given your needs, I think the solution is to order page size sheets of numbers, letters, words, phrases etc. that you can cut out an apply to create the markings you need without running up a huge bill  for individual setup or having to wait for custom printing. You will, of course, need an oven/furnace capable of getting up to the required temperature and allowing the glass to cool back down slowly.


If you do a web search on "borosilicate decals" you'll find a bunch of suppliers. If you are looking for recommendations, almost any scientific glassblower (and many art glassblowers) can give you one.


One other purchase you may wish to make is a polariscope.  There's a writeup on glass stress and strain as well as polariscopes at our Scientific Glassblowing Learning Center page:

Our synthesis research lab has been discussing how to set up an inventory for all laboratory glassware beyond the quantity of each item.  I was curious if there was a way to track each piece. 


For example:

We have 4 100-mL single neck round bottoms.

Over the past 5 years we have bought 12 of these round bottoms.  8 have been cracked/broken/borrowed/etc.

Is there a way to keep track of each of the 12, so that we know which dates the 4 we currently have were purchased?  


Ideally the marking/labeling/serial number/etc. would:

- Not compromise the integrity of the glassware

- Be able to withstand the high temperatures of reactions (up to 290C)

- Be able to withstand a dishwasher cycle for cleaning

- Be resistant to Acetone/MeOH/Water


Goals of this inventory:

- Track age of glassware.

- Be able to list specific glassware used in reactions for continuity and sources of variables.

- Restrict certain pieces to fragrance synthesis only.
