Jack,

If you can't find glass eye droppers - or what you need - any
where else try LabPro on Anvilwood Ct. in Sunnyvale.

http://www.lab-proinc.com/

They have just about every size and shape of glass ware you
might imagine. And although their main business is in
commercial quantities they also sell walk-in retail. Plan to
spend a 1/2 hour just browsing the 4 or 5 small aisles the
first time you go there. *G*

For small quantities I usually mix directly in the cup by
"counting the drops" in order to get the shade and thinning
I want. You can also mix in a bottle and transfer to the
cup.
