Questions about:

1. How many boards can I make with a bottle of conductive ink? I just want to know how long a bottle will last if I am making boards on a regular basis.

The amount of ink that you might expect to use will vary depending on your level of expertise, and the number and size of holes drilled in an "average board" the you make.  Generally speaking, if your average board is 8" X 10" ( 203mm X 254mm) with 1,000 holes (average diameter = 0.04", 1mm) you will consume about 2 or 3 grams of ink. When you first get started, you can expect to use quite a bit more.  But, as you master the technique, your ink consumption per board should fall dramatically. 

2. What is the shelf-life of the conductive ink? Do I need to refrigerate the ink between uses?

Our conductive ink has a shelf-life of 6 to 8 months at room temperature (20°C, 68°F).  If you store it in a refrigerator between uses (at night, when you go home) you can extend the lifetime to 1 year to 18 months.
