Rebecca,
What is "capillary action"?
Also, my foiled pieces are never exact and completely w/o space against another piece. There is always some space between pieces, aren't there?
As least there is on my panels.
thanks.
Here is the definition from Wikipedia:
"Capillary action, capillarity, capillary motion, or wicking is the ability of a substance to draw another substance into it. The standard reference is to a tube in plants but can be seen readily with porous paper. It occurs when the adhesive intermolecular forces between the liquid and a substance are stronger than the cohesive intermolecular forces inside the liquid. The effect causes a concave meniscus to form where the substance is touching a vertical surface. The same effect is what causes porous materials such as sponges to soak up liquids."
Some people claim that "capillary action" will pull the solder into the space between the glass pieces no matter how small that space is. I don't buy it. I make sure there is room for a pin EVERYWHERE. Is it overkill? Maybe. But that's the way I do it.
Rebecca
