It is probably varnish. That was what gave brad a problem, with the varnish bubbling up, although no one else has reported any problems. Varnish isn't necessarily a negative. I have one French Jobey and an Italian Giani, both with a coat of shiny varnish, and instead of being sealed up, they seem to breathe and smoke just fine. They do fine with any blend, and seem to enhance aromatics somewhat, and do fine with non-aromatics (most of what I smoke) as well. tuold, that's a fine lithe Dublin, a real French take on the shape. I kept shopping these pipes, but finally ordered a Genod bent egg shape instead, as a real early Francophile shape. It cost a little more, but seemed to answer the "need."
