<p><span style="font-family: Courier New;">Hello and greetings! I enjoy this board immensely, having just discovered
it.<br></span></p><p><span style="font-family: Courier New;">I have become interested in chemistry after a long absence
from the field. I've been refinishing some old wood pieces, and have been playing with coatings.<br>
</span></p><p><span style="font-family: Courier New;">The self-polymerizing wood oils, like tung and linseed, are very
interesting. They photopolymerize spontaneously (or with commercial accelerants.) Oily rags with polyunsaturated linseed can heat
up to ignition by the exothermic processes of polymerization.<br></span></p>
<p><span style="font-family: Courier New;">I have become interested in using sulfur to "rubberize" linseed after it has
been applied, to make a hard coating. Sulfur, amazingly, can be heated to liquid using a steam iron, right on the wood -
odorlessly! The Pennsylvianians used to make furniture with inlaid liquid sulfur. You would think it would stink to the
dickens.<br></span></p><p><span style="font-family: Courier New;">I'm interested in making "home-made
linoleum," which was originally linseed oil and cork shreds, vulcanized.<br></span></p><p><span
style="font-family: Courier New;">Anyone got some ideas?</span></p>The WiZard is In - 31-5-2010 at 09:02
