Another checking example in a wenge top.
If the cracking is enough to bother you visually there are a couple of ways to “fix” the issue. Again, bringing the moisture level in the air back up to around 50% relative humidity will allow the wood to self correct in most cases. If that doesn’t work the easiest approach to take is filling the check with a wax furniture crayon. It’s easy to do and you will need only a credit card or other non metal scraper, a lighter and a soft cloth. You’ll find instructions on the package, but basically you’ll be warming the wax with a lighter and filling in the crack with a hard wax. Then, using the credit card, you’ll scrape back the excess and polish it with the cloth. Just match the crayon color up as closely as you can with the top and you’ll have no problem.
It won’t be long until time for open windows and spring sunshine. Like icy sidewalks and frosty windshields, this too shall pass.
