Beacon Hill Tower Roof (Step 6) Time will tell


The vinegar-salt mix was applied to the copper sheeting three days ago. It has dried thoroughly and the excess salt grains have been gently brushed off. It also got a blast with canned air. The copper is still a bit light, but if the test piece is an accurate guide, it will darken in the next several days.  I like the light green verdigris. It may darken a bit as well. For now I'll leave it alone. Eventually it will be dry brushed with various shades of craft paint, which will add to the age.

There are a couple of shiny copper spots where I think there may have been some glue that didn't get wiped off completely. They are not big and may darken on their own. Time will tell. 

It is not very clear in these photos, but the greenish verdigris is very near in value to the green of the shingles. When both are aged, I believe the copper roof and shingled roof areas will complement one another. 

Notice the tower roof unit resting on top of the tabs. There doesn't seem to be any hope of getting them to fit together. I believe the tabs will have to be cut off.  Haven't decided whether to add some bits of stripwood beneath the roof unit to keep it from sliding sideways or use magnets to hold it in place. I'm thinking having it remain removable may be useful down the road. 

The window unit is not glued. It needs to be caulked and painted and won't be installed until the aging process is completed.

I should probably continue working on the exterior of the house, but the staircase is calling out to me. I want to replace the flat bannisters that came with the house with round spindles for a more delicate, refined appearance. The redesigned units will still be removable. Which way will I turn? Stay tuned!

Beacon Hill Tower Roof (Step 5) Aging the Copper Panels


Before applying the aging mix, the copper was cleaned with a window cleaner containing ammonia. The half-and-half salt and white distilled vinegar mix was painted on the copper panels, taking care not to let is drip. The salt did not dissolve, as is evident in the photo. The salt grains will turn greenish blue to become the smoke-and-mirrors iteration of verdigris.  (Click photos for larger image.)


On line discussion indicates that humidity will enhance the aging process, to the tower roof has been tented, taking care not to let the plastic touch the copper areas.

Beacon Hill Tower Roof (Step 4) Installation of Copper Panels


The copper panels are glued in place. The photos show the sequence. The panels are paper backed. I dotted Aileen's Tacky Glue on the roof and pressed the panel in place with a pad of toweling, my fingers and a burnisher (seen at right).

The trickiest panel was the front, as it had to be gently worked behind the window sill.  I don't think I mentioned earlier that these adhesive-backed copper sheets are made for copper foil stained glass projects.They are a sturdy 1.25 mil thickness able to take the rubbing and pressing. If it were any thinner, I'm afraid there would be danger of tearing.

I placed the tower roof on the house to dry overnight. I'm planning to use the salt/vinegar aging mix and will tent it with a plastic bag, so I want to be sure the glue is dry or at least well set before subjecting it to the humidity. 

The shiny copper is a bold presence. The lighting was not the best for the photo, but you can get an idea of how it will work with the green shingles on the lower mansard roof bits when it takes on its own veil of green.
