I originally got these glass cloches - reproductions of C17th Dutch ones - because I wanted them for the garden but they got so many interested comments that I bought in enough to resell.
While I grow, make or commission most of our stock, we do sell commercially made vases, planters and the like so these fit into that category - no-one is going to think that I havea glassworks round the back of the tunnel.
As it is the first year that I have had them I couldn't answer any questions about how they stand up to the weather - well now I can. we have been down to -6 now and they are absolutely fine.
I assume that it is the shape that prevents frost damage - I imagine that it just slides off the sides. They don't keep the plants frost free but do make a couple of degrees of difference and keep the rain, snow and deer away. The parsley under the cloches is fine and green, the plants in the open are frosted to pulp.

The other question I got a lot of is - what can you do with them inside? I use them to keep the children's nature finds dust free and to elevate the pebbles, cones and nests into Victorian Naturalist territory.
But look at this page from
Elle Decoration - British artist Polly Morgan is putting dead robins and mini chandeliers into bell jars and charging from £4000 for the results. this one is called
A Thousand Years in Your Presence. Perhaps I should take Minou onto the staff and turn his kills into profit.
