Oh wise women of Mumsnet, I have made a right hash of this!
Tall hurricane lamp - long, but I can reach the bottom.
It is straight, tube shaped until you get to the bottom, where it goes in sharply and out again to make a wide foot. Like a crevice going right around.
I put sand in the bottom, put a tallish wide candle in, and tastefully adorned the inside with seashells ( You may snort) then placed it in the conservatory.
My conservatory is south facing, and the never lit candle melted into the sand.
I now have a sand cement wedged all around the crevice.
I have managed to remove the cement from above this crevice, but cannot get in to the crevice to remove it.
It is a horrible colour, so don't want to leave and just add more sand.
The glass is thin, and I love the lamp, so am cautious.
Warm water did not work.
Any ideas gratefully received!
