Did you know the speckle glass can be reused as lovely vessels for burning tea lights.
When you have burnt your gorgeous candle and finished with it, pop the vessel in oven on low heat around 60 when the last bits of wax melted wipe out with a bit of kitchen roll and then wash in soapy water .. don't worry about the wax as soya wax is 100% biodegradable
Then pop your tealight in vessel! Perfect....
