Even since we saw some glass fusing with plant material I have wanted to have a go.
Time, the garden, and the bees have conspired to thwart our attempts to find the couple of hours needed to try it out, but, with the nasty weather over the last few days, we decided that today was the day.
A little online research brought up about 4 different techniques to cope with the basic problem that, at 800 degrees, the temperature required to melt the glass, all plant material will have turned to carbon.
This picture shows the 9 different test pieces, all slightly different, to determine the process that works best for us for different leaf types.
Come back in a couple of days to see the results.
In the meantime keep your fingers crossed.
