This is a very collectable piece of British Art Glass. It was made by Jim Dyer in the 1970s. The Liskeard Glass company was founded in 1970 by John Randle.
This shallow bowl is from the "knobbly" range and it is very similar in many respects to the knobbly range that was designed by Jim's brother, Harry, at Whitefriars.
The Liskeard range is easily identified by the distinctive LG logo on the base, as photographed.
This is a nice sculptural vase- with an emerald green center and with a knobbly outer casing of clear glass.
It is 5 1/2 inches in height and has a diameter of 4 inches. It is certainly a heavy piece - and weighs in at 1.6 kg unpacked.
