This refillable pen is another item made at VortexGlassWorks by Kenny Talamas in Oregon United States showing the versatility of this studio. The reason for the use of borosilicate glass (Pyrex) is that it is impact and scratch resistant so it is less likely to break when being used.
This green tree frog with orange feet on a cork screw shaped vine branch with a leaf in dichroic borosilicate (Pyrex) glass is very lifelike. Made by Kenny Talamas at VortexGlassWorks in Oregon United States which seems to be creating a range of wonderful sculptural works.
