Hi,
We have just received a delivery from the USA and this includes Northstar frit and rod. We were out of stock of a lot of rod colours so we have restocked all of them and added 11 new Fine frits to the range, apart from clear we have never stocked boro frit before so this is a new toy for us to play with.
More details are on http://www.tuffnellglass.com/contents/en-uk/d316_Northstar_Coloured_Borosilicate_.html (http://www.tuffnellglass.com/contents/en-uk/d316_Northstar_Coloured_Borosilicate_.html)
Best wishes ,
