Gaffer no longer makes Eco clear ( It is an old product). The clear, Gaffer NZ has to offer is a high quality, brilliant clear. In Vals book : "Frit secrets" she made a list of her favourite clears. There are 4 on her list and Gaffer Clear(96 COE) is at the top. :)
I recomend you use Gaffer Clear with all your frit as it is 100% compatible with furnace frits.
Gaffer clear is not compatible with Effetre glass
Effetre(104COE) is dirty and bubbly and Lauscha clear which I really like is NOT COMPATIBLE with furnace frits.
The below photo is to demonstrate just how gorgeous and clear the Gaffer clear is.
