These are not the cheapest tools - but they “feel right in your hand and you feel right about owning them. Tools that do exactly what you want, every time you pick them up”  

Stocked in Doncaster are approx 100 of the Kugler’s 160+  blowing / casing colours in the 3 cm thick rods, powders and most of the seven grit sizes.

Kugler Colors have been made by the Friedrich family since 1985, and at their environmentally friendly factory in Neugablonz since 1995.

We order weekly from Kugler so if there is a colour or size that you need, that we do not have, it should only be a week or so - or choose from one of the many other colours.

We do not usually stock K3, K4 and K5 so there may be additional delivery charges for those.

Nuggets Safety etc Material

Our main glass nuggets for blowing is produced to Kugler’s recipe- specifically designed to work with Kugler and Gaffer coloured blowing glasses (not suitable for Reichenbach as they usually have a lot lower COE - though some people do). It comes in 25 kg boxes and we are told by several customers that it has very good and forgiving working properties for hand glass working, similar to using 24% lead crystal cullet.

We have some Philips non-lead batch clear glass pellets in stock, and various green glass pellets in stock going very very cheap - please ask.

We may have some clearance stock of lead and no lead batch for non-important melting at extremely low prices.
