Supplying Materials to Glass Makers since 1987

Specialising in the supply of metal oxides and raw materials for machine made and hand made glass - Glassworks Services was set up by Bill Simpson after 35 years as a glassmaker and as the technical director of a manufacturer of raw materials.

From 2000, we diversified into supplying Kugler Colors for hot glass studios, base glass nuggets and batches, polishing powders and glass makers tools.

Due to being a major stockist of  metal oxides,our connections in the ceramics industry led the family, in 2006, to buy out one of our glaze making customers and start to supply ceramic studios, artists, colleges and schools with a wide range of products -  go to

 CTM Potters Supplies for more info.  

From 100 gm to 5 tonne lots we can supply a wide range of metal oxides : Antimony, Chrome, Cobalt, Copper, Manganese, Selenium, Zinc etc

Metal Oxides

To support the remaining studios that melt their own glass we do usually stock Sand, Limestone, Soda Ash, Barium, Zinc Oxide, Antimony, Pot Nitrate etc

Glass Making Materials

If there is a material you need, and we do not stock it for glass making, there is a good chance our sister company CTM Potters Supplies has it - so please ask us.

Ceramic Making Materials

Jim and Liz have made glass makers tools for friends since the late 80’s but, as Jim says, beer stopped being legal tender in 1994 when he went to the Glass Art Society trade fair and started selling “tools that feel right in your hand and that you feel right owning - tools that do exactly what you want, every time you pick them up”. We stock the most popular ones and usually order from Jim and Liz about once every three weeks.

Produced in Neugablonz, Bavaria by the Friedrich family since 1985, the Kugler coloured glasses for hot glass blowers are respected throughout the world as the standard by which others work to.  From our store in Doncaster you can choose from the vast range of over 160 blowing colours which we stock in rod, powder, and the most popular frit sizes. Any we do not have we  can bring in for you on our weekly order.    

We stock three plasters and various sizes of molochite, quartz and silicas, corderite and firebrick grogs.
