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.
In 2006 our connections in the ceramics industry led the family to set up Simba Materials Limited 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. Since summer of 2023 Simba Materials Limited now runs both the sales to the Handmade Glass craft sector and Ceramic craft sector.
From 100 gm to 5 tonne lots we can supply a wide range of metal oxides : Antimony, Chrome, Cobalt, Copper, Manganese, Selenium, Zinc etc
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
If there is a material you need, and we do not stock it for glass making, there is a good chance our sister business CTM Potters Supplies has it - so please ask us.
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.
