I turned out the master in Jelutong. It is rubber tree wood and is very close grained and is a soft wood. It is used mainly for carving. I finish it with sanding sealer and then a couple of coats of polyurethane varnish covering it completely. I started with a block made up of 2x 12.5 inch squares a...

Hi Tom

I think that this may solve your problem with plugs. When adding to or repairing porcelain crown and bridge work I make masks (plugs) to protect the bridge and then I can weld new or extra pieces to it without damaging the bridge The secret is to use a 50/50 mix of Plaster of Paris and fine pumice O...

Hi Dragon Glass slumping moulds are made here in South Africa. They were designed to have wall thicknesses of approx 5mm and also to have the bottom of the mould suspended off the shelf in the kiln. In the outer wall of the mould there are two half moons cut out of the walls to act as handles and to...

Hi I have been trying Vidtriate's products for a while now and find them very good. They have a range of low fusing paints for glassware at 500 to 600C ( 932 to 1112F) see http://www.vidriarte.com/colores-fritas/pint-baja.htm Haven't tried these yet but if they are like their products for float then...

Hi all
I can source calcium silicate boards here in South Africa.
I would like to know if this product would be suitable for cutting drop rings and making moulds. It has a rating of 1000C and comes in sheets of 1.2 metres x 50cm Would I have to use kiln wash with this type of board?
Thanks
Ian

Hi Lynne
Yes I have one in my Dental Lab and I use glass beads, aluminium oxide in 110 250 micron without any problem aith a 100litre compressor I think thats about 25 gallon, bought from a hardware store

Sorry people
I haven't made myself clear I don't want to convert 100C to F. I want to convert say 200F per hour to C per hour which is a different calc which I have lost
Thanks for all your help
Ian

Could it be cast in a centrifuge with oxides poured onto the melt in the crucible which on casting would swirl oxides onto surface of finished cast

( talk about throwing the cat amongst the pigeons)

Thanks Brock
But I am asking about temp RATE conversion as opposed to straight F to C conversion.

Our Educational system in South Africa is as good as yours in America don't you think

Does anybody know how to convert temp rates to Celsius so that us poor colomials in deepest darkest Africa can follow all the firing schedules that are posted
Thanks

Hi Russ I don't see a problem with painting on glass if it gives the desired result. It's the end result that counts. I can't remember where I saw it but it was a sand carved picture of swans and there where gold tinted tips on the wings and the head of the swans Without the gold highlights it would...

Glass beads were actually developed for blasting dentures to get rid of plaster of paris which is used in molds to cure dentures. Dentures are made from acrylic and the glass beads are soft enough not to damage the acrylic teeth. If you need a sandblasting unit for small jobs such as blasting patter...
