Walter you forgot the smilies.Actually the blow torch thing is mainly for the surface plate or thin sections, not for heating batches.If you need to lower the viscosity put the mix container in a tub of hot water.If trying the torch you move quickly over the surface.BTW a paint stripping gun works also.To quote Walter "nice work Dave"
The rock batches naturally released air faster as the spaces are greator.A cheap air hammer may be a good vibrator.
Sandi, Quartz is a slavic word.
Bruno thanks for the link.I once wanted to say what we need is right under our noses.US silica and LV Lomas are good to deal with and offer bagged dry material.Some of the big guys only sell railcar loads.I think Lomas is also in Montreal and they have no problem with samples or one bag orders.

Larry,
You are right there is a LV Lomas in Dorval, thanks for the scoop

Martin,
Vacuum is also measured in KPa (KiloPascal) 1 KPa= .2952 in. Hg (inches of mercury)= .01 bars = .1450377 Psi = .0098692 atmospheres.

Igalla,

Are you sure of that? In Slovenian, the word for quartz sounds nothing like quartz....

Ah but Sandi,

Explain this one away.

Interesting... One learns all the time..

I really didn't know where it came from... Actually had a feeling it was German.

The Slovenian translation for quartz crystal is kremenchev kristal.
So you can see how I missed that one..

Thanks for the explanation.

Sandi
