Up until 1998, Pyrex was also made from borosilicate glass, but is now made with soda-lime glass, a glass that is already used in the manufacture of many food and beverage products, as well as for windows. ❋ Unknown (2009)
It may be based on boro-silicate or soda-lime glass with other metallic oxides added to improve its thermal and optical properties. ❋ Unknown (2005)
In the case of modern soda-lime glass, a quick cooling will produce a glass transition at about 550° C. ❋ Unknown (2005)
Roman glassware provides some of the best available evidence that types of soda-lime glass are not fluid, even after nearly 2000 years. ❋ Unknown (2005)
Usually there were other impurities which made it softer than modern soda-lime glass. ❋ Unknown (2005)
I did think of killing it, and, on the whole, I rather wish that I had at any rate attempted slaughter, -- there were dozens of things, lying ready to my hand, any one of which would have severely tried its constitution; -- but, on the spur of the moment, the only method of taking it alive which occurred to me, was to pop over it a big tin canister which had contained soda-lime. ❋ Richard Marsh (N/A)
~ Methane is prepared in the laboratory by heating sodium or calcium acetate with soda-lime. ❋ William McPherson (N/A)
Equal weights of fused sodium acetate and soda-lime are thoroughly dried, then mixed and placed in a good-sized, hard-glass test tube fitted with a one-holed stopper and delivery tube. ❋ William McPherson (N/A)
The importance of having the soda-lime or potash-lime somewhat moist, to secure the highest efficiency for the absorption of the carbon dioxide, makes it necessary to absorb the moisture taken up by the dry air in passing through the potash-lime can. ❋ Francis Gano Benedict (1913)
The method of determining the water-vapor and carbon dioxide in the residual air is extremely simple, in that a definite volume of air is caused to pass over sulphuric acid and soda-lime contained in U-tubes. ❋ Francis Gano Benedict (1913)
However, the important point to be noted is that whatever fluctuations in composition of the residual air were noted by the soda-lime method, similar fluctuations of a corresponding size were recorded by the volumetric analysis with the Sondén apparatus. ❋ Francis Gano Benedict (1913)
All experiments with potassium hydroxide in the form of sticks or in solution failed to give the desired results and the use of soda-lime has supplemented all other forms of carbon dioxide absorption. ❋ Francis Gano Benedict (1913)
Potash-lime has not been found practicable for the U-tubes because one can not, as in the case of soda-lime, see the whitening of the reagent where the carbon dioxide is absorbed. ❋ Francis Gano Benedict (1913)
The results of the analysis were expressed on the basis of moist air in volume per cents rather than by weight, as is done with the soda-lime method. ❋ Francis Gano Benedict (1913)
More recently we have been using potash-lime, substituting caustic potash for caustic soda in the formula, and the results thus obtained are, if anything, more satisfactory than with the soda-lime. ❋ Francis Gano Benedict (1913)
Believing that the method of analysis as outlined above should be controlled as far as possible by other independent methods, we were able to compare the carbon dioxide as determined by the soda-lime method with that obtained by the extremely accurate method used by Sondén and ❋ Francis Gano Benedict (1913)
Instead of using small cylinders containing 10 cubic feet and attaching thereto purifying devices in the shape of soda-lime ❋ Francis Gano Benedict (1913)
The soda-lime borate ulexite occurs as irregular balls, rough on the outside, but found on breaking to consist entirely of white, silky, radiating annular crystals. ❋ Unknown (1903)
The first weighed tube contains pumice and cotton wool, moistened with water; the second tube contains soda-lime as well as (in the upper half of the second limb) fused calcium chloride between plugs of wool; the third tube is filled half with soda-lime and half with fused calcium chloride. ❋ Cornelius Beringer (1886)
The sixth also contains calcium chloride and soda-lime; its object is to prevent the access of moisture and carbonic acid to the weighed tube from this direction; it is connected with an aspirator. ❋ Cornelius Beringer (1886)
