Amazing STRENGTH of

COLORTEX .......■

bricks

revealed by scientific tests



Result of compression strength tests, carried out at the Sydney Technical College on the 4th May, 1934, on the 100-ton testing machine, in the presence and under the supervision of the Departmental officials.


Six standard size Colortex Bricks (9in. x 4|in. x 3in.) were submitted for testing. The 9in. x 4|in. surfaces were faced with plaster-of-paris, and the load, commencing at 50 tons, was applied between these surfaces. The bricks were, in each case, subjected to a uniformly increasing pressure until the limit of the machine—100 tons—was reached.

Failure did not take place at this maximum load, thus revealing that the strength of the clay body of Wunderlich Colortex Bricks is in excess of 100 tons, the actual strength remaining undetermined.

A comparison of the strength of Colortex Bricks with the maximum recorded strength of other bricks, both special and common, is as follows:—

Colortex Bricks are available in standard sizes of 9in. x 4fin. x 3in. and 9in. x 4§in. x 2in„ and special shapes, with a variety of wire-cut crimped and rugfaced textures, and in a range of individual and blended colours, comprising Red, Brown, Yellow, Buff, Purple', Blue, etc., either matt surfaced or glazed. Select your requirements from exhibits on the Garden Display adjoining the Wunderlich Showroom.
