Improved Method for Decorative 

 Glass Blowing 



A RECENT French patent describes 

 an improved method for hlowinji 

 glass in molds, so as to ol)tain ornaments 

 in relief upon the 

 ^.ll^facc of the oli- 

 ject. Aformha\-ing 

 the shape of the 

 bottle or vase has 

 the decoration put 

 (Ml in wax; then it 

 is co\ered by a 

 suitable molding 

 substance. By heat- 

 ing in the oven, the 

 wax runs out, leav- 

 ing the impression in the hardened mold. 

 Then the glass is blown into the hollow 

 mold, and the glass now takes the shape 

 of the cavities so as to stand out in relief. 

 The mold is carefully broken off the 

 glass, and the design appears in .sharp 

 relief.

 Bath Sponge 



HERE is a small economy for cleanli- 

 ness and comfort in the bath. As 

 is well known, large sponges soon break 

 up and become useless, and again they

<^ PIECES OF 

 SPONGE 



A bag made of Turkish toweling for in- 

 closing sponges to prevent tlitir clogging 



are subject to being clogged up by 

 impurities which are now recognized to 

 be due to microbe growth within the 



sponge. This is difficnlt to remedy in 

 the case of a large sponge. A new idea 

 is to assemble small pieces of sponge in 

 a bag so as to give about the same shape 

 as an original large sponge. The bag 

 can be made of Turkish toweling or 

 any suitable material. Thus all small 

 pieces of sponge can l)e utilized and can 

 be kept clean easily. 



A Draftsman's Inkstand Which 

 Will not Overturn 



A ROVING ink-bottle on a drafting- 

 table is a treacherous thing. To 

 keep it from turning over, take a piece 



The stand holds the ink-bottle in an 

 upright position and prevents it from tipping 



of tin or cardboard 3 in. wide and 5 in. 

 long, cut as shown in the drawing, and 

 bend up the tips. Pu.sh the bottle up 

 into this circular grip, and the tin tips 

 will hold it securely. If cardboard is 

 used, put a rubber band around the tips. 

 The bottle will be held securely and 

 cannot be accidcntallv o^•erturned. 



Renovating Nickel Plate with 

 Tinfoil and Solder 



WHEN touching up worn or rusted 

 nickel parts, first remove all rust 

 and dirt with a file or emery cloth. 

 Heat the surface and cover it with a 

 soldering flux. When suthciently hot, 

 rub a stick of .solder or some pieces of 

 tinfoil o\er it, until it is thoroughly 

 tinned. .After cooling, the surface may 

 be smoothed up with fine emery paper 

 and a piece of flaimd. 



This method may be used successfully 

 on motorcycle handlebars. It is hard 

 to tell the diflerence between the lead 

 and nickel, when the work is properly 

 done, and the lead will wear longer.
