A dissolvable glass projectile for a firearm is molded from dissolvable glass for the ammunitions and firearms industry. The dissolvable glass projectile may be molded into different sizes or geometry based on firearm and user preference. A mixture of chemicals components are heated and melted and then poured into a mold and is allowed to cool to a solid that can be handled.
A fibre structure formed from dissolvable glass fibres is provided, the dissolvable glass fibres being formed from one or more boron compounds and one or more alkali compounds. The dissolvable glass can be formed into filaments, rovings and staple fibres of varying composition, length and diameter dependent on functionality and purpose. A mixture of chemicals components are heated, melted and then drawn or extruded into dissolvable filaments, rovings and staple fibres for use in a fibre-reinforced composite part or as a preservative in the internal and surface treatment of solid wood and engineered composite panels. A water-soluble surface coating may be applied to adjust dissolution rate and facilitate binding into an air-laid nonwoven mat or incorporation into other matrices.

A method of forming a dissolvable part of amorphous borate includes: preparing a mixture comprising one or more boron compounds and one or more alkali compounds, at least one of the one or more boron compounds and the one or more alkali compounds being hydrous; heating the mixture to a melting temperature for a predetermined time to melt the mixture and release water from the mixture to form an anhydrous boron compound that is moldable, wherein the amount of alkali compound being selected to achieve an alkali oxide content of between about 10 to 25%; with the anhydrous boron compound at a molding temperature, molding the anhydrous boron compound in a mold; and cooling the anhydrous boron compound to form a solid..
Disclosed are compositions and processes for the preservation of porous materials, particularly porous fibrous material, such as wood, wood composites, other processed wood materials, paper, board, card, textiles, rope, cordage and leather Also for horticultural and agricultural application to plants or growing media prevent the growth and spread of fungal and other disease The compositions contain salts of one or more preservative metals and carboxylic acids having one or a plurality of hydroxyl groups rendered soluble by means of complex formation with boric acid or a water soluble salt thereof Application of the compositions of this invention to the porous organic material may be by any means used with conventional preservative solutions, for example soaking, spraying, brushing and vacuum or pressure application or other contact of the solution with the material to be treated.
