How to put two pieces of glass together
Isinglass glue can be used to repair a glass that has a broken stem. (Wine glass down on a glass table image by inacio pires from

Whether you are attempting to join two full pieces of glass, or repairing a glass item that has broken in two, it is important to have a glue that is strong but will dry clear, to prevent it from marring the look of the clear glass with unappealing colours. Creating your own glue using isinglass, spirits of wine (also known as ethanol) and water, you can create a fast-acting glue that will join invisibly, creating a like-new look.

  1. 1

    Put one part of spirits of wine into a pot or pan.

  2. 2

    Melt a piece of isinglass over the pot until two parts of molten isinglass has dripped into the spirits of wine.

  3. 3

    Add two parts of water into the pot.

  4. 4

    Place the pot on the stove on low heat.

  5. 5

    Remove the pot from the heat when the contents of the pot have melted and formed a transparent glue.

  6. 6

    Spread the glue onto the edges of the glass pieces where you wish to join them, using a clean brush.

  7. 7

    Press the two pieces of glass together and hold them firmly for five minutes until the glue sets. If the pieces of glass can be set down so that they stay together while the glue is drying, it is not necessary to hold the two pieces.
