There are different types of products that make applying gold possible, hence different methods. Here, you can find the 4 main methods:
This technique is the oldest, dating back to Antiquity. As this technique is really hard, a prior training is needed. It involves applying many thin layers of various products before the gold-leaf can be used. This technique requires loose gold-leaf and uses ingredients such as glue made from rabbit skin, chalk and pigments. allowing the gilded surface to be polished at the end of the process, this technique gives a shiny finish.
This technique is easier than the water-based gilding technique. It is quite simple, requiring only an application of the milk with a brush and 15 to 30 minutes drying time and can be used either on loose or transfer gold-leaf. The finish is mat, and it is the cheapest option, though the results are not very hard-wearing. It is supposed to be used on item which are not daily handeled.
Mixtion or gold size
Suitable for both loose and transfer gold-leaf, this product takes 3 to 12 hours to dry. It fell into disrepute a few years ago, since it originally contained lead, which had to be removed, due to some cases of poisoning. The quality of the product was affected by this, but in recent years improvements have been made to the formula. The main advantage of this technique is that it allows the thinnest of layers to be applied under the gold, thus reducing the visibility of the glue (streaks, fingerprints). Thereby, a good result is easier to obtain. The finish obtained with this method is mat.
The newest technique involves a range of acryl-based products developed over the last 25 years. The finish result can be either mat or shiny. In this case, transfer gold must be used, as pressure is needed for the gold to adhere. The product (instacoll) is applied using a brush and left to dry for 30 to 40 minutes, leaving a time frame of approx. 2 hours for application. The main innovation (and advantage) of this method is that once the glue has dried, it can be activated using a special solution for up to a month after application. This allows the work to be carried out over a longer time period or in stages. As this technique involves products of quality, which offers flexiblity, this is the type of product that we provide you with.
