Introducing blackjack - a leather tankard. The first fragments of leather containers come from Scotland, 6th century. Blackjack became popular in England during 13th century mainly with sailors. The reason is practical. A leather tankard does not break during storms and it is lighter than pottery. Sailors were allowed to take only a bag of stated size on board plus there was a weight limit. A large number of such tankards and other leather objects were well documented on the board of the wreck of a sunken ship called Mary Rose. These blackjacks, like everything else in my workshop, are handmade including sewing. A blackjack goes through a hot wax and resin bath.
Its capacity is 0.5-0.6 l.
The tankard is fully functional. It is suitable for water and beer (tested). It is not suitable for hot, acid or aggressive liquids or liquids with high contents of alcohol. Do not expose it to high temperatures or direct sun (might cause softening, deformation or even leaking).
Made of 5 mm water buffalo leather
Special treatment for flasks and blackjacks:
Those products are made with a hundred years old manufacturing method. The product is boiled in a mixture of beeswax and resin (resin used in the food industry), the product is fully functional and watertight. Thanks to legal standards, this is a decorative and also fully functional item. Put only cold liquids into the flask / blackjack, do not expose it to high temperatures, direct sunlight, aggressive fluids, oils, or high pressure. Breaking these principles can cause deformation and loss of ability to maintain liquid. After emptying the product, rinse it thoroughly with clean water and allow to dry. Do not leave the flasks closed unless they are completely dry.
